Abstract: The physiological indexes of Camellia fluviatilis under waterlogging stress were studied. The results showed that with the extension of flooding time, the chlorophyll contents of both waterlogging treatments were lower than those of control group. Under waterlogging stress, SOD activity, soluble protein and MDA contents of the waterlogging treatments tended to rise first, then fall and rise again as the flooding time extending. The content of soluble sugar was falling first and then rising. All physiological indexes indicated C. fluviatilis was adapted to waterlogging stress in a certain degree.

Key words: waterlogging stress, Camellia fluviatilis, physiological index

摘要: 以窄叶短柱茶Camellia fluviatilis为材料,开展其盆栽苗水淹胁迫研究。结果表明,随着水淹时间延长,水淹胁迫组在淹水全过程中叶绿素含量均低于同期对照组;水淹胁迫下超氧化物歧化酶(SOD)活性、可溶性蛋白质含量、丙二醛(MDA)含量均随淹水时间延长呈先升后降再上升的趋势,可溶性糖含量则呈先降再升趋势。总体表明窄叶短柱茶对水淹胁迫有一定的适应反应。
