Objective:
To investigate the dynamic changes of main physiological indexes, active constituent of Chrysanthemum morifolium and their correlation during the whole growing period and provided a reference basis for the field production.
Method:
Take Ch. morifolium cv. Xiaobaiju, Ch. morifolium cv. Hongxinju and Ch. morifolium cv. Changbanju were taken as the research objects, the main physiological and biochemical indexes were determined, the correlation among them was analyzed.
Result:
The trend of each main physiological index and active component were different during the whole growing period. Agronomic characters, physiological and biochemical indexes and economic characters had correlation in different degree.
Conclusion:
Varieties with higher plant height, more branch and cephaloid numbers may be used for breeding for high yield, and varieties with higher chlorophyll content and POD activity, lower GSH content and SOD activity may be used for breeding for high content of the active components.
