  Experiment on effects of fertilizer application in protected tomato cultivation on the changes of the contents of soil nutrients and soil salinity under various fertilization models were conducted in the autumn of 2000 and the spring of 2001. The results showed that the application of N at rate of 225 kg·hm -2 with sheep waste at 26.2 t·hm -2 reached the highest yield, but the economically optimum application rate should be below 225 kg·hm -2. Over application of N from urea enhanced water soluble ...

  Based on the multiple allele hypothesis,the male sterile lines 98109 and fertile plant 99135-2 of AB lines type Ⅰ of Chinese cabbage were used as a source of male sterility,the inbred line 97A407 as goal parent. The gene of male sterility was transferred to 97A407. New AB line type Ⅰ,new male sterile line and their corresponding temporary maintainer line were abtained from transferred progenies deprived from 97A407. It promotes the breeding of F 1 hybrid of Chinese cabbage.

  The paper dealt with the storage effect of different moisture contents on kidney bean seeds. Seeds were dried by desiccant CaCl 2 to 3 moisture levels (7.44%,5.56% and 4.55%) respectively. Germination percentage,vigor index,conductivity,superoxide dismutase activity and aging test were measured every three months. After one year the results showed that kidney bean seeds viability and vigor decreased significantly at 5.56% and 4.55% MC, while those of seed with 7.44% MC were kept well. Seeds with lower tha...
