摘要/Abstract

摘要： 为探究外源赤霉素溶液对长白山区辽东楤木种子萌发过程中生理活性物质变化的影响,采用质量浓度为0(对照组)、100、200、400 mg/L的赤霉素溶液浸泡长白山区辽东楤木种子,分析种子萌发过程中可溶性糖质量分数、可溶性蛋白质量分数、淀粉质量分数与淀粉酶活性的变化规律。结果表明:1)辽东楤木种子萌发过程中,其可溶性糖质量分数、淀粉质量分数与β-淀粉酶活性总体呈先升高后降低的趋势,ɑ-淀粉酶活性则总体表现为先降低后升高的趋势;2)与对照组相比,一定质量浓度的外源赤霉素溶液能够有效促进长白山区辽东楤木种子的萌发,并在层积处理20 d后提高种子内可溶性糖质量分数、可溶性蛋白质量分数与β-淀粉酶活性,降低淀粉质量分数,其中以质量浓度为400 mg/L的赤霉素溶液处理效果最明显;3)外源赤霉素溶液对种子萌发的促进作用主要是通过促进种子内淀粉的水解及可溶性糖的利用,同时诱导种子萌发过程中一系列重要蛋白质的合成而实现的。

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.
