大豆是一种比较典型的短日性植物,在其由营养生长转向生殖生长的过程中,与光照长度有着密切的关系。关于大豆结实器官的发生和发育与光照长度的关系,国内及国外的许多学者曾经进行了很多的研究。证明了大豆由营养生长转向生殖需要满足其一定的短日照要求,否则就会阻碍发育的速度,或者使其停留在营养生长状态。同时也指出了,在一定的光照长度下和不同光暗周 Soybean is a typical short-term plants, in its process of vegetative growth to reproductive growth, and the length of the light has a close relationship. With regard to the relationship between the occurrence and development of solid-borne soybean organs and light length, many scholars both at home and abroad have conducted many studies. It is proved that soybean needs to meet some short daylight requirements from vegetative growth to reproductive needs, otherwise it will hinder the development speed or make it stay in vegetative growth state. Also pointed out that, in a certain light length and different light dark week
