摘要:

明确黄芪种间差异对其产业化种植有着重要影响。在田间试验条件下,对蒙古黄芪与膜荚黄芪的根系结构发育、根形态、药用成分及表观生长量等指标进行了差异性分析,结果表明:①前期阶段黄芪种间根系结构差异不显著,在生长中后期(≥60 d),蒙古黄芪韧皮射线和木射线薄壁细胞中淀粉积累显著高于膜荚黄芪;②蒙古黄芪根系毛蕊异黄酮葡萄糖苷、刺芒柄花苷和多糖含量分别是膜荚黄芪的1.8倍、1.6倍、1.3倍;③膜荚黄芪根形畸变率(70%)远高于蒙古黄芪(53.1%),且膜荚黄芪和蒙古黄芪直根根形指数(RS1)置信区间分别为[0.77 0.82]、[0.74 0.79];④膜荚黄芪株高、地径、A/U值分别是蒙古黄芪的1.14~1.22倍、1.13~1.46倍、1.21~1.80倍,但根长却显著低于蒙古黄芪(P<0.05)。建议种植品种根据生产目标定向选择。

Abstract:

To clarify the interspecies difference of Astragalus has an important impact on its industrial planting, the differences between Astragalus mongolicus and A. membranaceus were analyzed including root structure development, root morphology, medicinal components and apparent growth respectively. The results showed that: ①On the early stage, there was no significant difference in root structure between Astragalus species, while sowing 60 d later, starch accumulation in phloem ray and xylem ray parenchyma cells of A. mongolicus were significantly higher than that of A. membrane. ②The contents of calycosin-7-glucoside, formononetin and polysaccharide in root of A. mongolicus were 1.8, 1.6 and 1.3 times as much as that of A. membranaceus, respectively. ③The root morphological distortion rate of A. membranaceus (70%) was significantly higher than that of A. mongolicus(53.1%), and the confidence intervals of the root shape coefficient(RS1) of A. membranaceus and A. mongolicus were [0.77 0.82] and [0.74 0.79], respectively. ④The plant height, ground diameter and A/U values of A. membranaceus were 1.14-1.22, 1.13-1.46, 1.21-1.80 times as much as that of A. mongolicusP<0.05), respectively, but the root length was significantly lower than that of A. mongolicus. Therefore, it is suggested that planting varieties should be selected species according to the production target.
