Secondary Metabolites in Leaves of Purple-leaf Plum and Red-leaf Peach
-
摘要: 以红叶李和红叶桃叶片为试材,测定叶片不同时期叶绿素、花青素、类黄酮和可溶性糖含量变化以及POD和PAL活性。结果表明:红叶李和红叶桃叶片中叶绿素、花青素、类黄酮、可溶性糖含量以及花青素与叶绿素含量的比值均呈"下降-上升-下降"的变化趋势;红叶李和红叶桃叶片中花青素含量最高的时期分别在9月和4月;POD和PAL的活性变化均呈"下降-上升"的变化趋势。相关性分析表明,红叶李和红叶桃叶片中花青素含量与可溶性糖含量与POD和PAL活性呈显著正相关,而叶片中叶绿素和类黄酮含量的变化与POD和PAL活性无显著相关。Abstract: Contents of secondary metabolites, such as anthocyanins, chlorophyll, flavonoids, and soluble sugars, as well as the POD and PAL activities in the leaves of purple-leaf plum and red-leaf peach during growing stages were determined. The results showed that the changes in the contents of anthocyanins, chlorophyll, flavonoids, and total soluble sugars, as well as the anthocyanins/chlorophyll ratio, of both varieties were characterized by a decline-rise-decline pattern. The anthocyanin content peaked in September and April. Whereas, the activities of POD and PAL decreased initially and followed by an increase. The anthocyanin content and POD and PAL activities significantly correlated to the soluble sugar content in the leaves. However, no significant correlation between chlorophyll or flavonoids and the enzymatic activities was observed.
