摘　　要：野生大豆是栽培大豆的近缘祖先种。中国野生大豆分布的广泛性,为了解和认识大豆在自然界中光温反应的规律提供了条件。利用29个纬度区自然生长的野生大豆主要生育阶段光温反应特点,明确了不同纬度区野生大豆在自然环境中出苗温度为13.1～14.7℃,开花期温度为20.5～26.5℃,成熟期温度为10～19℃;初花期临界光照时数为13.25～16.67h。出苗越早的低纬度区野生大豆开花和成熟期越晚,而出苗越晚的高纬度区野生大豆开花和成熟期越早。Wild soybean is distributed widely in China. providing us enough characteristics appearances to realize the regularity of wild soybean in natural environment. According to the investigation of photoperiod and temperature effects on different developing stages of wild soybeans growing naturally from 29 latitude areas, we recognized that,in natural conditions,the germination temperature for soybean was 13.1 -14.7℃, florescence temperature required 20.5 -26.5℃ , temperature for mature period required 10.0 - 19.0℃. The critical photoperiod for flowering was from 13.25 hours to 16.67 hours. For the seeds from low latitude areas, the earlier they germinated, the later they would flower and mature. For the seeds from high attitude areas., the later they germinated, the earlier they would flower and mature.
