Abstract
Under the simulated salinity condition(pH=8.0,0.2% NaCl),poly-aspartic manganese(II),a Mn-SOD mimics(Mn-SOD) at some concentrations,were used to presoak Perilla frutescens seeds and to spray seedling leaves.On the seventh day,the width of the leaves,SOD and CAT activities,and MDA amount of Perilla frutescens were measured.Results showed that under salt-stressing condition,the sprouting percentage of the seeds presoaked by 0.1 mg/L poly-aspartic manganese(Ⅱ) was 5.33 times of unpresoaked ones.Presoaking activities helped to enlarge the width of the leaves,to raise SOD and CAT activities,and MDA amount.12.5 m g/L was the best spraying density.With the raising of poly-aspartic manganese(Ⅱ) amount,the MDA amount decreased.Under the experiment condition,poly-aspartic manganese(Ⅱ) mimics presoaking and leaf spraying could efficiently increase the sprouting percentage of Perilla frutescens and can raise their anti-salt-stressing ability during seedling period.
