摘要
大豆是喜温短日照作物,光周期和温度对不同生态类型大豆品种生长发育的影响不同。在自然条件下,对早熟大豆品种合丰42号分别在3个不同地点进行分期播种,研究不同光温生态条件对大豆生育进程、形态性状、产量相关性状的影响,并进一步探讨光温效应对早熟大豆的影响机制,为早熟大豆生态育种提供理论依据。结果表明,合丰42号的生育进程、农艺性状和产量性状都受光温效应的影响。
Soybean is a high temperature and short-day crop. Soybean shows different developmental stage in different eco-region. In order to analyze the growth process, morphological traits, yield and yield-related traits change, and to further explore the effects of light and temperature on soybean development, the soybean variety Hefeng 42 was planted in different locations with vary staging, light and temperature conditions under natural conditions. The results showed that the growth process of soybean variety Hefeng 42, agronomic traits and yield traits were affected by the change of light and temperature.
