摘要: 【目的】探究不同营养液浓度对蒙古黄芪幼苗生长及其药用成分的影响,为蒙古黄芪进行营养液育苗提供参考。【方法】以蒙古黄芪为试验材料,采用园土(CK)、标准浓度Hoagland和Aron通用营养液(Y1)、1/2标准浓度Hoagland和Aron通用营养液(Y2)、1/3标准浓度Hoagland和Aron通用营养液(Y3)4个处理进行无土培养,分析蒙古黄芪生长形态指标、生理指标和药用成分含量。【结果】与其他处理相比,Y1处理可提高蒙古黄芪幼苗的株高、主根长、分枝数、茎粗、芦头茎粗、主根粗。与CK相比,Y1处理可显著(P<0.05)提高蒙古黄芪幼苗叶片叶绿素含量、根系活力,显著(P<0.05)降低根系游离氨基酸含量,显著(P<0.05)增加出苗后70~77 d蒙古黄芪幼苗根系中黄芪总黄酮含量和出苗后49~77 d黄芪总多糖含量。【结论】采用标准浓度Hoagland和Aron通用营养液育苗,可以促进蒙古黄芪幼苗生长和药用成分黄芪总黄酮、黄芪总多糖的积累。

Abstract: 【Objective】 To investigate the effects of different nutrient solution concentration on Astragalus mongholicus Bunge seedling growth and its medicinal components in order to provide reference for nutrient solution seedling raising of Astragalus mongholicus Bunge.【Methods】 Astragalus mongholicus Bunge were grown on four nutrient solutions,garden soil(CK),standard concentration Hoagland and Aron general nutrient solution(Y1),half of the standard concentration Hoagland and Aron general nutrient solution(Y2),and 1/3 of standard concentration Hoagland and Aron general nutrient solution(Y3). The growth morphological indicators,physiological indexes,and medicinal components of the plants were analyzed.【Results】Y1 treatment improved the plant height,main root length,branch number,stem diameter,basal part of stem diameter,and main root diameter of Astragalus mongholicus Bunge seedlings when compared to other treatments. Compare with the CK,Y1 treatment significantly(P<0.05)increased the chlorophyll content and root activity in Astragalus mongholicus Bunge seedlings, significantly (P<0.05) decreased the content of free amino acids in roots,and significantly (P<0.05) increased the content of total flavonoids in seedling roots 70 to 77 days after emergence,as well as the total polysaccharides in seedling roots 49 to 77 days after emergence.【Conclusion】Raising Astragalus mongholicus Bunge seedlings in Hoagland and Aron general nutrient solution at a standard concentration boosted seedling growth as well as total flavonoids and polysaccharide accumulation.

Key words: Nutrient solution, Astragalus mongholicus Bunge, Seedling, Growth, Total flavonoids, Total polysaccharides
