三年试验表明,三十烷醇对高粱确有增产效应,不论是浸种处理还是不同生育期整株喷施,都可以提高高粱产量。三年产量经方差分析,初花期喷施和浸种处理与对照差异均达极显著水准;未花期和拔节期喷施与对照差异达显著水准。试验还表明,三十烷醇处理能引起高梁的多种生理效应。浸种处理可以提高种子萌发阶段的呼吸强度和过氧化物酶的活性,加速物质转化,促进苗期生长发育,形成壮苗。促进效应有不断的正反馈作用,并且能延续,使整个生育期的光合性能得到改善。不同生育期喷施三十烷醇,有提高叶面积;增加叶绿素含量;提高光合效率;延长叶片寿命;增长光合时间的效应。这些都是决定作物产量高低和光能利用率高低的关键。
Three years of experiments show that triacontanol does have a yield-increasing effect on sorghum. Whether it is soaking seed or spraying whole plants at different growth stages, sorghum yield can be increased. Three-year yield variance analysis, spraying at the first flowering and soaking treatment and control differences were reached significant levels; not flowering and jointing spraying and control differences were significant levels. Experiments also show that triacontanol treatment can cause a variety of physiological effects of sorghum. Soaking seed treatment can improve the respiration rate and peroxidase activity of seed germination stage, accelerate the material transformation, promote seedling growth and development, form strong seedlings. Promoting effect has a continuous positive feedback, and can continue, so that the whole growth period of photosynthetic properties are improved. Spraying triacontanol at different growth stages increased leaf area, increased chlorophyll content, increased photosynthetic efficiency, prolonged leaf life, and increased photosynthetic time. These are the key to determining crop yield and light energy utilization.
