摘要： 以4种不同的狗牙根品种为研究对象,在人工控水条件下,对已成坪的草坪进行自然干旱胁迫处理,结果表明:供试品种在干旱胁迫下,植株绿叶率、叶片相对含水量均呈下降趋势,丙二醛与游离脯氨酸的含量则有所增加,但品种间存在显著差异。综合分析结果,4种狗牙根品种抗旱性强弱为:C3,C1>A3>A5。

Abstract: Under man-made water stress, study on drought tolerance of four bermudagrass varieties was carried out in the established turf. The results showed that: under the stress of continuous drought, the relative water content of leaves and the rate of the green parts of leaves had a descending trend, while the content of the free proline and the malondialdehye increased. The sequence of drought tolerance of the four Bermudagrass varieties was: C3, C1> A3> A5.

Key words: Bermudagrass, Drough-t resistance, Turf
