The Influence of Soil Texture on Maize Leaf Senescence During Later Growth Stage

The study on maize leaf senescence during later growth stage at different textural soils(sandy loam,light sandy,loam,clay) was conducted using pot cultivation in a field experiment.The main results are as follows:the maize leaves senescence increased in later growth stage,the activities of SOD and the leaf area decreased in different textural soils,while the content of MDA increased.Among the four textural soils,the leaf area and the activities of SOD in loam were the highest,the lowest in sandy loam.By contrast,the content of MDA in sandy loam was the highest,the lowest in loam.The different maize yield in the four textural soils reached significant level operated the same each other in field experiment.
