生健剂对玉米幼苗生长及生理特性的影响

Effect of Plant Robust Agent on Growth and Physiological Properties of Maize Seedling

采用室内生理检测及生物化学方法,研究了生健剂对玉米幼苗各生长时期及幼苗生理特性的影响。结果表明,用一定浓度的生健剂对玉米浸种和茎叶处理,对玉米幼苗的株高、根长、株鲜重和根鲜重有显著的影响,特别是对根鲜重的影响,促进率最高可达26%,同时增强了幼苗根系活力,最大可以提高85.2%,并且提高了叶绿素含量、超氧化物歧化酶、过氧化物酶和过氧化氢酶活性,这为生健剂在玉米田推广应用、提高玉米产量提供了重要理论依据。

The indoor physiological and biochemical detection methods were used in this study. During each growth period, the influence of different concentration of plant robust agent for the growth and physiological properties of maize were studied. The results suggested that the plant robust agent could increase the plant height, root length, plant fresh weight and root fresh weight, especially the influence on the root fresh weight, the promotion rate could reach 26% , as well as it could increase the activities of root, POD, SOD, CAT and content of chlorophyll, the promotion rate of activity of root could reach 85.2%. It supplied a theoretical basis for the plant robust agent widely applied in maize.
