Abstract:

Planting dates influence fresh pod yield and quality in vegetable soybean.Preliminary test was conducted in 2010 which vegetable soybean CAS 1 was grown at 4 planting dates (May 3, May 15, May 27 and Jun 8) in field condition.And then three vegetable soybean cultivars with different soluble sugar contents were grown at 4 planting dates in field condition in 2011. The activities of sucrose phosphate synthase (SPS), sucrose phosphate synthase (SPS), acid invertase (AI) and neutral invertase (NI) from fresh green seeds harvested at the R6 stage were analyzed.Similar responses of SPS and SS activities in different cultivars were observed to planting dates. With the delayed planting, the activities of the two enzymes were significantly reduced. The SPS activities in the early planting date of May 3 were 10.8%-27.7% greater than late plantings, while the SS activities were 4.8%-17.4% greater. The change of AI activities by delayed planting was not obvious. NI activities were also reduced by delayed planting but with less extent.The alteration in the balance of SPS, SS, AI and NI by delayed planting might be the inherent physiological mechanism responsible for the reduction of sucrose accumulation in vegetable soybean
