Polyethylene glycol(PEG)-6000 was employed as osmotic agent for simulating water stress,to study the germination characteristics of rice grain in four difference concentrations osmotic solution and to establish the identification index for indirectly evaluating drought-resistance in germination period.The result showed that the inhibiting on seed germination in higher concentration of PEG was larger than that in lower concentration of PEG,and drought response index of germination rate was increased along with the decrease of PEG conentration and the course of germination.Germination rate after germinated 6 days in 20% concentration of PEG had more variance range and coeffecient of variation,better proportion on variety distributing than other's,it could reflect different response of rice variety on osmotic stress,so it was fit for drought-resistance identification on germination rate.Survival rate of seedling treated drought repeatedly was significantly correlated with the index of germination in osmotic stress and coleoptile length after germinated 8 days on 20% concentration of PEG,so index of germination and coleoptile length could be used as identification index for indirectly evaluating drougt-resistance at the seedling stage.
