Abstract

This research was conducted to provide theoretical evidence for bamboo cultivation during this time of possible climate change. Open-top chambers （OTCs） were employed to determine the effects of elevated ozone on photosynthetic pigment content，soluble protein content，soluble sugar content，lipid peroxidation，and anti-oxidation enzymes in the leaves of Oligostachyum lubricum using a split-plot design with treatments of Control （NF），92-106 nLL-1 of O3 concentration （TR-1），and 142-160 nLL-1 of O3 concentration （TR-2），three replications. Results showed that，after 90 d，compared with NF，in treatments TR-1 and TR-2 there were significant decreases in the contents of chlorophyll （P = 0.002 4），carotenoids （P = 0.049 4），and soluble protein （P = 0.031 5），as well as superoxide dismutase （SOD） activity （P = 0.033 0） with significant increases in relative electrical conductivity （P = 0.013 5），peroxidase （POD） activity （P = 0.039 6），and malondialdehyde （MDA） content （P = 0.000 4）. Soluble sugar content decreased significantly （P = 0.003 7） only in treatment TR-2. Also，in leaves of TR-2 compared to TR-1，there was a significant increase in electrical conductivity （P = 0.044 8） and MDA content （P = 0.000 2），but a significant decrease in soluble sugar content （P = 0.001 5）. Thus，elevated ozone concentrations intensified the damage to membrane lipids and destroyed the structure of cell membranes，thereby affecting normal growth of O. lubricum. ［Ch，2 fig. 1 tab. 22 ref.］
