大豆生态研究 Ⅶ.光温综合作用与野生大豆（G.Soja）生殖生长关系的研究

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

摘要:

野生大豆(G.Soja)在原产地自然光温条件下，正常期出苗，营养和生殖生长阶段，气温升高，叶片感光效应反应促进营养生长；气温下降，叶片感光效应反应抑制营养生长而促进本节生殖生长。展开叶感光效应发生初生花序，定形时感光效应发生次生花序。还提出了光温综合作用与花荚形成的过程。

Abstract:

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.
