摘要
以梨为试材 ,对成花过程中CaM和核酸的含量进行了分析测定 ,结果表明 :短枝芽的CaM含量在成花的发端期成倍增加形成高峰 ,而新梢芽却一直保持较低的水平 ;短果枝叶的CaM与新梢叶有着相近的变化趋势 ,但在成花前后 ,短果枝叶的CaM含量要明显高于新梢叶的 ;短枝芽所含核酸、尤其是RNA开始回升时与CaM的峰值相吻合 ,并且在整个成花期间都呈上升的趋势。
Experiments were carried out by using pear as the material to measure and analyse the content of calmodulin (CaM) and nuclear acid (NA) in the process of flower differentiation. The results showed that CaM in the buds on spurs increased to form a peak in flower initiation, whereas CaM in the buds on shoots was maintained at a relatively low level. the change in CaM in leaves on spurs was similar to that on shoots, but the former was obviously higher than the latter before and after flower differentiation. NA, especially RNA, in the buds on spurs had the correspondent peak with CaM when it began to rise. During the whole process NA had the upward tendency. Relationship and functions of CaM and NA during flower differentiation were also discussed herein.
