  A new pickling cucumber line 7012A was developed through interspecific hybridization of cultivated cucumber Beijingjietou with the Cucumis wild species C. hystrix and subsequent backcrossing of the hybrid to cucumber and selection from the selfed progenies. This line was used to cross with an elite American pickling cucumber line (7011A) from the University of Wisconsin to produce F 1. The results indicated that the F 1 has significant heterosis over its parents in yield and growth vigor. The plants ...

  The effects of different temperature during daytime(25 ℃, 30 ℃, 35 ℃)on photosynthesis and carbon accumulation and distribution of tomato in greenhouse were studied. The results showed as follows, sub-high temperature decreased the chlorophyll and photosynthesis of tomato and made the growth of plant worse than control. Sub-high temperature advanced the development of fruits, and shorted the time of maturation. The carbon accumulation and distribution of tomato under sub-high temperature were changed as wel...

  The effect of different varieties and culture conditions on allicin content in garlic bulb was studied. The results showed that the allicin contents of different varieties were significant. The density, the relative content of water, soil type and the harvesting date influenced the allicin content in garlic bulb. The suitable density was 525 000 plants per hm 2; the suitable relative content of water in soil was 40 %; the suitable sand content in the soil was 87.35 %; the suitable harvesting date was 21 day...

  Both foliar spray in laboratory and field trails were conducted to evaluate the effect of thiamethoxam 25 % WG against adults of Bemisia tabaci B-biotype on cucumber seedlings. The laboratory bioassay indicated that the activity of thiamethoxam was 290-fold as much as chlopyrifos, and the results in field trials showed that the controlling effects reached 95.39 % in 3 days. The suitable dosage concentration was 1∶5 000-6 000 dilution for foliar spray.
