Rising And Falling Rule Of Anthocyanins Content Leaf Coloring Of Acer Truncatum Bungeand And The Related Research Of Physiological Mechanism

To explore the change of anthocyanin content leaf coloring of Acer truncatum Bunge and its related physiological mechanism in the synthetic process, the Acer truncatum bunge leaf coloring is divided into11stages, through the determination of anthocyanin,pheophytin, soluble sugar, soluble protein,PAL activity,PPO activity in the stages of leaf, to discuss the influence of above factors to accumulation content.The results showed that the leaves turn color in the process,Anthocyanin contents has sharp rise on September27th and to reach maximum at the end of October; Soluble sugar content had risen rapidly since September16th,and in this color turning stage,soluble sugar showing a rising trend, it was significantly positively related to the0.01level. At the early stage of coloring,PAL,PPO showing high activity.Its started to rise time is earlier than the anthocyanin content rise time, they has significantly negative correlation with anthocyanin content.Changes in soluble protein content and anthocyanin content completely opposite,and it from the beginning of September16th degradation. Soluble protein degradation time than the anthocyanin content rise in two weeks earlier,it was significantly negative correlation at the0.01level.In this stage,pheophytin content declined in September23th,the time degradation of pheophytin earlier than the pigment glycosides rise4-5days,more than a week late soluble protein content degradation. Anthocyanin contents and pheophytin content were significantly negative correlation at the0.01level.
