关于甜菜的发育机理,我国自五十年代直至最近所发表的大部分文章中,多是引用了苏联书刊上报导的通过“春化阶段”、“光照阶段”的具体数据,以及“只有通过春化阶段后才能通过光照阶段”,发育是“不可逆的”等理论。但是在近几年,我国一些科研和生产单位所进行的有关甜菜发育控制技术和南方繁种的试验研究中,出现了不少用上述植物阶段发育学说无法进行解释的现象。如在我们前几年的研究中,就发现了甜菜不仅可以先经过冬季低温及翌年初夏长光照而抽苔开花,而且可以在苗期同时感
As for the development mechanism of beet, the majority of articles published in our country from the 1950s up to recently quoted mostly the specific data passed through the “vernalization stage” and “light stage” reported in the Soviet Union and the “ After the stage can pass the illumination stage ”, development is“ irreversible ”and other theories. However, in recent years, some research and production units in our country have conducted experiments on the control technology of sugarbeet development and breeding in the south, and many phenomena that can not be explained by the above-mentioned plant stage developmental theory appear. As we studied in previous years, we found that sugar beet can not only be planted and flowered through the winter low temperature and the early summer light of the following year, but also the seedling
