The effect of H2O2 on water convolulus(Ipomea aquatica)seed viability has been studied at length in this paper.The experiment results showed that H2O2 could stimulate seed germiination and improve seed viability, the relative germination rate and seedling rate increased by about 21.0%and 25.0%respectively when the concentrations, treatment hours and temperatures were 1% H2O2-30℃-8h(the best set).Seed viability was rather difference among different water convolulus varieties.With 1%H2O2 treatment,the effects on lower germination rate varieties and new harvested seed were more apparent.Compared with other seed vlability promoters,the effect of H2O2 was slightly better than the gibbereline(920)and markedly better than other The mechanism of H2O2 treatment improving seed viability was parimarily discussed also.
