中国大豆地理生态型生育前期短光照反应

Response to Short Photoperiod of Days to Flowering of Soybean Ecotypes of China

将我国大豆各地理生态型代表性地方品种256份,在南京春播进行11h短光照处理,以大豆品种南京春播自然光照与11h短光照下生育前期相差天数为生育前期短光照反应强度的指标,比较我国不同大豆地理生态型生育前期短光照反应及品种间变异。

A total of 256 varieties of different ecotypes of soybeans from China were seeded under natural photoperiod or 11h photoperiod in spring in order to exhibit the difference of responses to short photoperiod of days to flowering of soybean ecotypes. The response of each soybean was showed by its diviation of days to flowering under natural photoperiod and 11h photoperiod. This paper was aimed at the comparison among ecotypes on basis of the responses of days to flowering.
