一.阶段发育是植物发展的自然规律植物的形成与进化和外界环境条件有着不可分割的联系,这种联系是自然长期选择的结果。因此植物对於曾经产生它的环境条件,就成为了它生活中的要求,由於植物与环境是一个统一的关系,因而植物在其发育过程中对於一定环境条件的要求,必然是其历史形成的反映。李森科关於植物阶段发育理论的概念是从冬小麦的研究中总结出来的,具体的反映了冬小麦的历史形成与环境条件的关系,冬小麦对於低温条件及长日照条件要求的这种严格性,并
I. Stages of development are the natural laws of plant development The formation and evolution of plants and the external environmental conditions are inextricably linked. This connection is the result of long-term natural selection. Therefore, the plants have become the requirements of their life for the environmental conditions that once gave birth to them. Since plants and the environment are in a unified relationship, the requirements of the plants for certain environmental conditions in their development are necessarily formed by their history The reflection. Lysenko’s concept of plant stage developmental theory is summarized from the study of winter wheat and specifically reflects the relationship between the historical formation of winter wheat and environmental conditions and the stringency of winter wheat for both low temperature and long daylight conditions and
