摘要：

以2个籼稻品种II优航1号、扬稻6号为材料，研究了齐穗后去除顶穗和保留顶穗对倒2节间叶腋内休眠分蘖芽(倒2芽)的生长动态及倒2芽、倒2芽着生节(倒2节)中内源激素(IAA、Z+ZR、ABA)含量的影响。结果表明，去除顶穗后，倒2芽休眠解除，开始萌发生长。在去除顶穗后1 d内，倒2节中吲哚-3-乙酸(IAA)水平、倒2芽中脱落酸(ABA)水平迅速下降，其后2种激素含量基本保持稳定，而留穗处理这2种激素含量变化不大。去除顶穗后，倒2节和倒2芽中玉米素+玉米素核苷(Z+ZR)含量均持续升高，与留穗处理间的差异不断扩大，其变化动态与倒2芽生长动态相一致。而2个处理间倒2节中ABA水平、倒2芽中IAA水平相差不大。分蘖芽的萌发生长是多种激素共同作用的结果，芽中较低的ABA/(Z+ZR)值、节中较低的IAA/(Z+ZR)值有利于分蘖芽的生长，其值较高抑制分蘖芽生长。

Abstract:

Tiller number is a major factor affecting rice grain yield. The endogenous hormone has substantial regulative effect on tillering of rice. However, little is known on the hormonal changes in releasing tillering bud. In this study, two indica rice cultivars were used with two treatments, removing panicle and retaining panicle, to investigate the pattern of hormonal changes during the period of dormant tillering bud sprouting. The result showed that the dormant tillering bud released and grew quickly after panicle removing. 1 d after removing panicle, the level of IAA in node and level of ABA in tillering bud decreased significantly, then the contents of these two hormones maintained at a constant level. The contents of Z+ZR in both node and bud increased significantly in panicle removing treatment. However, the content of IAA in the bud and the content of ABA in the node showed no significant difference between the two treatments. Further, the results showed that the ratio of hormones rather than a single hormone has the larger impact on tillering bud growth, with lower values of ABA/(Z+ZR) in bud and IAA/(Z+ZR) ratio in node showing beneficial effect whereas higher values of the two ratios demonstrating deleterious effect on tillering bud growth.
