Abstract:

The change of chlorophyll, carotenoid, anthocyanin and soluble sugar content was investigated during the leaf color transition of Cercis cannadensis ‘Forest pansy’ in Shandong province. The results indicated that the anthocyanin content decreased and presented “M” tendency with the days increased..The chlorophyll and carotenoid content elevated gradually. The soluble sugar content presented disordered multi-peak curve. The cholorphyll(r=-0.681**) and carotenoid(r=-0.757**) had remarkablely negative correlation with the anthocyanin. The soluble sugar was not correlated to the anthocyanin. The chlorophyll and the anthocyanin showed the logarithmic curve correlation, while the carotenoid and the anthocyanin displayed the exponential curve correlation.
