| 摘 要： | 为了探究不同表现型无性系叶片呈色机理，以3个不同叶变色类型的（绿、红、黄）元宝枫(Acer truncatum Bunge)的无性系（G-绿、R-红、Y-黄）植株为试验材料，于2011年10月19日—11月11日叶片转色期间分别测定总叶绿素、类胡萝卜素、可溶性糖和花色素苷含量的变化。结果表明：各无性系的叶片在转色前存在较低含量花色素苷，叶片转红是大量合成花色素苷的结果，元宝枫无性系叶片颜色与花色素苷和各色素比例有关，叶片呈色不同主要由基因型决定。不同无性系的可溶性糖含量存在显著差异，无性系R的可溶性糖含量最高，花色素苷的合成可能受高可溶性糖含量的诱导。

The Dynamic Changes of Main Component in Leaves of Acer truncatum Bunge Clones in Autumn |

| Abstract: | In order to reveal the color emerging mechanism of maple leaves in Autumn, 3 kinds of Acer truncatum Bunge clones were taken as material. The variations of chlorophyII, carotenoids, anthocyanin and soluble sugar content in maple leaves were measured during the color-changing period from 19-October to 11-November, 2011. The results indicated that: little anthocyanin was contented in the leaves of 3 kinds of maple clones before the color change, which had nothing to do with the following color-changing. The reason for leaves of clone R turn red was not only because of induction of chorophyII and carotenoids, but also the following large production of anthocyanin. The color changing of leaves in different clones of maple trees was apllied to anthocyanin content and pigment proportion and decided by genotype. There was significant difference in the content of soluble sugar in different clones in which clone R was the highest one. The process of anthocyanin production might be induced by the high content of soluble sugar. The carotenoids proportion was highest in clone Y and was lowest in clone R. |
