摘要
测定黄连木叶片中花青苷、叶绿素a、叶绿素b、类胡萝卜素含量及年动态变化和秋季显色期可溶性糖及9种矿质元素的含量,探讨其叶色变化与可溶性糖和矿质元素的关系。结果表明:不同单株黄连木叶片中的叶绿素和类胡萝卜素的年变化趋势一致,而花青苷含量的年变化趋势分为平稳、增加、骤升3种类型。在9种矿质元素中,对花青苷含量影响较大的是氮、磷、钙、锰、锌,其中磷与花青苷含量呈显著性正相关,氮与其呈显著性负相关;可溶性糖与花青苷含量呈显著性正相关,而与叶绿素、类胡萝卜素呈显著负相关,氮与叶绿素、类胡萝卜素呈显著性正相关。
Content of anthocyanin,chlorophyll a,b,carotenoid,dynamic change of pigments,soluble sugars and nine mineral elements were measured in different color leaves of different trees of Pistacia chinensis. The relationship between the leaf color and all chemical components was discussed. The results indicated that the chlorophyll and carotenoid shared the same changing trend. There were three types of changes in anthocyanin content： smooth,increasing and surging. Among nine mineral elements,nitrogen,phosphorus,calcium,manganese,and zinc had the bigger influence on the anthocyanin content. Soluble sugars and phosphorus was prominently and positively correlated to total anthocyanin content;whereas nitrogen had negative correlation with total anthocyanin content. There was a negative relationship between soluble sugar and chlorophyll,carotenoid,and a positive relationship between nitrogen and chlorophyll,carotenoid.
