摘要: 草坪草作为重要的园林绿化材料，在北方冬季会受到冷害和冻害的威胁。植物生长调节剂常被用于提高植物的抗寒抗冻能力。为探讨植物生长调节剂对常见冷季型草坪草抗冻能力的作用及其生理机制，本研究在分析了低温胁迫对草坪草生理指标的影响的基础上，综合评价了多效唑、脱落酸、水杨酸、抗倒酯等植物生长调节剂对冷季型草坪草抗冻能力的影响，并指出植物生长调节剂对冷季型草坪草抗冻能力具有重要的调节作用，为植物生长调节剂在冷季型草坪草养护中的合理应用提供参考。
Abstract: Lawn grass, as an important landscaping material, is stressed by cold and freezing in the northern winter. Plant growth regulators were often used to improve the cold resistance of plants. To discuss the effect of plant growth regulator on the freezing resistance of cold season turfgrass and its physiological mechanism, the influence of low temperature stress on physiological indexes of turfgrass was firstly analyzed in this study. And then the effects of paclobutrazol, abscisic acid, salicylic acid, trinexapac-ethyl and other kinds of plant growth regulator on cold season lawn grass were summarized. The important regulation effect of plant growth regulator on the frost resistance of cold season turfgrass was discussed at last. All above studies aimed at providing an important suggestion on the reasonable application of plant growth regulator in lawn grass maintenance.
