不同浓度芸苔素内酯对夏玉米植株性状及产量的影响
Effects of Different Concentrations of Brassinolide on Plant Traits and Yield of Summer Maize
摘要
Abstract
The effects of spraying different concentrations of brassinolide at seedling stage and trumpet shaped stage on plant traits and yield of a summer maize variety’Jinke25’under normal low planting density were studied in this paper.The results indicated that the yield components such as grain number per row,air dry weight of ear,air dry weight of grain,1 000-grain weight and yield significantly increased after applied with 50 mg/kg concentration of brassinolide,and yield increased 17.98% than the control,which provided basis for enhancing population yield through enhancing individual plant yield under low planting densities.However,it was also found that the effects of brassinolide on lodging resistance traits such as plant height,ear height and stem diameter were not significant.Our results could supply scientific data and technological direction for the practical application of brassinolide.关键词
