项目摘要

It is well known that conversion of growth phase, from vegetative growth to reproductive one, is mainly dependent on day length and temperature in their growing period. Recently, it is clear that the same plant has a different time to develop young panicle in their individual tillers. In an investigation of leaf emergence and heading date, results obtained were as follows :1.Leaves on individual tillers expanded in regular sequence of synchronous leaf growth theory by 'Katayama'. Primary tillers had one more leaf than that of main stem, and secondary tillers had also one more leaf than that of primary tillers.2.Primary tillers which originated from 6 - 8th node on main stem showed short intervals of their leaves expansion and earlier heading.3.Primary tillers emerged from lower node on main stem headed later than that of 6 - 8th tillers. As this was observed in direct seeding plant, it is considered that above tendency may be inherent properties in rice plants.4.When the leaves of primary tillers from every even numbered nodes on main stem were cut at the end of their expansion, even numbered primary tillers showed late heading. Whereas, odd numbered primary tillers which had intact leaves, did not show any influence in heading.5.Gibberellic acid, injected by syringe to the vein of main stem leaf, elongated upper internode of treated leaf. While, their tillers did not respond at all. These suggests that individual tillers on a plant were independent as to their growth.6.In barley and wheat, heading data of primary tillers delayd as the node position of primary tillers proceed upwards.

众所周知，从营养生长到生殖阶段的生长阶段的转化主要取决于其生长期的日长度和温度。最近，很明显，同一植物有不同的时间在其个体分ers中发展年轻的锅胶。在对叶片出现和标题日期的调查中，获得的结果如下：1。单个分ers的叶子以“ katayama”为常规的同步叶片生长理论序列扩展。初级分ers比主茎的叶子多，次要分ers的叶子也比原发性分erer的叶子多。2。主要茎上的6-8个节点的主要分ers显示出短的叶子膨胀间隔，并且较早的标题。3。primary tillers从主茎的低点出现在主茎上的较低的茎上，比6-8th thters thters therers therers therers therers therers therers。正如在直接播种厂中观察到的那样，被认为以上趋势可能是水稻植物中的固有特性。4。在膨胀末端的每个偶数淋巴结中的原发性分ers的叶子在其扩张结束时切开时，即使是编号的初级分ers也显示出较晚的标题。而奇怪的原发性分ers的叶子完整的叶子在标题中没有显示出任何影响。5.GibberellicAcid，由注射器注射到主茎叶的静脉中，是处理后叶片的上部节节节。而他们的耕种者根本没有回应。这些表明，工厂上的个体分ers在其生长方面是独立的。6。在大麦和小麦中，随着初级分ers的节点位置向上进行，主要分ers的数据延迟了。
