Effects of Cyphomandra betacea Seedlings Intercropping with F1 Generations of Solanum photeinocarpum on Soil Enzyme Activity under Cadmium Stress

Abstract

Effects of Cyphomandra betacea seedlings intercropping with F1 generations of Solanum photeinocarpum on soil enzyme activity under cadmium (Cd) stress were studied. The activities of soil catalase, soil polyphenol oxidase, soil sucrase, and soil urease were measured. The results showed that under Cd stress, C. betacea seedlings intercropping with F1 generation of S. photeinocarpum increased soil polyphenol oxidase and decreased soil catalase activities. C. betacea seedlings intercropping S. photeinocarpum of mine ecotype and two F1 generations of S. photeinocarpum enhanced soil sucrase activity. C. betacea seedlings intercropping two ecotypes F1 generations of S. photeinocarpum enhanced soil urease activity.
