摘要:
采用盆栽育苗法，在5种冷季型草坪草苗期连续干旱胁迫下测定植株高度，根系生长，叶片相对含水量和质膜透性等抗旱指标，以综合评价5种冷季型草坪草的抗旱性能。研究结果表明：供试材料在连续干旱胁迫下，叶片相对含水量呈下降趋势，质膜透性有所增加。综合分析可知，5种冷季型草坪草的苗期抗旱性能由强多弱依次为：多年生黑麦草>高羊茅>无芒雀麦>紫羊茅>匍匐翦股颖。
Abstract:
Through cultivating five cold-season turfgrass (Lolium perenne, Agrostis stolonifera, Festuca rubra, Festuca arundinacea, Bromus inermis) in basin, their drought to lerance indexes, including the planting height, the root growth, the relative water content of leaves, the penetration of membrane, were comprehensively evaluated to compare their drought tolerance.The results showed, under the stress of continuous drought, the relative water content of leaves had a descending trend, while the penetration of membranes lightly increased.And their sequence of drought tolerance during seedling was Lolium perenne>Festuca arundinacea>Bromus inermis>Festuca rubra>Agrostis stolonifera.
