不同植物生长调节物质对玉米根系衰老及产量的影响
Effects of Different Plant Growth Regulators on Decrepitude Index of Root System and Yield of Maize
摘要
Abstract
In order to investigate the effects of different plant growth regulators on the roots decrepitude and yield of maize, the roots growth,activity and antioxidant system and its yield of Zhengdan 958 were studied with seven plant growth regulators seed dressing in pot and field experiment. The results showed that the root quantity increased, the activity of root tip and its antioxidant enzyme were inhanced after treatment of seven kinds of regulators , which resulted in delay of the decrepitude of root, and also the effects of compound regulators were more significant than single regulator. Among the different regulators, the regulative effects of E were most obvious which the yield of maize was improved by 9. 93% compared with control. The experiments show that there are significant regulative effects of seven kinds of regulators on the decrepitude of roots and yield, especially E which is a compound regulator in maize production is a feasible technology means.关键词
