Abstract: Under drought condition, the rate of permeability and water content of leaves of peanut, (Arachia hypogaea L.)seedlings can be reduced by CCG at concentrations of 75, 150 and 300' ppm. It is found that the 150 ppm CCC treatment increases the peroxidase activity and decreases the malondialdehyde (NDA) content and superoxide dismutase (SOD) activity. CCC treatment has accumulated the endogenous ABA content in the leaves of peanut seedlings grown in normal or drought condition, and the 150 ppm CCC treatment has shown better effect. The increasing drought stress of peanut seedlings after CCC treatment perhaps results from higher level of endogenous ABA, which leads to series of metabolic responses in peanut seedlings, and eventually increases the ability of drought resistance.

Key words: CCC, ABA, Drought resistance, Peanut
