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 pleasant winter short-day crop, photoperiod and temperature on the growth and development of different ecological types of soybean varieties are different. Under natural conditions, the early-maturing soybean variety Hefeng 42 was sowed in three different locations to study the effects of different light and temperature on soybean growth, morphological traits and yield-related traits, and to further explore the effects of light and temperature The mechanism of early-maturing soybean provides a theoretical basis for early-maturing soybean ecological breeding. The results showed that the growth process, agronomic traits and yield traits of Hefeng 42 were affected by light temperature and temperature.
