摘要
对植物生长延缓剂和修剪处理下多年生黑麦草的抗旱性进行研究。结果表明:在干旱胁迫的各个阶段,留茬6cm处理叶片含水量和游离脯氨酸含量显著高于其他处理。各延缓剂处理下的叶片含水量和游离脯氨酸含量均高于对照,可显著增强多年生黑麦草的抗旱性。
Drought resistance of Lolium Perenne (Perennial Ryegrass)which treated by plant growth retardants and mowing was studied.The results were as follows :The relative water content (RWC )and praline of6cm stubble treatment of perennial ryegrass were higher than that of4cm and6cm stubble treatment.The relative water content (RWC )and praline,which treated by plant growth retardants,were significantly higher than that of the control.So plant growth retardant treatments increased drought resistance of Lolium Preened.
