Abstract

Effect of root exudates from the cotton material (CCRI 35) collected by water on cotton seedling growth and physiological activity was investigated. The results showed that root length, plant height, above-ground fresh weight,under-ground fresh weight of cotton seedling and cotton seed germination were promoted by root exudates at the low concentration, while restrained at high concentration.Root vigor,chlorophyll contents were reduced by root exudates at different concentrations. SOD activity was promoted by root exudates at the low concentration.

Key words
