• Many features of Ginkgo biloba var. epiphylla Mak. , the one which was firstly found at Yiyuan
  County of Shandong Province in China, were continually observed and the comparative morphology research
  was conducted, including the variation characteristics, the morphological development of ovule-like organ on
  the leaf blade and veins of leaf. The results of analysis showed that the development of the ovule-like organ on
  the leaf blade is comp rised of initial stage, formation stage, expansion stage and mature stage. There were one
  to eight ovule2like organs on each leaf, but only one developed normally. The leaves were divided into five
  types, i. e. multilobed type, nonlobed type, bilobed type, the leaf with ovule-like organ and deformation
  leaf, leaf color into two types, i. e. green and variegated types. Compared with normal ovules, ovule-like
  organ on the leaf blade disp layed variation in insertion, heterochrony and hysteresis in development of ovule-
  like organ on the leaf blade, which was reported for the first time. The ovule2like organ lagged behind the nor-
  mal ovule for fifteen days at initial stage, moreover no pollination drop was found on the ovule2like organ. The
  ovule2like organ on the leaf blade was divided into five types according to the insertion on the leaf, i. e. uni-
  lobed solitary type, unilobed clustered type, bilobed clustered type, multilobed solitary type and adsperse
  type. The vein of normal leaf could be separated into four types according to anastomoses, i. e. closed type,
  W type, V +W type and double V +W type. And that of the phyllosporous leaf was classified into three
  types, i. e. uni-arcuate, biarcuate and mutli-arcuate type. The variation characteristics and the phylogeny of
  Ginkgo biloba var. epiphylla Mak. were discussed in the paper.

• The vessel elements of secondary xylem in Manilkara zapota were observed by bio-microscope
  image analysis system and micrography. There were various patterns of vessel elements in M. zapota and most
  of the vessel elements had tail. Perforation p lates could be divided into two types: 1. Both ends of the vessel
  element were simp le perforation p late; 2. One end had simple perforation, the other had two simp le perfora
  tions. And there were a series of transitional patterns between the two types. Three percent of vessel elements
  of secondary xylem in the p lant had inclusions. Intervascular p itting was alternate p itting. There were mixed
  type p itting, gash-like p itting and perforation between vessel elements and ray cells.

• Structural and Developmental Characteristics of Floral Nectaries ofDimocarpus longan
• NING Xi-ping;WU Hong;LUO Shi;LAI Yong-chao
• Acta Horticulturae Sinica. 2007, 34(1): 11-16.
• Abstract ( 2134 ) HTML ( 2002 ) PDF (1155KB) ( 2002 ) 　　　
• The structure and development of floral nectaries of Dimocarpus longan were studied with
  scanning electron microscopy ( SEM ) , paraffin section, thin resin sections and transmission electron
  microscopy (TEM). The floral nectaries ofmale and female flowers of Dim ocarpus longan were located on the
  surface of floral recep tacle, which formed a convex disc-like nectary. The nectarywas located at the outer part
  of the pistil and stamen and at the inner part of corolla and calyx. The male and female flower nectaries,
  composed of epidermis, nectariferous tissue and vascular tissue containing only phloem elements, belong to
  typical structural nectaries. The epidermis of floral nectaries was covered with numerous epidermal hairs
  consisting of single cellwith thickened wall and cuticle. In addition, some small stomata were observed at the
  top surface of nectaries. There were a lot of granulose phenolic compounds within most ep idermis cells. Two
  types of cells could be distinguished in nectariferous tissue, one was smaller and had densely stained cyto
  p lasm, anotherwas larger and contained phenolic compounds. The former consisted ofmore cells than the lat
  er. The nectaries had well-developed vascular tissues, which derived from the branches of the vascular bundle
  of floral recep tacle, then they terminated nearby ep idermis. Normally the nectariesps p rimordia ofmale and fe
  male flower ofD. longan were found to initiate in surface of recep tacle after other floral organswere differenti
  ated. During the development of floral nectaries, especially before and after the nectar secretion, the vacuole
  volume ofmost of nectariferous tissue cells changed regularly, which imply that they may be involved in the
  p rocess of nectar synthesis and secretion. Some phenolic compounds in specialized cells of nectariferous tissue were disintegrating during nectar secretion, so besides its p rotective function in floral nectaries, the phenolic
  compounds were likely to take part in synthesis of nectar.

• Abstract ( 1936 ) HTML ( 1359 ) PDF (213KB) ( 1359 ) 　　　
• In order to exploit the evolution of genes of apricot native to China, the frequency distribution
  of several biological characters of apricot in different eco-geographical groups (North China, Central Asia,
  Dzhungar - Zailij) native to China were analyzed in the study. In general, self-incompatibility was a common
  character for the three eco-geographical groups with averages less than 2.0% and the percentages of self
  incompatible cultivarsmore than 90%. Therefore, a few self-compatible germp lasmswere found, too. Higher
  sterile flower rate of 40% was observed in all eco-geographical groups with a higher coefficient variance of
  50%. For a certain cultivar or form, the trait was relatively stable. Glabrous-fruited cultivars were only ob
  served in Central Asian eco-geographical group with a higher percentage of 76.6%. In other two group s, the cultivars or forms were all identified as rough skin-fruit. The largest fruit size (with an average of 51.4 g) was
  a predominate trait in North China group compared with those of Central Asian group (23.2 g) and Dzhungar
  - Zailij group (8.2 g). In the three groups, the rate of freestone-fruited cultivars or forms was remarkably
  higher than those of clingstone. The frequencies of freestone were different among the group swith the highest
  frequency of 94.6% in Dzhungar - Zailij group and the lowest frequency of 58.8% in North China group. The
  highest value of the total soluble solid wasmeasured in Central Asia group (18.5% ). The total soluble solid
  was greatly affected by environmental factors indicating itwas an classical quantitative trait. For cultivars from
  North China, the valuesmeasured from Shandong (13.1%) and Xinjiang (16.1% ) were different very sig
  nificantly ( F = 42.361, P < 0.01). The highest rate of sweet kernel (93.1% ) was observed in the Central
  Asian eco-geographical group compared to Ili wild population ( 0.9% ) and North China group ( 44.4% ).
  The effect of artificial selection and natural selection on the origin and evolution of the characterswas also dis
  cussed.

• The internal transcribed spacer ( ITS) regions of nuclear ribosomal DNA from 8 species of
  Amygdalus L. were sequenced, and analyzed togetherwith other ITS sequences ( from GenBank) of 18 species
  representing genera Cerasus Mill. , Armeniaca Mill. , and Prunus L. Taking Padus racem osa (Lam. ) Gilib.
  and Padus buergeriana (Miq. ) Y et Ku as outgroup s, phylogenetic analysis of ITS sequences was made by
  using PAUP410b4a software. Resusts indicated that 1) The consensus tree could be divided into two main
  clades, CerasusMill. and the remaining genera, supported by bootstrap values of 68% and 100%, respective
  ly. 2) Species of CerasusMill. formed a basal group (Clade Ⅰ). Prunus L. , Arm eniaca Mill. and Amygda
  lus L. formed a monophyletic group (CladeⅡ) with bootstrap value of 100% , which imp lied that they had
  close relationship swith each other and probably had a common origin. CladeⅡwas divided into two subclades. One was Amygdalus L. , and the other was Prunus L. and Armeniaca Mill. Bootstrap values for these two
  subcladeswere 100% and 54%, respectively. The evolutional and taxonomic relationship s of stone fruitswere
  discussed based on the phylogenetic analysis of ITS sequences, morphological characters and geographical dis
  tribution.

• Interspecific Hybridization of Prunus persica with P. armeniaca and P.salicina Using Embryo Rescue
• LIU Wen;CHEN Xue-sen;LIU Guan-jun;WU Yan
• Acta Horticulturae Sinica. 2007, 34(1): 29-34.
• Abstract ( 2129 ) HTML ( 1938 ) PDF (498KB) ( 1938 ) 　　　
• Some interspecific hybrids were obtained after hybridization of Prunus persica with treated
  pollens from P. armeniaca and P. salicina, then the hybrid embryos were successfully rescued, and a molecu
  lar identification wasmade in part of the hybrids. The results showed that the hybrid embryo abortion started
  from the 7 th or 8 th week after pollination in cross when used the Yuhualu or Zhonghua Shoutao as the female
  parent. The cultivarswith different durations for fruit development and the ages of hybrid embryos have great
  effects on the rate of embryo germination and growth. At the same age (when the PF value was around 0.5) ,
  the late peach cultivar Zhonghua Shoutao acquired more than 50% of embryo germination rate, but the early
  peach cultivar Yuhualu gave only 6.7% of it. Treatment of male parent pollen in the electrostatic field at an
  app rop riate dosage imp roved the efficiency of bud inducement and multip lication, but treatment with ⁶⁰Coγ
  ray reduced the efficiency and p roduced weak buds. For rescuing the hybrid embryos, it is concluded that the
  medium 1 /2MS + 6-BA 4 mg·L^-1 + IBA 0.5 mg·L^-1 can increase the embryo germination rate up to
  90% , the MS + 6-BA 1.0 mg·L^-1 + IBA 1.0 mg·L^-1 is the bestmedium for bud induction and multip li
  cation, and the MS + IAA 0.5 mg·L^-1 + NAA 0.2 mg·L^-1 is the best rootingmedium. SSR identification
  proves that the hybrids obtained by the embryo rescuing system are true ones.

• A total of 29 sand pear germp lasm (mainly red skinned) native to southwest of China were
  subjected to simp le sequence repeat ( SSR) analysis. Six pairs of SSR p rimers (BGA35, KU10, BGT23b,
  NH004a, NH011b and NH015a) could generate a large number of alleles. The p rimer NH004a, which p ro
  duced the highest allele numbers and the most effective alleles, and high heterozygosity and Shannon informa
  tion index, showed the best identification power. Using six pairs of SSR p rimers, all accessions or types could
  be distinguished excep t for three pairs of cultivars, which might belong to the synonymy cases or bud mutants.
  Twenty nine pear accessions could be divided into fourmajor group s obviously based on the UPGMA cluster a
  nalysis. Group Ⅰ consisted of cultivars all native to Yunnan p rovince, including two green and nine red
  skinned sand pears, inferring a near genetic relationship between the red and green skinned pears. In groups
  Ⅱand Ⅲ, the red skinned pears from Huili County of Sichuan Province and from Yunnan Province mingled to
  gether, which might suggest cultivarmovement from Yuannan to Sichuan. In group Ⅳ, not onlywere Xiangsu
  li and Zaiyangli from Huili County of Sichuan Province, Midu Xiangsuli and Changshui Huobali native to Yun
  nan Province not closely clustered, but also were far from other groups. Huobali pear types distributed in Yun

• The detection technique of Apple chlorotic leaf spot virus (ACLSV) in pear plant by IS-RT-
  PCR with Digoxigenin labels for leaf paraffin slice samp les and shoot tip s frost slice samples was established
  in this paper. Korla pear leaves infected by ACLSV and virus-free seedling leaves of Pyrus betulaefolia Bge
  as control were used as leaves materials in the tests. The IS-PCR parameters including concentration of
  dNTPs, RNasin, Taq DNA polymerase, Mg²⁺ and p rimers, effect ofAMV reverse transcrip tase and comple
  ment primer on cDNA synthesis, annealing temperature and cycle number were studied systematically. The
  results showed that the stain signal strength increased accompanied with an increase of RNasin amountwhen
  its concentration reached over 0.2 U·μL^-1. Certain amount of cDNA would not be generated until the con
  centration of dNTPs reached 1.0 mmol·L ^-1 in reaction solution. Reverse transcrip tion could be carried out
  when the concentration of AMV reverse transcrip tase was between 0.3 U·μL^-1 and 0.5 U·μL^-1, and the
  quantity of cDNA p roduction imp roved with the increase of the concentration ofAMV. The reverse transcrip
  tion could not be carried out until the concentration of antisense p rimer reached 0.9μmol·L ^-1 , and the a
  mount of cDNA would increase alongwith the increase of primers concentration. The suitable annealing tem
  perature for in situ amp lification of cDNA was 56℃. The minimum amp lification cycle number was 20 times. The stain signal was weak when primer concentration was less than 018 μmol·L - 1 and the signal
  color was heavy blue as the concentration of Taq DNA polymerase was over 20 U·mL ^-1; In situ PCR could
  be performed whenMg ²⁺ concentration was at 1.5 mmol·L^-1. An op timized detection system of ACLSV

  was quite long ( 46 - 75 min) , the photosynthetic induction was the fastest in Reveille, whereas it was the
  slowest in Sunrise. The CO₂ compensation points were rather high ( 89 - 121 μmol ·mol^-1 ) in the 4
  cultivars, indicating that all of the 4 cultivars are typ ical C3 p lants. Compared to southern high2bush blueber
  ries, the northern high2bush blueberries Sunrise and Jersey had higher photosynthetic ability, carboxylation
  efficiency, the maximal photochemical efficiency of PS Ⅱ and saturation light intensity. In addition, the
  Sunrise had the lowest light compensation point and characteristics of shade tolerant p lant. However, the
  op timum photosynthetic temperature was lower and the range of itwas narrower (23 - 25℃) , indicating that

• Establishment of a stable embryogenic cell suspension ( ECS) is a prerequisite for biotechno
  logical breeding of banana. Although many important p rogress has been made, but app lication of embryogenic
  cell suspension for genetic imp rovement ofM usa is limited because of low induction percentage of embryogeno
  ic callus, low conversion frequence of p lant regeneration from the somatic embryos. Therefore, an op timal pro
  tocol for embryogenic cell suspensions is still required to establish. In this study the effects of Picloram, ABA
  and TDZ on somatic embryogenesis of banana from youngmale flower of Musa acuminata cv. Mas (AA) were
  investigated. Results showed that the induction percentage of embryogenic calli reached 15.6% when 2, 4-D
  in the callus induction medium was substituted by 8.28 μmol/L picloram. However, the addition ofABA into
  somatic embryo development medium inhibited somatic embryogenesis from embryogenic cell suspension and
  resulted in callus formation from somatic embryos. Treatmentwith TDZ at concentration of 0.2 μmol/L resul
  ted in increase of the percentage of germination of somatic embryos from 17.28% to 72.77% and the plant
  conversion ratio from 16.49% to 67.05% , respectively.

• Several factors affecting isolated microspore culture of non-heading Chinese cabbage
  (Brassica campestris ssp. chinensis) were studied in experiments. The results from mono2factor experiments
  showed that there were significant differences in the frequency ofmicrospore-induced embryos among different
  genotypes. In the low temperature treatment, no significant differences were found during 0 - 5 days, while
  the frequencies were obviously lower when the period was longer than five days. There were no significant
  differences in high temperature when the incubation time was within 12 - 60 h, but the frequencies of
  microspore-induced embryos were much lower over this duration. The addition of auxins (NAA ) and the
  cytokinins ( 6-BA) in NLN medium showed no significant effect on the frequencies of microspore-induced
  embryos, but when the concentration was excessive, the frequencies decreased. The presence and
  concentration of activated charcoal had a great influence on the frequency ofmicrospore-induced embryos. Mo
  reover, four-factor analysis of genotype, auxin, cytokinins and activated charcoal concentrations indicated that
  there were significant differences among different genotypes and activated charcoal concentrations,
  respectively, and also significant differences among these two interactions, while other interactions remained

• On the basis of one cDNA-AFLP differential fragment isolated from the fertile Bline of
  Chinese cabbage-pak-choi (Brassica campestris L. ssp. chinensis Makino) nuclear recessive sterile A /B line
  (Bajh97201A /B) , the full length DNA and cDNA of BcMF6 gene encoding pollen2specific polygalacturonase
  were cloned by rapid amplification of cDNA ends (RACE). The gene consisted of 1 194 bp encoding a
  protein of 397 amino acids and was interrup ted by three introns of 81 bp, 95 bp and 127 bp in length.
  Sequence analysis revealed that it has three N-glycosylation sites, four protein kinase Cphosphorylation site,
  five casein kinaseⅡphosphorylation site, ten N-myristoylation sites and one polygalacturonase active position
  (²²⁷RVTCGPGHGIS1 IGS²⁴⁰ ). And the first 22 amino acids of the predicted BcMF6 protein form a N-terminal
  hydrophobic domain which disp layed the p roperties of a signal peptide and four parallel beta-helix repeats
  followed behind. Four domains which were highly conserved in all p lant and fungal PGs was p resent in
  BcMF6. Phylogenetic analysis showed that BcMF6 falls into the category of clade2C, which included PG
  related to pollen. These results showed that BcMF6 acts as pollen-specific polygalacturonase. Furthermore,
  the exp ression using RT-PCR discovered that BcMF6 was exclusively exp ressed in middle and big flower bud,opened flower and slow pod of fertile line (wild type) , which showed BcMF6 closely related with the develop

• In an effort to study the molecular mechanism of genic male sterility in plants, BcMF3 gene
  that encodes a pectin methylesterase ( PME) was isolated from the fertile B line of Chinese cabbage-pak-choi
  (Brassica campestris ssp. chinensis var. communis, syn. B. rapa ssp. chinensis var. communis) previously.
  In the present paper, primerswere designed based on the cDNA sequence of B cM F3, and a 458 bp fragment
  and a 538 bp fragmentwere amp lified from the cDNA of flower buds of Chinese cabbage-pak-choi. These two
  fragmentswere introduced into binary vector pB I121 in antisense orientation and sense orientation respectively,
  and the generated RNA interference (RNAi) vector was then mobilized into Agrobacterium tum efaciens strain
  LBA4404. The A. tum efaciens harboring the BcMF3 fragment was transformed to flowering Chinese cabbage
  (B. campestris ssp. chinensis var. parachinensis) via tissue culture. The pollen grains from app roximately
  50% of RNAi plants exhibited abnormal shapes, and only 32.3% of pollens from RNAi plants germinated nor
  mally. The PME activity of the anther from RNAi plants with abnormal pollens decreased by 13.5%. These
  results showed that functional interruption of BcMF3 by RNAi resulted in pollen abortion in flowering Chinese
  cabbage, which p robably caused by the decrease of PME activity. The study suggests that the product of
  BcMF3 gene plays an important role during pollen development in Cruciferae crop s such as flowering Chinese
  cabbage and Chinese cabbage-pak-choi.

• Gas exchange, chlorophyll fluorescence and bio2analysis were used to study the influence of
  carbohydrate allocation on net photosynthetic rate in leaves of tree peony ( Paeonia suffruticosa ‘Rou Furong’)
  brancheswith and without flower. The results showed that before flower senescence, the net photosynthetic
  rate in leaves on brancheswith flower ( FL) was lower than that in leaves on brancheswithout flower (NFL).
  Whereas the total soluble sugar content was higher in the FL than that in the NFL. Compared with that at
  17∶00 on the p revious day, after a night consump tion, the total soluble sugar content in the NFL decreased
  obviously at 8 ∶00 a1m. while that in the FL hardly changed. These results indicate that there were other
  sources to supp ly soluble sugar in FL besides photosynthesis during the florescence period. After flower senes
  cence, differences in net photosynthetic rate and total soluble sugar content between the NFL and the FL dis
  appeared gradually, and the total soluble sugar content in both the FL and the NFL was lower at 8: 00 a. m.
  than that at 17∶00 on the p revious day, which suggest that the other sourcesmentioned above did notwork to

• By controlling the soilwater content, 1-year-old potted cutting plants of Photinia frasery as the
  materials, the effects of drought and flooding stress on the changes of malondialdehyde (MDA) content, the
  membrane permeability, p igment content aswell as photosynthetic and physiological characters in summer and
  autumn were studied. The results showed that MDA content, membrane permeability and anthocyanin (Ant)
  content were distinctly increased, while the content of chlorophyll, the index values of net photosynthesis rate
  ( Pn) , water use efficiency (WUE) , apparent quantum yield (AQY) and carboxylation efficiency (CE) were
  decreased. Meanwhile the available light intensity range was shortened with the declining of light saturation
  point (LSP) and rising of light compensation point (LCP) under drought and flooding stress in summer and
  autumn. On the other hand, the chlorophyll (Chl. ) content of control in summer was lower than that in au
  tumn, but the values of Pn and CE in summerwere higher than these in autumn. In addition, the membrane
  injury of Photinia frasery under drought and flooding stress in summerwasworse than autumn, the degradation
  of Chl. in summerwas lower than autumn, the carotinoid (Car. ) content increased in summer and decreased
  in autumn, the decrease of LSP and increase of LCP in summerwere lower than autumn, but the decrease of
  Pn under drought stress in summer was lower than autumn, and the decrease of Pn under flooding stress in summerwas higher than autumn; moreover, flooding in summer had much more influence on membrane injury
  and Pn, WUE, AQY, CE than drought stress, the decrease of Pn in initial stage was due to stomatal limita
  tion, and then nonstomatal limitation dominated. The gray relational grade analysis showed that the relation
  ship among climate factors and Pn ( from high to low) were temperature of atmosphere (Ta) , CO₂ concentra
  tion and photon fluxdensity ( PFD). While drought in autumn had much more influence on membrane injury
  and Pn, WUE, AQY, CE than flooding stress, the decrease of Pn wasmainly decided by nonstomatal limita

• The passivation effect of high hydrostatic p ressure on POD ( peroxidase) of strawberry was
  studied by response surface methodology. Experimental results showed that high hydrostatic p ressure could
  passivate POD significantly. Based on analysis of the factors (p ressure, temperature and time) and their inter
  action, it was found that p ressure was a key factor to passivate POD under the conditions of this experiment.
  A model, y = 97.2 - 44.0x₁ - 1.1x₂ - 5.3x₃ - 27.5x₁² - 7.3x₂² - 9.4x₃² - 8.3x₁x₂
  - 5.0x₁ x₃ + 26.9x₂ x₃ ,
  was established by Design Expert software. The determination coefficient of model was 0.9883 and adjusted
  determination coefficientwas 0.9732. Analysis of variance imp lied that the modelwas significant. Therefore,
  the model could be used to analyse and predict activity passivation of POD.

• With a F₂ population derived from 66 ×A18 asmaterials, polymorphism between resistant and
  suscep tible bulk of cucumber anthracnose were studied using BSA method and AFLP technology. A codomi
  nantAFLP marker, E24M48=251 bp /245 bp, was screened. The resistant and suscep tible F₂ plants possessed
  the 251 bp and the 245 bp fragment, respectively, and the mid-plants owned the two fragments. The AFLP
  markerwas closely linked with the cucumber anthracnose resistance related gene, and the genetic distance be
  tween the marker and gene was 21727 cM. Fragements sequencing of the codominantAFLP marker indicated
  that their length were 251 bp and 245 bp, respectively. The difference of the two fragements lied in the insert

• The dynamic changes of RR ( resp iratory rate) , SPC ( soluble p rotein content) , SSC ( sol
  uble sugar content) , SOD, POD, endohormone IAA and ABA in different parts of three onion varieties ( in
  cluding early2maturing, middle2maturing and late maturing types) with differentmaturities during the dorman
  cy stage were studied. The results suggested that the length of physiological dormancywas different among the
  three varieties, the dormancy period of the late2maturing variety Gangcong 841 was the longest ( about 70 d)
  and the early2maturing variety Yangchunhuang was the shortest ( about 40 d). The resp iratory rate, SPC and
  the activity of SOD, POD showed a rap id rising trend and then falling trend before the end of physiological dor
  mancy. The SSC decreased rap idly after physiological dormancy. The content ofABA was highest in the early
  dormancy period, afterwards, a rap id falling until the end of physiological dormancy. Change of IAA was
  rightly reverse to ABA. The distribution of these physiological and biochemical data were interior scales >mid
  dle scales > exterior scales. It is concluded that the higherABA, lower IAA, SPC and higher SSC are benefi
  cial to remain dormancy after harvest.

• Effects of light and sugar on Gerbera hybrida ray floret ( rf) p igmentation were investigated.
  Inflorescences or rfs at stage P2 were detached and incubated on the medium (8 g·L^-1 agarwith 3% sucrose
  or free of sucrose) under 14 h light /10 h dark cycles at 23 - 25℃. Cultured inflorescences and rfswere first
  incubated in darkness for 3 d, then exposed to transient light for a period of time followed by an incubation in
  the dark until harvesting for anthocyanin determination by spectrophotometer at 9 th d or harvested immediately
  for gene exp ression detected byNorthern-blot. The results showed that transient light exposure induced antho
  cyanin accumulation and the gene exp ression of CHS and DFR in rf petal after 3 d p reculture in darkness. The
  longer time of light irradiation strongly enhanced the gene exp ression of CHS and DFR . Petals precultured in
  darkness for 7 d and 9 d had weak response to light in gene expression. When sucrose was present in the me
  dium, both anthocyanin accumulation and gene exp ression were strongly increased under light condition.

• Hedychium is a perennial herbaceous genus belonging to Zingiberaceae. Aroma production
  differs among different Hedychium species. Studies on the aroma componentswill help uswith the understand
  ing of their biosynthesis and with the breeding of new varieties via bioengineering. In this study, gas chroma
  tography-mass spectrometry combined with solid-phase microextraction ( SPME - GC - MS) was developed for
  the determination of aroma components in four different Hedychium s species, namly H. coccineum, H. gard
  nerianum, H. f lavum and H. coronarium , which have different fragrance. The results showed that the aroma
  components and contents in the four Hedych ium s specieswere different. The relative aroma content in H. coc
  cineum was only 1.21 μg·h^-1·g^-1 FM, but that in H. gardnerianum , H. f lavum and H. coronarium were
  16.80, 13.64 and 17.36 μg·h^-1·g^-1 FM, respectively. L-linalool and 1, 8-cineole might be the charac
  teristic aroma components in Hedychium.
