| 摘 要： | 采用灰色关联分析(Gray correlation analysis), 探讨辣椒生理生化性状与耐高温高湿的关系.对分别处于高温高湿和正常条件下的10个辣椒品种(系)21个生理生化性状耐高温高湿系数进行了分析和评价.依据各品种(系)的加权关联度对参试品种(系)进行了聚类分析,参试品种(系)中极耐高温高湿的品种(系)有I、G二个品种(系).与耐高温高湿关联度最大的是花青素含量、过氧化氢含量、超氧化物歧化酶活性和脱氢抗坏血酸还原酶活性4个生理生化性状,它们在高温高湿双重逆境胁迫下所受的影响最大,与辣椒耐高温高湿性关系最密切.因而可以选用花青素含量、过氧化氢含量、超氧化物歧化酶活性、脱氢抗坏血酸还原酶活性等生理生化性状进行辣椒耐高温高湿的以性状为基础的选择,以提高选择效率. |

| Abstract: | This paper aims at probing the relationship between physic-biochemical traits and the high temperature and air humidity resistance of hot pepper varieties.A total 21 p hysic-biochemical traits that measured in 10 hot pepper varieties at high temperature and air humidity and control conditions,were analyzed using gray relational grade analysis method.Gray correlation degrees facilitated in identifying the high temperature and air humidity resistance of hot pepper.And the cluster based on the relation degree of 10 hot pepper varieties.Varieties that had the strongest high temperature and air humidity resistance among the 10 hot pepper varieties were I and G.It was concluded that the physic-biochemical traits had the closest relationship with the high temperature and air humidity resistance of hot pepper,and these traits were significantly influenced by high temperature and air humidity stress,thus had the greatest relation degree with the high temperature and air humidity index.So the physic-biochemical traits including leaf flower pigment content,H2O2 content,SOD,DHAR could be used |
