• The experiments were conducted in an 8 years old grape orchard, ‘Red Globe’, to study the effect of sunlight, air temperature, wind speed and other factors on grape berry sunburn. The results showed that the higher temperature on fruit surface was the direct factor inducing grape sunburn. The threshold temperatures to induce sunburn ranged from 42.0℃ to 42.8℃(average temperature was 42.3℃) during fruit fast swell stage. It would reach to maximum after 12 minutes if the berries were suddenly exposed to the sunlight. The excessive sunlight increased both air temperature and fruit surface temperature. Therefore, excessive sunlight was the most important factor causing grape sunburn. The illumination per 10 000 lx could add about 1℃ on fruit surface at noon of a shiny and windless day in summer. The fruit surface temperature was significantly higher on the days without wind than when the wind speed was 1.5m﹒s^-1. When wind speed approached 3.0m/s, the fruit surface temperature decreased to a very low level within 6 minutes. The higher relative humidity increased grape sunburn under the same light and temperature conditions.

• The mature fruits of post-harvest ‘Jingmi’grape were irradiated by the dosage of 3.6 kJ·m^-2 ultraviolet C (UV-C) and then incubated 24 hours in dark at 25 ℃. The UV-C irradiated berries and control berries were stored at 0 ℃ and 25 ℃. The berries was sampled at 0, 0.5, 1, 2, 3, 7, 10,14, 24 and 34 d. Resveratrol and piceid content in grape berries was determined by HPLC. The results showed: Trans-resveratrol (trans-Res) and cis-Piceid (cis-PD) content in grape berries skin was significantly increased when treated by UV-C irradiation and then incubated 24 h in dark at 25 ℃, but trans-Piceid (trans-PD) content in grape berries skin was not significantly increased. Storage temperature played an important role on the level of Res and its glycosides by UV-C irradiation treatment. cis-Resveratrol (cis-Res)could not detected in skin of UV-C irradiated berries and control berries.trans-Res, trans-PD and cis-PD content of control grape berries skin was low and stable under 25 ℃ and 0 ℃, while UV-C irradiated berries skin was higher than control at mostly sampling time and changed sharply.

• Abstract ( 2046 ) HTML ( 2068 ) PDF (2116KB) ( 2068 ) 　　　
• To investigate whether exogenous-H²O²-induced drought tolerance is mediated by the increasing of antioxidant activities, agreenhouse-ecotype cucumber ‘Chunguang 2 ’was pretreated with exogenous hydrogen peroxide (H₂O₂ ) and was subjected to drought stress, which was simulated by 100 g·L ^{- 1} polyethylene glycol 6000. Without pretreatment of exogenous H₂O₂ , drought stress resulted in plants with round chlorop lasts, the indistinct chlorop lastmembranes and thylakoids. Compared to drought treatment itself, the combination of H₂O₂ pretreatment and drought stress did not change the chlorop last ultrastructure obviously, and it not only increased the activities of antioxidants such as superoxidedismutase, catalase, guaiacol peroxidase, ascorbate peroxidase, monodehydroascorbate reductase, dehydrateascorbate reducatase, glutathione reductase,ascorbic acid and the reduced glutathione, but also decreased the contents of malonaldehyde, endogenous H₂O₂ and superoxide radical. We conclude that the app lication of exogenous H₂O₂ increases the antioxidant activities, and therefore decreases the accumulation of reactive oxygen species and alleviates the damage to chlorop lastmembranes under drought stress.

• Study was conducted to explain the reason why grafted cucumber (Cucumis sativus L. ) performs better than non-grafted one in the respect of resistance or tolerance to biotic orabiotic stresses and photosynthesis. In a plastic chamber, grafted cucumber‘Jinyou 1’ and non-grafted cucumber‘Jinyou 1’were planted in plastic pots filled with pasterised medium consisting of peat, vermiculite and moss. Proteins from the leaves of the two types of cucumber p lants were analyzed in seedling stage, flowering stage and fruiting stage by two dimensional electrophoresis ( 2-DE) and mass spectrum (MS). In the leaves of the grafted‘Jinyou 1’, two types of proteins were found to be induced to higher degree of expression than in the non-grafted plants. The first type of p roteins was R-protein (RGC693) and squalene synthase related to resistance
  or tolerance to the stresses. The second was coenzyme which promotes chlorop last synthesize, and chlorophylla-b binding protein which enhances photosynthesis. So the results obtained in this research could partly explain the mechanism of the better stress tolerance and higher photosynthesis in the grafted cucumber plant.

• Late blight, caused by the oomycete Phytophthora infestans (Mont. ) de Bary, is a devastating disease of the two Solanaceous crops, tomato and potato, and caused serious economic loss. Potato late blight resistant genes R3a, R1 and RB were cloned recently. In order to determine whether these resistance
  genes have function in tomato plants, R3a, R1 and RB were transferred separately into tomato plants by Agrobacterium-mediated transformation method. The transformants showed hypersensitive response (HR) to 89148-9, the potato late blight isolate race 0. Transgenic tomato p lantswere also inoculated with 5 tomato late blight isolates, and the results demonstrated that R3a and R1 showed resistance to some tomato late blight isolates, while RB showed resistance to all 5 isolates. These results suggested that it be possible to use potato late blight resistance genes RB to protect tomato from late blight

• Cytoplasmic male sterility (CMS) celery is useful for hybrid seed production. Asymmetric protop last fusion of fertile celery and petaloid CMS carrot was carried out by polyethylene glycol ( PEG) 6000 treatment in order to introduce CMS from carrot to celery. Protop lasts of celerywere treated with 6 mmol·L ^{- 1}
  iodoacetamide for 7 min to passivate cytoplasm, and those of carrot were continuously irradiated with UV rays(20 μmol·m^{- 2} ·s^{- 1} ) for 9 min to kill the nucleus. Low temperature (5 ℃) increased aggregation rates by 20% , and 40% PEG 6000 and 0.1 mmol·L ^{- 1} Ca²⁺ in high Ca²⁺ high pH solution were the best for fusion of two protoplasts. Twelve somatic hybrids were obtained and plants were regenerated on MS₀ medium. AFLP analysis indicated that all of them were somewhat asymmetrically fused. STS marker analysis suggested that petaloid CMS were successfully introduced into 11 regenerated plants.

• To clarify the mechanism of flower opening and senescence in tree peony ( Paeon ia suffruticosa) ‘Luoyanghong’and‘Huhong’, we investigated sugarmetabolism in the petals of two tree peony cultivars. The results showed that total soluble sugar content increased rap idlywith the cell enlargement in the petals and during flower senescence. The contents of hexoses (glucose and fructose) markedly increased during flower opening and reached a highest level at full-opening, but the content of sucrose dropped gradually. The hexose content and sucrose degradation index ( SDI) were positively correlated with the fresh weight of flower. The activity for acid invertase (AI) increased during flower opening and decreased after the flowers opened. Based on regression analyses, the soluble sugarmetabolism was related to the actions of the 4 enzymes, viz1 acid invertase (AI) , neutral invertase (NI) , sucrose synthase (SS) and sucrose phosphate synthase ( SPS). Our results suggest that hexose accumulation in the petal might be important for flowering opening and senescence in tree peony.
