Response of Lolium perenne Growth to Cadmium Stress

Abstract

The chlorophyll, malondialdehyde and relative conductivity of Lolium perenne had different degrees of physiological response to Cd stress. Lolium perenne had certain physiological adaptability to Cd stress, which could reduce the damage of Cd to Lolium perenne cells. Low concentration of Cd stress could also promote the synthesis of chlorophyll and increase the photosynthetic products. Once the concentration of Cd was too high, the growth of Lolium perenne would be affected. The accumulation of Cd in plants exceeds a certain limit, which damages the physiological function of plants and affects the normal growth of plants. It is suggested that Lolium perenne has a certain remediation ability to cadmium contaminated soil. The experiment can provide a certain reference for the screening of cadmium tolerant plants and the remediation of cadmium contaminated soil.
