大豆生态研究 Ⅹ.光温综合作用与野生大豆（G.Soja）种群生态研究

STUDY ON SOYBEAN ECOLOGY Ⅹ. COMPREHENSIVE EFFECT OF LIGHT AND TEMPERATURE AND POPULATION ECOLOGY OF WILD SOYBEAN (G. Soja)

摘要:

①野生大豆(G.Soja)长期在原产地自然条件下，自生自长，达到自然开花临界光周期而开花，达到临界温度而停止复叶发生，反应了野生大豆的种性。②分枝按各自出现后的光温动态完成各自的生育过程。分枝的出现期可看作分枝的出苗期，每一个分枝是独立个体，分枝的综合体可看作是群体。③叶片感光效应与生长期间的光温动态及自然开花临界光周期三者之间的综合作用，是野生大豆种群生态的理论依据。

Abstract:

1. wild soybeans grow naturally under the trend of light and temperature at their origination, and form natural flowering critical photoperiod, natural critical temperature and the regular pattern of growth and development.This reflects the species character of wild soybean. 2. Each branch can be regarded as an independent individual, the time of appearence can be regarded as the emergence time of branch, and the course of its growth and development is completed according to the trend of light and temperature after its appearence.3. The comprehensive effect of light and temperature between the responsibility to photoperiod of leaves and trend of light and temperature, natural flowering critical photoperiod,natural critical temperature is the theoretical basis of population eeology of wild soybean.
