摘　　要：本研究以100份辣椒种质资源为材料,设置150 mmol/L NaCl胁迫处理,以蒸馏水为对照,分别统计种子发芽数,并对种子发芽率、发芽势、发芽指数等指标进行分析,同时采用模糊数学隶属函数法及耐盐分级对其进行耐盐性评价。结果表明,耐盐性排名前10位的辣椒种质资源为PC215、PC115-1、P24-7、PC88、PC330F3-1、PC210、PY353、PC311F3-1、PC200-2、PC349F3;PC308、PC236-2、PC66、PC289-2、PC220-1、PC28、PC267-1、PC323F3、PC237-3、PC135的耐盐性较弱,排在后10位;PC135的相对盐害率为100%,平均隶属函数值为零,耐盐性最差。Under the stress of 150 mmol/L NaCl,the germination rate,germination potential,and germination index of 100 capsicum germplasm resources were analyzed,and their salt tolerance was evaluated by fuzzy membership function method and grading of salt tolerance.The results showed that the top 10 salt-tolerant germplasms were PC215,PC115-1,P24-7,PC88,PC330F3-1,PC210,PY353,PC311F3-1,PC200-2 and PC349F3.The salt tolerance of PC308,PC236-2,PC66,PC289-2,PC220-1,PC28,PC267-1,PC323F3,PC237-3 and PC135 was weaker,and they were ranked as the last 10.Among them,the relative alkali damage rate of PC135 was 100%,and its average membership function value was 0,so its salt tolerance was the worst.
