【摘要】 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、有效的方法更多还原

【Abstract】 Through determining the conductivity of lawn grass samples which have been treated with dry, heat and low temperature, and considering their behaviors under the condition of natural dry, heat and low temperature, this paper compares the differences of dry, heat and low temperature resistance among the genera, species and varieties of winter lawn grass and Summer lawn grass. The results show that there are obvious differences of resistance among the genera and species of winter lawn grass: Festuca>Poa>Laolium>Agrostis . Among the species of summer lawn grass, Axonopus compressus, Eremochloa ophiuroides, Cynodon dactylon, Zoysiatcnuifolia have quite good dry and heat resistance and Zoysia lenuifolia, Eragroslis nigra, Zoysia japonica, Sporebolus indicus, Eremochloa ophiuroides have fairly good cold resistance. The results of the test are in accord with the behaviors of field observations, thus confirming that determining conductivity is a simple, quick and effective way to test the resistance of lawn grass.更多还原
