摘要

目的：观察丛枝菌根（AM）真菌在人工栽培条件下对掌叶大黄根和根茎的产量及化学成分含量的影响。方法：通过室内盆栽对照试验，设不接种AM组为CK组，设接种摩西斗管囊霉（Funneliformis mosseae）为AM组，每处理组重复15盆，每盆播种掌叶大黄种子10粒，出苗后间苗3株。采用文献方法计算菌根侵染率和浸染强度，采用称重法测定掌叶大黄根和根茎产量，采用高效液相色谱法测定掌叶大黄根和根茎中蒽醌类成分的含量，比较施加AM真菌后，掌叶大黄生物量、蒽醌类组分的变化。结果：AM组与CK组的侵染率分别为（96.96±1.57）%和0，侵染强度分别为（62.07±3.40）%和0；与CK组比较，AM组根和根茎产量提高了（42.96±2.12）%，总蒽醌类平均值提高了127.43%，差异均有统计学意义（P<0.05）。HPLC分析结果表明，AM组与CK组掌叶大黄蒽醌类在含量和成分间的比例上发生了一定的变化，但接种AM真菌处理并未导致掌叶大黄有效成分的根本改变。结论：接种AM真菌后，能明显促掌叶大黄根和根茎的生长发育，增加药用部位中有效成分的含量，但在试验期间未造成掌叶大黄质量的变异。

Abstract

Objective: To observe the effect of arbuscular mycorrhizal (AM) fungi on the yield and chemical composition contents of root and rhizome of Rheum palmatum in artificial cultivation. Method: Through pot experiment in room

not inoculated AM fungi group was regarded as CK group

inoculated Funneliformis mosseae fungi as AM group

15 pots repeated in each group

each pot planted 10 seeds

3 strains were kept on in each pot when the seedlings came out. Literature establishment method was used to calculate the mycorrhizal colonization rate and colonization intensity

weighing method was adopted to determine the yield and HPLC was conducted to determine the contents of anthraquinones in root and rhizome of Rheum palmatum

then the change of the biomass and anthraquinones in R. palmatum was compared between CK group and AM group. Result: Colonization rate of AM group and CK group were (96.96±1.57)% and 0

colonization intensities were (62.07±3.40)% and 0.Compared with CK group

the yield increased (42.96±2.12)%

the average content of total anthraquinones increased 127.43% in AM group

there were statistical significances in difference (P<0.05).The result of HPLC showed that

there was a certain change on the contents and composition ratio of anthraquinones between AM group and CK group

but inoculation of AM fungi did not lead to fundamental change on the effective components in R. palmatum. Conclusion: It could obviously promote the growth and increase the contents of effective components in root and rhizome of R. palmatum after AM fungi were inoculated

however

the kinds of anthraquinones showed no difference.
