Effects of Soil pH Value on Growth and Physiological Characters of Lupinus polyphylla Lindl

Infection of different pH of soil on growth and physiological characters of Lupinus polyphylla was studied.Results indicated that with the decline of pH,the rate of yellow plant decreased while chlorophyll rose in content,the activities of peroxidase(POD) increased and SOD activities increased also.The chlorophyll content a/b and activity of catalase were no significant difference with soil pH change.
