干旱及复水处理下坪用黑麦草和高羊茅抗旱特性比较
Responses of tall fescue and perennial ryegrass turfgrasses to drought stress and re-watering treatment
摘要
Abstract
Turfgrasses always go through the process of ＂drought-re-watering-drought-re-watering…＂ in the growth seasons.It is a good opportunity to examine the growth and morphology responses of turfgrass to drought stress and re-watering treatments.In this study,the responses of Barlexas cultivar of Tall Fescue（Festuca arundinacea） and Premier cultivar of Perennial Ryegrass（Lolium perenne） to drought stress and re-watering treatments were investigated.The results showed that drought stress caused a significant decline in TQ,leaf RWC,LWP,GR,ET,SWC and a significant increase in EL,LW of both cultivars.After re-watering,all the indicators rehabilitated to some degree.Leaf RWC,LW,LWP of both cultivars and TQ of Barlexas reached the same order of control group,however,EL,ET of both cultivars and TQ of Premier do not reached the order of control group.Through the entire experiment,Barlexas showed better performance than Premier,which suggests that Barlexas has a stronger drought resistance and recovery capability than Premier.关键词
