由于苏联学者的研究,指出了流入茎生长点的营养物质对植物的阶段发育有很大的意义。此等营养物质,其性质随植物的阶段发育而有所不同。阿瓦江院士一系列的试验说明了,在春化阶段的营养物质,只有在为植物本性严格要求下一定的低温下形成,而在光照阶段,则由于绿色叶片在本性要求下一定长度的白天与黑暗的循环下始能形成。由于对营养物质与阶段发育的关系的进一步探索,苏联学者发现:为某一植物发育阶段所特殊要求的营养物质的分量,强烈地影响着阶段发育的过程的速度,适当的调节营养物质,使 Due to the research of Soviet scholars, it is pointed out that the nutrients that flow into the stem growing point are of great significance to the stage development of plants. The nature of these nutrients varies with the stage of the plant. A series of experiments by the academician of Awawa indicated that the nutrients in the vernalization stage are only formed under a certain low temperature under the strict requirements of plant nature. In the light stage, due to the nature of the green leaves during a certain length of day With the beginning of the dark cycle can form. As a result of further exploration of the relationship between nutrients and stage development, Soviet scholars found that the amount of nutrients required for a particular stage of plant development strongly influences the rate of stage development and the proper regulation of nutrients
