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.

摘  要:
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:guardian Z1 and inferno>K.B.G and classis>Fawn.
