| 摘 要： | 为了研究不同光质处理对蒙古黄芪(Astragalus membranaceus)品质及产量的影响,以一年生幼苗为材料,用不同光膜(红色光膜、黄色光膜、蓝色光膜、白色光膜及自然光照)进行不同光质处理,测定其根生物量、3种主要有效成分含量及单株产量。结果表明,蓝光处理后黄芪根系生物量是对照(3.37 g·株-1)的1.25倍,红光处理的黄芪根系生物量仅为1.19 g·株-1,显著低于自然光处理,说明蓝光促进了根系生物量的积累,红光不利于根系生物量的积累;蓝光处理显著提高了黄芪根中多糖、黄酮和甲苷的含量(P <0.05);多糖、黄酮、甲苷产量分别为27.95 mg·株-1,5.30 mg·株-1和0.87 mg·株-1,说明用蓝光处理有利于提高黄芪的品质和产量,红光处理抑制了有效成分的积累。 |

| Abstract: | Astragalus mongholicus seedlings was cultured under different light quality membranes(red, yellow, blue, white and nature light)to measure the index of growth and active ingredient and study the effects of different light quality on root growth and the accumulation of active ingredient in A. mongholicus seedlings. The results showed that the effects of different light quality on growth and the accumulation of active ingredient in A. mongholicus were obviously different. The dry-matter of A. mongholicus seedlings under the blue light was 1.25 times that of natural light treatment, while the root dry-matter of A. mongholicus in the treatment of red light quality membrane only had 1.19 g per plant and was significantly lower than the natural light treatment (3.37 g per plant) showing that blue light membrane promoted the accumulation of root dry-matter than the red light membrane. The contents of ploysaccharides, flavone and astragaloside significantly increased under the blue light quality treatment (P <0.05). The influences of different light quality on the root yield of A. mongholicus had different. The ploysaccharides, flavone and astragaloside contents of A. mongholicus (27.95 mg per plant, 5.30 mg per plant, and 0.87 mg per plant) were the highest in the blue light membrane treatment. Consequently, blue light membrane treatment can improve the yield and quality of A. mongholicus, while red light membrane treatment can cause the inhibition of the accumulation of active ingredient. |
