摘　　要：Uncovering the mechanism of hydrogen sulfide(H2S)in improving rice seed germination under aluminum(Al)toxicity conditions is important for rice production in acidic soil.In the present study,an Al sensitive rice variety Kasalath was used.Pretreatment with 0.1 mmol/L sodium hydrosulfide(NaHS,H2S donor)under 70 mmol/L AlCl3(indicated as Al+NaHS treatment)increased rice seed germination by 27.95%,germination potential by 474.16%,and the germination index by 43.44%,compared with Al treatment.The treatment of Al+NaHS reduced the Al content in rice seeds by 16.31%and 32.11%and increased the internal H2S content by 3.82%and 8.90%at 3 and 5 d of treatment,respectively,compared with Al treatment.Al+NaHS treatment significantly increased the activities of superoxide dismutase(SOD)。
