| 摘 要： | 以大穗结缕草、沟叶结缕草、普通狗牙根和百慕大4种草坪草为材料,对其干旱胁迫过程中生理指标进行了研究,并采用隶属函数法对其抗旱性进行比较,以期为我国干旱和半干旱地区草坪草的栽培提供试验依据。结果表明：叶片相对含水量（RWC）在胁迫15d时比对照降低、而相对电导率（REC）、超氧化物歧化酶（SOD）和过氧化物酶（POD）活...

| Abstract: | In this paper,the Zoysia macrostachya Franch.et Sav.,Z.matrella(L.) Merr.,Cynodon dactylon(L.) Pers.and Bermudagrass are selected as materials to study the changes of physiological indexes under drought stress,and to compare the drought resistance with subjection function,in order to provide experimental basis for turfgrass cultivation in arid and semi-arid regions.The results show that on the 15th day during drought stress,the leaf relative water content(RWC) declines significantly,but leaf relative electr... |
