草坪草干旱胁迫研究进展

Research progress in effect of drought stress on turfgrass

干旱胁迫是影响草坪草生长最主要的环境胁迫因子之一。对草坪草的抗旱性研究方法、抗旱性鉴定、抗旱机制及提高草坪草抗旱性的主要途径做了概述,并探讨了目前我国草坪草抗旱研究存在的问题、研究重点和发展方向。

Drought stress is one of the chief environmental stress factors to turfgrass growth. In recent years, the research on turfgrass drought stress has gradually become a hot spot, and the great progress has been achieved. Many researches in China were concentrated in mechanism of drought resistance. However, it＇s still in the initial stage in comparing with other crop science in China and turfgrass industry abroad. The research methods, drought resistance identification, mechanism of drought resistance and its improvement methods were summarized in this paper. The current status of research on turfgrass drought stress in China such as existing problems, research key point and development trend were also discussed.
