Abstract

The purpose of this paper is to reveal the physiological response mechanism of rhizome roots of Phyllostachys rivalis to long-term water stress. The physiological response of primary and secondary rhizome roots of 1-year-old Ph. rivalis to long-term flooded conditions was studied in a pot experiment with treatments of artificial irrigation water supply (CK) and flooding six months (TR). The root activity, antioxidant enzyme activity, membrane lipid peroxidation and osmotic adjustment substance contents in bamboo rhizome roots were investigated. The results are as follows. In general, the root activity, antioxidant enzyme activity, MDA content, relative electron conduction and soluble protein content of primary roots were significantly higher than that of the secondary roots. Under long-term flooded conditions, the root activity, antioxidant enzyme activity of primary and secondary roots were significantly lower than that of the CK. The relative electron conductivity and MDA content increased significantly. The root activity and CAT activity of bamboo rhizome roots growing in water were significantly higher than those growing in soil, on the contrary were SOD and POD activity. And Ph. rivalis can adapt to stress of long-term flooded conditions by maintaining the overall higher levels of root activity, antioxidant enzyme activity, soluble protein content, especially primary roots and bamboo rhizome roots growing in water. The results indicated that the rhizome roots of Ph. rivalis could adapt to long-term flooded conditions and survived through the balance adjustment of antioxidant system. Response of primary roots to waterlogging was much stronger than the secondary roots, and the bamboo rhizome root growing in water played an important role in adapting the flooded conditions.
