Effects of Temperature and Photoperiod on Sex Expression of Momordica Charantia
Wang Qiaomei;Zeng Guangwen;Jiang Youtiao
   1997, 1 (1): 1-0.  
Abstract （1053）      PDF（pc） （174KB）（896）       Save
The environmental conditions under which Momordica charantia seedling grew affected its sex expression. Both varieties“Zhuzhou Changbai”and“Yingyin”were short-day plants,the short day length resulted in earlier plant development and more female flowers. The short-day treatment period of Momordica charantia seedlings should be from the day when the seedlings were first emerged to the day when the sixth leaf appeared(at age of 20 days). Low temperature enhanced the short-day effect,while high temperature dela...

   1997, 1 (1): 2-0.  
Abstract （1023）      PDF（pc） （173KB）（900）       Save
A rapid method of identifing resistance to anthracnose of Chinese cabbage in seedling stage and reflecting adult resistance was developed by testing different inoculating methods,temperatures,plant ages and inoculum concentrations. The suspension of 6 000～12 000 conidia/mL was dripped on to the cotyledon of Chinese cabbage seedlings at cotyledon stage and kept at the temperature of 20～32℃ in 100% moisture for 24～48 hours.

Abstract （1172）      PDF（pc） （212KB）（824）       Save
The scallion anthracnose started occurring from the end of April to the begining of May in Zhoushan Island,Zhejiang,China. It reached maximum at the middle or the last ten days of May. A moderate temperature and heigh humidity were the important factor for the disease epidemic. Irrigated or continuous cropping field was in favor of the disease occurance. The yield loss caused by the disease was 20%～50% in irrigated field,and 10%～25% in nonirrigated farmland. The disease could be controlled by application of...

The Effecd of Temperature on Germination and Metabolism of Asparagus Seeds
Ren Anxiang;Zhou Qian;Wang Yumei et al.
   1997, 1 (1): 4-0.  
Abstract （1245）      PDF（pc） （108KB）（1043）       Save
The optimum germination temperatue of Asparagus seeds ranged from 20℃ to 25℃. The germination percentage of seeds,enzyme activity of α-amylase and respiratory intensity were positively related in a certain temperature range. The storage matters,such as starch,protein and fat etc. decreased while seeds germinated. The seed treatment of alternate temperature was better than the constant treatment. Temperature of day 25℃/night 20℃ gives the best result.

Effects of Night Temperature in Seedling Stage on the Occurence of Malformed Tomato Fruit
Li Tianlai;Wang Ping;Xu Hui et al.
   1997, 1 (2): 1-0.  
Abstract （1046）      PDF（pc） （392KB）（824）       Save
The results indicated that low night temperature in tomato seedling stage increased incidence,average grade and intergated index of malformed fruit,as well as the types of them. It was found that the critical temperature which induced high incidence of malformed fruit was between 6～12℃,the 10th～16th days after the two cotyledons fully expanded. The susceptible period for low temperature was at the stage of the 2nd～4th true leaves fully expanded. Therefore,tomato seedlings with 2～4 true leaves must be kept a...

Results obtained in pot culture experiment indicate that there was a remarkable linear correlation between phosphorus level and biological yield of garlic(Allium sativum)in brown-yellow soil(y=7.64+8.72x,r=0.950),the effect of adding P 2 O 5 500mg per kilogram soil was better. In the case of phosphorus deficiency,application of phosphorus promoted the absorption of nitrogen and potassium. Increased the concentrations of allicin and soluble sugar,and decreased the contents of vitamin c,calcium and m...

   1997, 1 (2): 3-0.  
Abstract （950）      PDF（pc） （187KB）（695）       Save
The path analysis in this paper showed that high CO 2 concentration of root zone under the plastic film mulch was the major factor which limited the activities of roots and leaves of tomatoes. Perforated film mulch improved soil aeration,decreased the CO 2 concentration of root zone,remarkably delayed senescence of the plants,accelerated the photosynthesis of leaves and supply capacity of roots,and eventually resulted in high early yield and total yield.

Ten important agronomic characters of 1192 accessions of yardlong bean(Vigna unguiculata ssp. sesquipadalis)genetic resources were investigated. Very high level of variance existed among these varieties for all the characters studied,including pod length,pod weight,pod shape,pod color and seed coat color etc. . And some special accessions,for example,erect bush types,extremely early maturity,long pods over 70cm,single pod weight over 25 grams,and 100 seed weight over 19 grams,were detected.
