摘要
温度对不同基因型大白菜花芽分化、抽薹开花等阶段发育都有不同程度的影响。供试大白菜品系春化17天后高温处理现蕾开花显著延迟,74天现蕾,较春化24天的材料延迟25天现蕾;10天以上的高温处理严重影响大白菜的阶段发育;1￣2叶龄的幼苗受高温影响最大。
Effects of temperature on floral bud differentiation, bolting and florescence were studied in Chinese cabbage. The date of budding and flowering was postponed evidently in all the materials vernalized for 17 days. In contrast to the materials vernalized for 24 days, the date of budding was postponed for 25 days, which were 74 days. The development and growth of Chinese cabbage were affected seriously by the high temperature treatment of more than 10 days. The seedling of 1-2 leafage was sensitivest to the high temperature.
