| 摘 要： | 以茶花Camellia 3 个主要品种群的15 个品种为材料, 利用生理生化测定及SPSS 统计分析对其耐热性进行了研究。结果表明:持续7 d 36 ～ 38 ℃的高温胁迫能够有效区分不同茶花品种耐热性;生理生化测定结果的系统聚类与主成分分析能够对不同茶花品种的耐热性进行有效评价。云南山茶Camellia reticalata 及其杂种品种群耐热性较差, 茶梅C .sasanqua 耐热性较强, 而红山茶C .japonica 品种群耐热性变化范围较大。茶花品种耐热性与花型相关性不大。图1 表4 参15

| Abstract: | Heat tolerance of 15 Camellia cultivars was studied using physiological and biochemical mensuration as well as an SPSS statistical analysis .Results indicated that heat tolerance of different Camellia cultivars could be distinguished effectively under a heat stress between 36 -38 ℃ for one week and could be effectively evaluated using a main component analysis and cluster analysis from physiological and biochemical mensuration .Cultivars originating from C .reticulata and its hybrids had the worst heat tolerance , cultivars of C .sasanqua had better heat tolerance , and cultivars of C .japonica varied over a large range .Heat tolerance of Camellia cultivars had little correlation with flower types .
