STUDY ON SOYBEAN ECOLOGY- VIII RELATIONSHIP BETWEEN THE COMPREHENSIVE EFFECT OF PHOTOPERIOD AND TEMPERATURE AND REPRODUCTIVE GROWTH OF WILD SOYBEAN (GLYCINE SOJA)

Wild soybean(G.soja) emerges normally under natural conditions at their origination.During the stages of vegetative and reproductive growth,leaf responsibility to photoperiod promotes vegetative growth while air temperature goes up;on the contary,reproductive growth is promoted.The responsibility to photoperiod of unrolled leaf leads to the occurance of primary inflorescence,and that of leaf fell into a pattern leads to the occurance of secondary inflorescence.In this paper the relations between the comprehensive effect of photoperiod and temperature and the course of flower and pod formation were discussed.
