Introduction on progress of turfgrass draught resistance

Studies on mechanism and evaluation of turfgrass drought resistance were comprehensively reviewed in this paper based on associated technical literatures at domesticand aboard. The mechanism of turfgrass drought resistance involved drought avoidance and drought tolerance. The traitsof deep, broad and vigour root and reducing loss in transpiration wereconsidered as the important essentials of drought avoidance.Decreasing osmotic potentials through osmoregulation and maintaining turgor press at certain level as essentials ofdrought tolerance. Plasm membrane stability, turf quality, water content in leaves and proline accumulation under the drought stress were important indicesfor assessing drought resistance in turfgrass. Major turfgrasses were ranked by the drought resistance and attentionsin the drought resistance study were put forward.
