• The parthenogenic young embryos were gained in apple varieties (Bela , Liaofu and Fuji) due to pollination with radiated pollen by 1 000 - 1 500 Gyγ ray. The haploids of these varieties were produced by young embryo culture and regeneration. The investigation indicated that major factors which limited hapliod production efficiency in apple by such technique included abscission of
  fruits in early stage , young embryo abortion and difficulty in regeneration of young embryo with endosperm. The results also suggested that regeneration of 25 d young embryo (ovule) was available.

• The calcium contents in all parts of bitter pit apples were significantly lower than that of the sound ones , but only the contents of magnesium at the outer cortex significantly higher than the sound ones. The activities of superoxide dismutase (SOD) , peroxidase ( POX) , catalase (CAT)
  and ascorbate specific peroxidase (APX) in the pitted fruits were significantly lower than that of the sound. Vacuum infiltration of apples with CaCl₂ 100 mmol/ L increased activities of the above antioxi dant enzymes , and the treatment of MgCl₂ decreased the activities of POX, APX and CAT , implying
  the activities of these three enzymes were regulated by calcium. The contents of malonaldehyde and the relative conductivity were higher in bitter pit apple fruits , which showed that the peroxidation of membrane might be the important reason of the physiological disorder in apple with lower level of calcium.

• A peach cultivar‘Hujingmilu’was used to investigate the changes of LOX activity , ethylene production and memberane fatty acid composition. It was found that the major fatty acids in the ripening peach fruit included palmitic acid (16∶0) , stearic acid (18∶0) , oleic acid (18∶1) , linoleic acid (18∶2) and linolenic acid (18∶3) . There were remarkable changes in the proportion of
  oleic acid , linoleic acid and linolenic acid , especially linoleic acid and linolenic acid , while no such notable changes in the proportion of palmitic acid and stearic acid during fruit ripening at 20 ℃. Linolenic acid was mainly used as a LOX catalyzing substrate before LOX self-propagation during fruit
  ripening at 20 ℃. LOX might play a role in memberane lipid peroxidation which participated in fruit ripening and softening. The significance of these results was discussed.

• China possesses more than 70 % ginkgo resources in the world. The primary problems existing in ginkgo cultivation are : (1) no big-grain and fine nucleus-used cultivars ; (2) no known genetic law of primary characters ginkgo seed. The purposes of this research are to collect 50 nucleusused cultivars from 12 provinces in China , to carry out genetic analysis for economical character and
  multiple character selection on ginkgo seed. The results of analysis show that maxmum single nucleus weight , stone mass/ fruit mass ( %) and kernel mass/ stone mass ( %) are 3. 89 g , 33. 58 % and 82. 49 % , respectively. The heritability ( h2) of single nucleus mass is 0. 9759. The genetic correlation coefficient ( rG) between nucleus2shape coefficient and single nucleus mass , and direct genetic path coefficient ( PY·i) of single fruit mass to single stone mass are 0. 9986 and 1. 407 , respectively. Twelve provenances from China are divided into four classes. Three fine nucleus-used cultivars are selected out through index or direct selection methods from fifty nucleus-used cultivars in China. The theory of nucleus2used cultivar selection was studied in this paper.

• Abstract ( 1289 ) HTML ( 1886 ) PDF (211KB) ( 1886 ) 　　　
• The tests of daily variation of photosynthetic rate of butterhead lettuce grown in green house are conducted. The results show that the daily variation of photosynthetic rate is a two peak curve in sunny days in summer and autumn season. While in winter with lower temperature, it is a
  one-peak curve pattern. In the cloudy and raining days, the change of photosynthesis just follow the change of radiat ion. The photosynthesis maintaining at its high value is not more than 3- 4 hours within a day. If the radiation and temperature cannot meet the need of crop in the morning, it is still possible to produce a photosynthet ic peak in the afternoon with suitable environment factors for the crop photosynthesis.

• Wang Yongzhang and Zhang Dapeng
• Acta Horticulturae Sinica. 2001, 28(3): 256-261.
• Abstract ( 1508 ) HTML ( 2383 ) PDF (150KB) ( 2383 ) 　　　
• The changes of sugar accumulation and related enzyme activities in sugar metabolism of ‘Red Fuji’apple fruit showed that the activities of soluble and cell wall2bound acid invertase had significant negative correlation with
  soluble sugar contents in the early stage of fruit development. However , the activity of sucrose synthase showed a highly positive correlation with sucrose accumulation in the late development stage. It is concluded that the sucrose metabolism in apple fruit may be mainly mediated by acid invertase and sucrose synthase.

• Abstract ( 1414 ) HTML ( 1010 ) PDF (164KB) ( 1010 ) 　　　
• The studies of the formation and development of the sexual organs on the primary and secondary flower cluster of 􀀂Kyoho grapevine were conducted, aiming at elucidating the mechanism of the low seed production on the
  primary flower clusters. The results showed that the pollen of the florets of the secondary flower clusters was smaller, though the percentage of pollen stained by acetocarmine on florets of both flower clusters was same, the percentage of germination on agar of the secondary flower clusers was higher than that of the primary flower clusters. The result indicated that the pollen quality was not related to flower shatter. The embryo-sac evelopment with function cell in the pistils of the secondary flower clusters was more favorable than that of the primary flower clusters. At anthesis, a large number of abnormal embryo􀀁sac were observed in the ovaries of the primary flower clusters. As a result, at anthesis, a large number of abnormal embryo􀀁sac may suppress fertilization and lead to lower seed.
