四季竹对大气臭氧体积分数倍增的生理响应
Physiological responses of Oligostachyum lubricum with elevated atmospheric ozone concentrations
摘要
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 nL·L-1 of O3 concentration (TR-1), and 142-160 nL·L-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 0. Lubricum.关键词
