植物开花机理,长时期以来,一直是植物生理学界所探讨的主要问题之一。对于甜菜的开花机理,国内外都作过一些试验,并有着不同的看法。但50年代以来,在我国书刊上所发表的有关著作中,多数是引用了苏联人在40年代根据“阶段发育”学说提出的甜菜发育条件。可是在70年代,我国一些单位进行的有关甜菜开花控制技术和南方繁种的研究中,所出现的许多现象,都是引用“阶段发育”的理论和条件所无法解释的。因此,我们以甜菜育种过程中的实际应用为目的,对甜菜抽苔开花的环境条件和控制技术,进行了一些试验和验证工作。本文主要根据1972～1980年间所进行的各项试验结果和有关资料,对甜莱的抽苔和开花问题,提出一些初步认识。
Plant flowering mechanism, for a long time, has been one of the main problems discussed by plant physiology. For the beet blossom mechanism, both at home and abroad have made some experiments, and have different views. However, since the 1950s, most of the books published in the Chinese journals have quoted the development conditions of the beet developed by the Soviet Union in the 1940s on the basis of the theory of “stage development.” However, in the 1970s, many of the phenomena that occurred in the research on sugar beet flowering control technology and breeding in the south conducted by some units in our country could not be explained by reference to the theory and conditions of “stage development.” Therefore, for the purpose of practical application in the process of beet breeding, some experiments and verifications were carried out on the environmental conditions and control techniques of beet bolting and flowering. In this paper, based on the results of the tests carried out between 1972 and 1980 and the relevant data, some preliminary understandings on the bolting and flowering of sweet potatoes were put forward.
