Abstract
Cotton varieties with different temperature sensitivities were used to explore the effect of the exogenous nitric oxide donor sodium nitroprusside(SNP) on chilling tolerance and germinability of cotton seed during the imbibition period.The results showed that,under low temperature stress,nitric oxide treatment increased activities of peroxidase(POD),catalase(CAT),superoxide dismutase(SOD),ascorbate peroxidase(APX),and soluble protein and proline(Pro) contents,and decreased the relative conductivity and malondialdehyde(MDA) content in the embryo of cotton seed.The nitric oxide treatment also significantly increased the average germination rate and shortened the germination time.After 48 h of seed imbibition at low temperature,the germination rate was increased by 29.85% and the germination time was decreased by 3 d in the SNP treatment compared with the control.These results indicate that nitric oxide treatment can improve the chilling tolerance during the seed imbibition period and enhance seed germination ability.
