一、小麦对温光反应的性质二、小麦的光周期效应 (一)小麦光周期反应的性质 (以上见本刊1984年第五期) (二)光周期反应的始末期及其对发育的影响小麦具备光周期反应能力的早晚,不同品种间差异很大。有人从发芽中的胚开始进行处理,发现胚和胚芽鞘对光周期无反应。最早具 First, the nature of wheat response to temperature and light Second, the photoperiodic effect of wheat (A) the nature of the photoperiodic response of wheat (see above, 1984 fifth issue) (B) the beginning and end of photoperiodic response and its development Sooner or later affect the ability of wheat to have the photoperiod response, and there are great differences among different varieties. Someone started to process germinated embryos and found that embryos and coleoptiles did not respond to photoperiod. The earliest
