Abstract

To investigate the effects of exogenous gibberellin(GA3)solution on the variations of physiological activity substances during the germination process of Aralia elata seeds in the Changbai Mountain region,seeds of this region were soaked in GA3 solutions at mass concentrations of 0(the control group),100,200,400 mg/L,and the variations of the mass fractions of soluble sugars,the mass fractions of soluble protein,the mass fractions of starch,as well as the amylase activities were analyzed during the seed germination process.The results indicated that during the germination process of Aralia elata seeds,the mass fractions of soluble sugars and starch,as well as the β-amylase activities overall exhibited a trend of initially increasing and then decreasing,while the α-amylase activities generally showed an opposite trend,initially decreasing and then increasing.Compared with the control group,appropriate mass concentrations of exogenous GA3 solution could effectively facilitate seed germination of Aralia elata seeds in the Changbai Mountain region,and increased the mass fractions of soluble sugars,the mass fractions of soluble protein,and the β-amylase activities,while reduced the mass fractions of starch in the seeds after 20 days of stratification treatment.Notably,the treatment with the mass concentration of 400 mg/L GA3 solution demonstrated the most significant effect.The promotion of exogenous GA3 solution on seed germination was primarily achieved by promoting the hydrolysis of starch and enhancing the utilization of soluble sugars within the seeds,as well as currently inducing the synthesis of a series of crucial proteins during the seed germination process.

Key words： GA3; the Changbai Mountain region; Aralia elata; seed germination; physiological activity substances
