Abstract:
One-year-old seedling of chestnut ‘Huangpeng’was used as test material，a hydroponic experiment was carried out to study the effects of exogenous hydrogen sulfide at the concentration of 0.5 mmol?L-1 and 1.0 mmol?L-1 on the chlorophyll content under 15%PEG stress，malondialdehyde(MDA)，proline(Pro) and the activities of antioxidant enzymes of chesnut seedlings were studied，to investigate the related mechanisms of exogenous hydrogen sulfide regulation of drought stress of chesnut.The results showed that under drought stress spraying exogenous hydrogen sulfide obviously reduced the content of MDA，and significantly increased the contents of chlorophyll and proline，and the activities of SOD，POD，CAT.The previous evidence showed that exogenous hydrogen sulfide was favorable to decrease the damage degree of cell membrane under drought stress，which enhance the ability of resisting drought stress in chenut leaves.0.5 mmol?L-1 NaHS concentration was better.
