通过测定经干热和低温处理的草坪草样本浸泡液的电导率，结合自然干热、低温条件下的表现，比较冷、暖季型草坪草属间、种间或品种间的耐干热、耐低温性能的差异．结果表明，冷季型草坪草耐干热性能，属间存在着显著差异：羊茅草属＞早熟禾属＞黑麦草属＞翦股颖属；同属的种间大部分也存在着显著差异．暖季型草种中，地毯草、假俭草、狗牙根、细叶结缕草等耐干热性能较为理想；细叶结缕草、黑画眉草、结缕草、鼠尾粟、假俭草等的抗寒性能较强．测试结果与田间观测表现一致，说明测定电导率是检测草坪草耐性的一种简便、快速、有效的方法 By measuring the conductivity of the soaking solution of turfgrass treated by dry heat and low temperature, combined with the performance of natural dry heat, low temperature conditions, compared with cold, warm-season turfgrass inter-genus or varieties of dry heat resistance Difference in low temperature performance. The results showed that cold-tolerant turfgrasses had a significant difference in their ability to resist dry-heat. There was significant difference between the two genus: Forsythia> Compositae> Lolium> Prunus. In the warm-season grasses, the resistance to dry heat, such as carpet grass, centipedegrass, bermudagrass and Zoysia matrella, were relatively satisfactory. Grass and other cold resistance stronger. The test results are consistent with field observations, indicating that the measurement of conductivity is a simple, rapid and efficient method of testing turfgrass tolerance
