摘　　要：研究比较了2种冷季型草坪草高羊茅和草地早熟禾中5个品种的耐热性。结果表明:高羊茅品种Fawn的耐热性在所有供试品种中表现最差。高羊茅品种守护神Z1和强劲在热胁迫处理的过程中表现稳定,其耐热性显著的优于2个草地早熟禾品种K.B.G和经典。而守护神Z1和强劲之间、K.B.G和经典之间的耐热性差异并不显著。供试的5个草坪草品种的耐热性排序结果为:守护神Z1和强劲>K.B.G和经典>Fawn.This paper was conducted to screening varieties of five cool-season grasses for heat-resistance. The result showed： the tall fescue grass Fawn was the worst performer in all of the heat-resistant grasses. After high-temperature heat stress, the difference between guardian Z1 and inferno, K. B. G and classis was not significant. But guardian Z1 and inferno was higher than K. B. G and classis in heat tolerance. The sequence of heat tolerance of five grasses was： guardi- an Z1 and inferno〉K. B. G and classis〉Fawn.
