摘　　要：探讨了植物生长延缓剂对暖季型草坪草细叶结缕草冬季生长和抗寒性的影响。结果表明,适宜浓度的多效唑和烯效唑可延缓植株生长,提高叶绿素水平,增加叶片的可溶性糖和可溶性蛋白质含量,促进抗氧化酶活性,增强细胞的活性氧清除能力,降低质膜相对透性,从而有助于提高草坪草的抗寒能力,解决细叶结缕草冬季枯黄的问题。The effects of plant growth retardants on the growth and coldresistance of Zoysia tenuifolla in winter were studied The results showed that paclobutrazol and uniconazole in right concentrations could retard plant growth, increase chlorophyll concentration, promote the contents of soluble tangar and soluble proteins in leaves, stimulate the activities of antioxidation enzymes, enhance the decomposing capacity of activated oxygen, reduce the relative plasmalema permeability as well Therefore it could be solve the problems of warmseason turfgrass turned yellow in winter, improve the cold resistance of the turfgrass
