我们在1949年开始研究,决定在阶段发育理论的基础上阐明:小穗突起是在光照阶段开始时形成还是在通过光照阶段的时期内形成的呢?或者是在生长点内发生那些质变的基础上形成的呢?研究是在季米里亚捷夫农学院选种遗传试验站人工气候实验室和苏联科学院遗传研究所进行的。试验是布置在温室或大田的条件下。研究的对象是春小麦、冬小麦、冬黑麦和多年生牧草。第一个试验的观察证明春小麦莫斯金布布里特48的植株:在普通的日照下,幼苗出现後经过12天,生长点开始分化,在连续光照下是经过9天。在短日照下(9小时),于试验进行的全部时期内,生长点几乎是没有明显地形态变异。当处在人工连续光照下的植株开始抽穗的时候,短日照的一部分植株(生长点没有分化的)被移植到普通的日照条件下,而另一部分植株移植到人工连续光照下。生长点发育的观察
We started our study in 1949, deciding on the basis of staged developmental theories to clarify whether spikelet processes were formed at the beginning of the light stage or during the light stage, or at the point of growth The study was carried out at the Genetic Experiment Station of the Gemry Agricultures Genetic Selection Station and the Institute of Genetics at the Soviet Academy of Sciences. The test is placed in the greenhouse or field conditions. The research object is spring wheat, winter wheat, winter rye and perennial grass. Observation of the first experiment demonstrated that the plants of the spring wheat Moschinobu Breit 48: under ordinary sunlight, after 12 days after emergence of the seedlings, the growth point began to differentiate, and in continuous light, 9 days passed. Under short daylight (9 hours), there was almost no significant morphological variation of growth points during the entire period of the experiment. When plants under artificial continuous lighting started heading, some of the plants in short-day (undifferentiated growth points) were transplanted to normal sunlight while the other part was transplanted into artificial continuous light.
