摘要:
高羊茅为冷季型草坪草,在夏季生长过程中,常遭受高温与干旱的双重胁迫。试验通过模拟干旱和高温环境条件,研究了高温与干旱双重胁迫对高羊茅生长及生理特征的影响。研究表明:随着双重胁迫时间的延长,对照组高羊茅无明显伤害症状,而处理组高羊茅的伤害症状逐步升级;叶片内过氧化物酶(POD)和超氧化物歧化酶(SOD)活性呈现出先增加后降低的趋势,与对照组相比,6 d始发生显著性差异;叶片可溶性糖含量、MDA含量、相对电导率逐渐增加,与对照组相比,6 d始发生显著性差异;叶片Pro含量逐渐增加,叶片含水量逐渐下降,与对照组相比,9 d始发生显著性差异。
Abstract:
Festuca arundinacea is a cold-season turf grass species which often suffers from joint stress of high temperature and drought in the summer. By simulation of drought and high temperature environment, the joint effects on its growth and physiological characteristics were studied. The results showed that as joint stress prolonged,(1)the injury symptoms aggravated gradually;(2)the activities of POD and SOD increased first and then reduced,with significant differences occurring between CK and treatment after 6 days’stress;(3)leaf soluble sugar content, MDA content, relative conductivity increased slowly,with significant differences occurring between CK and treatment after 6 days’ stress ;(4)gradually, leaf proline content increased while leaf water content reduced, with significant differences occurring between CK and treatment after 9 days’ stress. The research result will give a reference to the Festuca arundinacea turf grass maintenance in summer.
