    摘要:

    野生大豆(G .Soja)是栽培大豆的近缘祖光种,利用中国野生大豆分布的广泛性,为我们了解和认识大豆在自然界中光温反应的规律提供了条件。通过对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的了解,明确了不同纬度区野生大豆在自然环境中出苗温度是13.1~14.7℃,开花期温度是20.5~26.5℃,成熟期温度是10~19℃;初花期临界光照时数是13h15min至16h40min之间。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化和成熟期越早。

    Abstract:

    Wild soybean(Glycine soja)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 was13.1-14.7℃,florescence temperature required 20.5-26.5℃,temperature for mature period required 10.0-19.0℃. The critical photoperiod for flowering was from 13 hours and 15 minutes to 16 hours and 40 minutes. 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.
