摘要：研究了叶面喷施几种植物生长调节剂(GA3、NBT、6-BA、TIBA、PP333)对小麦分蘖、生育后期生理指标、产量构成因素和产量的影响。结果表明:合理的使用这些植物生长调节剂可以不同方式影响冬前小麦的分蘖能力,提高生育后期叶细胞的自我保护能力、光合能力及对有机物的利用和转运能力,延长了叶片的功能期,有利于籽粒灌浆,并能较好的协调产量构成因素的关系,提高作物产量,总体效果看:PP333和6-BA综合效果较理想;TIBA对提高千粒重有显著作用。
Effects of applying plant growth regulators on winter wheat were studied during 2000 - 2002. The results showed that applying GA3、NBT、6 - BA、TIBA and PP333 appropriately could affect tiller in the vegetative growth stage, keep the NR and SOD activity at high level, increase the content of soluble protein and total chlorophyll in the later stage. They could imrove the photosynthetic capacity, promote assimilation product transport and accumulation during grain filling period of wheat. They delayed the senescence of functional leaves, had the positive effect of grain filling, form the good relationship of yield constituents and increase the yield. But each of them worked in different way.
