| Abstract: | Reasons for the color change of E.pulcherrima were studied with physiological and biochemical paraments such as: chlorophyll,carotenoids,anthocyanin,Phenylalanine ammonia-lyase (PAL),pH of cell sap in leaves and soluble sugar content etc.The results showed that during the period of the leaf color transmittion of E.pulcherrima,the contents of plastid pigment,soluble sugar and pH of cells sap in leaves showed a high-low-high dynamic change,while the contents of anthocyanin and PAL activity showed the low-high... |
