  Microspore culture was carried out with 11 varieties of broccoli. Embryoids and regenerated plants were successfully obtained. The highest embryogenesis induction efficiency of 25. 28 per bud was achieved in luxiu. After treating the regenerated plants with 1 % colchicines, the chromosome doubling efficiency increased to 24%.

  Development process of tumorous stem characters were studied by using a mustard variety Fuza No. 1 sown on Aug 30 and Sep 9. The results showed that the development processes of vertical diameter, horizontal diameter,fresh weight and dry weight could be described by Logistic equation y= k(1+ e(a+bt))-1 and the tumorous stem index met the type of regression curve y=a+b1t+b2t2. The beginning of linear-growth period of vertical diameter,horizontal diameter,dry weight and fresh weight were 2.1-9.6 days, 17.8-19...

  Effects of grafting on growth and development, yield and quality of muskmelon in solar-greenhouse were studied. The result indicated that the plant height, the number of leaves, the rate of fruit enlarging and yield were increased by grafting. There was no obvious effect on the appearance of fruit, but the soluble solid and VC contents and the number of female flowers in lateral branch were decreased by grafting.

  293 isolates were obtained from rhizosphere soil of pepper. It was found that 5 potential biocontrol spore bacteria showed good antagonistic action on Phytophthora capsici by pairing culture on CAA. The inhibition zone diameter ranged from 8.0 mm to 11.3 mm. The result from the experiment at greenhouse showed that Bn - 130 isolate could effectively control the pepper blight, and the control efficiency reached 64. 7 %. The culture filtrate of Bn - 130 isolate was effective for inhibiting mycelium growth and ...
