摘　　要：１２０～１５０ＰＰｍＴＭ处理，促进大麦幼苗分蘖，在拔节期、孕穗期控制大麦植株生长，使植株基部第１节、第２节缩短，在一定程度上增强了植株抗倒能力。而且，ＴＭ使每穗实粒数增加，空粒数减少。１４Ｃ－萄葡糖示踪试验表明，在大麦乳熟中期，１２０ｐｐｍＴＭ能提高灌浆强度。ppm TM treatment on barley at the tiller stage had effects of enhancing tiller ofseedling,controlling the elongation growth of plant at jointing and booting stages and reduc-ing the internode length of the basal stem and 2nd from the basal stem,hereby increased theability of lodging resistance.In addition,TM inereased the number of grains,reduced thenumber of blighted grains with no 1000 grains weight decrease.The results from the test of 14C-gluose trace showed that TM enhanced the intensity of milky at the milky stage.
