Waterlogging Tolerance of ground-cover chrysanthemum
Abstract：This paper studies the waterlogging treatment effects on the growth of ground-cover chrysanthemum. Experiment by observing ground-cover chrysanthemum roots, stems, leaf morphology changes and measuring physiological indices, including superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) activity and membrane lipid oxidation product malondialdehyde (MDA) content, chlorophyll content, soluble protein content, screening out the most suitable varieties of ground-cover chrysanthemum, and suitable for the soil and the weather condition in Shanghai area, which has the excellent resistance varieties. The results showed out: flooding tolerance identification time is suitable for 12 days. Under waterlogging, ground-cover chrysanthemum root vigor decreased sharply, but Yuhuajinhua during the early stress period showed higher root vigor; on the whole， the chlorophyll content showed the trend of first increasing and then decreasing; According to the observation of morphology, Yuhuajinhua and Yuhuajingui have a better flooding tolerance while Yuhualuoying and Yuhuajinxing have a lower one.
