摘要: 利用灰色关联度分析法,对干旱胁迫下5个茶树品种的部分抗旱相关的生理性状与其抗旱指数的关联度进行分析和评价。结果发现,5个生理性状与抗旱指数的关联程度大小依次为:超氧化物歧化酶活性(0.6658)、丙二醛含量(0.6595)、可溶性糖含量(0.6282)、过氧化物酶活性(0.6094)、游离脯氨酸含量(0.5950)。并通过对5个茶树品种与抗旱指数的关联分析,得出5个参试材料抗旱性强弱依次为:D-1、特早213、S-1、福鼎大白茶、T-1。

Abstract: A total of 5 physiological traits measured in 5 tea cultivars which grown at drought conditions, and analyzed using gray relational grade analysis method. Results showed that, the analysis between each trait and its drought tolerance index were ranked according to their gray correlation degree to drought tolerance as follows: activities of SOD(0.6658), malondialdehyde content(0.6595), soluble sugar content(0.6282), activities of POD(0.6094), dissociative proline content(0.5950). The drought tolerance of tested cultivars was decreased as follows: D-1, Tezao213, S-1, Fu-ding-da-bai, T-1.

Key words: tea plant, drought tolerance, physiological traits, gray correlation analysis
