  A new spring cabbage F1 hybrid─ Chunbao , was bred by crossing two self-incompatible lines of 441591 and 87123. It has pointed head, early maturity, tolerance to bolting, high yield and good quality. It is 3～ 5 days earlier and 60% higher in yield than that of Niuxin (the popular cultivar).The average yield is 30～ 52.5t/ ha and has been grown in region of Yangtze River over 2000 ha.

  In two parthenocarpic lines Severianin (pat-2/pat-2), Monalbo (pat-2/ pat-2) and one isogenic line of Monalbo (+/+) without pat-2 gene fruit set percent (FSP), fruit weight (FW), seed productivity (SP) and single plant yield(SPY) were investigated after 4 different pollination treatments. The two parthenocarpic lines could set fruit and the fruits normally developed even without pollination but non-pathenocarpic line could not if no pollination performed. SP of parthenocarpic line was much lower than that o...

  When eggplant seedlings were raised in mixed media (peat, vermiculite and cinder), the plant growth, dry matter accumulation and uptake amount of nitrogen, phosphorus and potassium increased with fertilizer application levels. The plant height, dry matter accumulation and uptake amount of nitrogen, phosphorus and potassium were nearly maximum when the fertilizer application level reached 2800g /m￣3.Therefore, 2800g/m￣3 was optimum for raising seedlings with mixed media.

  Chinese cabbage (87-3) seeds, with five levels of moisture content 5%～1 %.were stored for three years in four temperature (-20℃, 4℃, room temperature, 40℃ )respectively and their viability were measured in this experiment. The result is summarized as follows: Seeds viability stored in room temperature is the same as those in -20℃ and 4℃, but viability of seeds stored in 40℃ reduced significantly. Viabilities of Chinese cabbage seeds haven t changed after they were treated with ultra-drying and stored in roo...
