Study on the Cause Mechanism for Pods without Peas in Soybean under Drought Stress

doi:10.3321/j.issn:1000-7091.2005.05.015

Abstract

Abstract: Under the manned simulation of drought,the rate of seedless pods has increased during soybean's every vegetative period.The production sinks down obviously.The highest rate of seedless pods is found from pod bearing period to seed inflating period.Drought stress weakens plant water potential and photosynthesis,lowers the helpful enzymes activity,blocks the development of root system and absorption of nourishment.All of the above factors constrain plant growth greatly.

Key words: Drought stress, Summer soybean, Pods without peas, Cause mechanism
