摘　　要：为探明无花果品种抗寒能力,以15个无花果品种为试材,分析低温下(1,-6,-13,-20,-27℃)无花果枝条中相对电导率、可溶性糖、可溶性蛋白、丙二醛(MDA)以及脯氨酸(Pro)等指标含量变化,计算低温半致死温度(LT_(50)),利用模糊隶属函数法综合评价其抗寒性。结果表明,随着处理温度的降低部分无花果品种枝条中相对电导率表现为先下降再升高趋势,低温半致死温度在-10.034—-17.538℃之间,达到显著差异水平;MDA,Pro,可溶性蛋白和可溶性糖含量均呈升高或先升高后降低的趋势。模糊隶属函数法对抗寒性综合评价结果表明,抗寒性表现最好的为波姬红,其次为布兰瑞克,尼禄抗寒性最弱。In order to find out the cold-resistant quality of fig varieties,15 varieties were used as test materials to analyze the relative electrical conductivity,soluble sugar,soluble protein,malondialdehyde(MDA)and proline(Pro)under low temperature(1,-6,-13,-20,-27℃)stress.The fuzzy membership function method was used to evaluate their cold resistance.The relative electrical conductivity of branches showed an increasing trend at first and then decreasing trend as the treatment temperature dropped.The half lethal temperature of 15 varieties ranged from-10.034℃to-17.538℃,with obvious difference.But their contents of MDA,proline,soluble sugar,and soluble protein increased or increased at first and then decreased with the treatment temperature dropped.The results of fuzzy subordinate function value analysis showed that‘Bordeaux’with a high value of subordinate function appeared strong cold resistance,followed by‘Brunswick’.However,‘Nero’showed cold-sensitive.
