Abstract
Rice seeds were immersed in CaCl2 soIution or water (as control ) for 18 hours, and then germinated. The seedlings treated with Ca2+ showed higher relative water content and lower relative plasmalema permeability under osmotic stress by -o. 5 MPa, which indicated that drought resistance was increased by Ca2+ treatment. Soaking seeds with chloropromazine (CPZ, 2 mmol/L) and CPZ (2 mmol/L) + Ca2+ (2o mmol/L) also increased the drought resistance of rice seedlings. After treatment with osmotic stress for one day, superoxide dismutase (SoD) and catalase (CAT) were activated, and the contents of ascorbate (AsA) and reduced glutathione (GSH) were increased by soaking seeds with 2o mmol/L of Ca2+, These results indicated that Ca2+ treatment increased protection against membrane lipid peroxidation and stability of membranes and therefore resulted in the increase of drought resistance of rice seedlings.
