大白菜产量形成及其与各类型叶生长速率相关性的研究

Study on the relativity between Chinese cabbage output formation and growth rate of diferent leaves

大白菜的生长可按其生长速率分为三个阶段。大白菜单株重与其第三个生长阶段的生长速率显著相关 ,同时 ,还与幼苗叶重量下降阶段的生长速率、莲座叶重量增加阶段的生长速率 ,以及球叶的生长速率显著相关。

The growth process of Chinese cabbage can be divided into three period according to its growth rate Chinese cabbages individual weight is remarkably correlated to its growth rate during the third period,to the positive growth rate of juvanile leaf and rosette leaf,to the growth rate of heading leaf
