土壤加温(30℃)对大白菜抽苔的影响试验研究是在控温生长房内进行的。两次试验的结果指出,根系加温对春化作用没有影响。但是,根系加温可以通过热向生长点扩散而降低春化效应。如果进行地面隔热覆盖或缩短下胚轴都会促进根热向生长点传导。通常认为,对需要春化的植物来说,生长点是接受春化作用的部位。已有几种作物如芹菜、甜菜、菊花的试验结果支持这一说法。但在从植物的某些部位做试验结果指出,组织,例如根就可以接受春化作用。即使是一棵完整的植株,根对春化作用也会育影响,他们利用大白菜做过试验。要获得更多有关花的诱导机制的资料,有必要 Effects of Soil Warming (30 ° C) on Bolting of Chinese Cabbage The experimental study was conducted in a temperature controlled growth chamber. The results of the two experiments indicate that root warming has no effect on vernalization. However, root warming can reduce the vernalization effect by spreading heat to the growing point. If the ground insulation cover or shorten the hypocotyl will promote the root heat conduction to the growth point. It is generally accepted that for plants in need of vernalization, the point of growth is the site of vernalization. Several studies have been supported by the experimental results of several crops such as celery, sugar beet and chrysanthemum. However, in some parts of the plant test results indicate that the organization, such as roots can accept vernalization. Even an intact plant will have a fertile effect on vernalization, and they tested it with Chinese cabbage. It is necessary to obtain more information on flower induction mechanisms
