摘　　要：以鸡爪槭、金陵黄枫和荷兰黄枫为材料,从10月下旬至12月上旬叶片秋冬转色期测定叶绿素、类胡萝卜素、花色素苷和可溶性糖含量,比较不同试材各指标的变化趋势。结果表明,试验期间3份试材叶片叶绿素含量均呈现下降趋势;叶绿素a与叶绿素b比值均呈先上升后下降的趋势;类胡萝卜素含量呈先上升后下降,最后趋于稳定的趋势;花色素苷及可溶性糖含量均呈上升趋势。叶绿素与类胡萝卜素、叶绿素与花色素苷、类胡萝卜素与花色素苷之间的比值呈下降趋势。花色素苷含量与总叶绿素含量呈负相关,与可溶性糖含量呈正相关。In order to reveal the physiological characteristics in the changes of maple leaf color,the contents of chlorophyll,carotenoid,anthocyanin and soluble sugar in three maple plants leaves were measured during the color-changing period from late October to December.The results showed that the chlorophyll content decreased gradually in three maple leaves.The chlorophyll a/b rose initially,and then went down.The carotenoid content rose initially,then went down,and then assumed the tendency of stability.The anthocyanin and soluble sugar content rose during the experiments.The ratio of chlorophyll and carotenoid,chlorophyll and anthocyanin,carotenoid and anthocyanin presented the downward trend.The anthocyanin had negative correlations with contents of chlorophyll,and significant positive correlations with soluble sugar.
