  The effects of storage temperatures on the qualities of broccoli ( Brassica oleracea. var. italica P.) packaged with 0.03mm PE were studied. The results showed that the senescence of broccoli stored at 16℃ was very fast;the content of total soluble protein,total acids,vitamin C and chlorophyll decreased rapidly;on the 3rd day of storage,the yellowing rate was 5.0%,weight loss was 12.2% and the broccoli almost lost eating quality. However,the senescence of broccoli stored at 0℃ and 5℃ was delayed ...

  The experiment showed that the temperature was significant influence on the life cycle of Li riomyza sativae Blanchard,but the humidity was not. The relationship between the development rate and the temperature accorded with logistic curve. The developmental zero temperatures of eggs,larvae,pupae and the whole generation were 10.01,9.7,10.2 and 9.76℃ with the effective accumulated temperatures were 65.26,80.7,147.96 and 298.33℃,respectively. The most suitable temperature and humidity for survival o...

  A cultivated eggplant variety Qiyeqie as scion was grafted on 5 wild Solanum species as rootstock respectively. The effects of graft on resistance to Verticillium dahliae and on biological characteristics of eggplant were studied. The results demonstrated that there was high affinity between every rootstock of 5 wild species and scion,all the survival rate of grafted plant was above 95%. It also indicated that the grafted plants were better not only in root system,diameter of stem and leaf,plant hei...
