| 摘 要： | 多效唑对大麦生长发育及产量品质的影响试验中,多效唑处理生育时期和生育期无明显差异;有效穗随着浓度的增加略有下降的趋势;多效唑有降低株高的作用;低浓度有增加有效分蘖数的作用;穗粒数除300mg/kg处理略低于对照以外,其于处理均高于对照,表明多效唑有一定的增粒效果;不同浓度多效唑处理具有增加单穗重的效果;不同浓度多效唑处理具有增加千粒重的作用。经方差分析处理间产量差异不显著。

| Abstract: | The experiment result of effects of paclohutrazol on the growth, yield and quality of barley shows： There is no obvious differences on the period of growth to treatment of growth stages; Effective panicles have a down ward trend with increasing the concentration; And paclobutrazol may reduce the plant height; The low concentration of paclobutrazol increases the number of effective tiller; The grain number of spike of treatments are all higher than that of control group besides the treatment 300mg/kg, and shows the paclobutrazol may increase the grain number of spike. The treatment with different concentrations of paclobutrazol can increase single-spike weight and 1000-grain weight. There is no significant differences between treatments by analysis of variance in yield. |
