摘要
在照光和黑暗条件下研究了不同浓度的６－ＢＡ和ＧＡ＋６－ＢＡ混合剂处理对油茶离体叶片衰老的影响．结果表明，在光条件下６－ＢＡ可以保持叶片细胞的超氧歧化酶（ＳＯＤ）活性（为对照的１２９％），降低了膜脂过氧化产物丙二醛（ＭＤＡ）的积累（为对照的４７％），延缓叶绿素和蛋白质的降解．说明６－ＢＡ有延缓叶片衰老的作用，在黑暗条件下上述生理指标的水平较低，表明光对６－ＢＡ的作用有一定的增益效应．
Experiments were carried out to study the effect of different concentration 6-BA solutions and 6-BA-GA mixtures on detached-leaves senescence of Camellia oleifera under illumination and dark,the results indicated that:under illumination,6-BA could maitain the activity of SOD,reduce the accumulation of chlorophyll and protein,therefore,6-BA played delayed action on leaves senescence of Camellia oleifera,The delayed acton of 6-BA on leaves senescence under dark tallied with that under illumination,but the degrees were lower.The 6-BA-GA mixture hardly had evident effect on senescence.
