摘　　要：以12个番茄品种幼苗为试材,在低地温条件下,测定根系活力、渗透调节、自由基离子和酶活性等11个生理指标及3个形态指标,应用主成分分析法、隶属函数分析法和聚类分析法对生理和形态指标进行分析,以综合评价不同番茄品种的耐低地温能力。结果表明:不同番茄品种的14个生理、形态指标变化程度不同,表现出在低地温胁迫下,各生理指标之间存在着一定的协同和拮抗性。4个主因子代表14个生理指标的86.27%的数据信息,12个番茄品种的耐低地温能力强弱评价为:CM78>朝研>CM966>金粉秀美>胜美>中蔬4号>白果强丰>金冠1号>内番3号>旺粉>粉红番茄>金粉168。By the methods of principal component analysis,subordinate function,and cluster analysis,a comprehensive evaluation was conducted on the low ground temperature-resistance of 14 physiological indices of twelve marigold cultivars.The results indicated that the different tomato varieties of 14 physiological indicators in different degree, showing in the low ground temperature stress, the physiological indices exists between certain synergy and meet resistance. Six principal factors presented 86.27% of the information of the 14 indices. The comprehensive evaluation value of the low ground temperature-resistance of the 12 cuhivars was in the order of＇CM78＂〉Toward the research＂ 〉＇CM966＂〉 ＂Gold beautiful＂ 〉＇win beauty ＂ 〉＇Vegetarian in 4＂ 〉 ＂Prosperous powder＂ 〉＇Gold crown a number＂ 〉＇And within 3＂ 〉＇Gingko strong abundant＂ 〉＇Pink tomato＇〉＇gold 168＂.
