| 摘 要： | 采用主成分分析法及隶属函数分析法对8 个芹菜品种幼苗的耐热性进行评价。结果表明：品种间差异显著的32 个耐热性指标在进行主成分分析后，得到7 个新的相互独立的综合指标；经隶属函数综合评价，供试芹菜品种幼苗耐热性从强到弱的顺序为：文图拉变异自交系＞加州王变异自交系＞津南实芹＞犹他52-70 ＞嫩脆西芹＞康乃尔＞伏芹＞金黄，与田间多年观察结果基本一致。

| Abstract: | The high temperature resistance of 8 celery（Apium graveolens L.） varieties at the seedling stage was evaluated by principal components analysis and subordinate function analysis．The results showed that 32 high temperature resistance indexes with significant differences could be classified by principal components analysis into 7 new comprehensive indexes with mutually independent components analysis．Through subordinate function analysis，the order of high temperature resistance from high to low was‘Wentula mutation lines’＞‘Jiazhouwang mutation lines’＞‘Jinnanshiqin’＞‘Yota 52-70’＞‘Cuinenxiqin’＞‘Kangnaier’＞‘Fuqin’＞‘Jinhuang’，which was consistent with the results of field observation in the past several years． |
