摘要：研究接种3个AM菌株对5个种源麻楝幼苗生长的影响,结果表明:菌株90068×种源CH01菌根感染率为96.3%,感染率分级为5,菌根依赖性中等;菌株90068×种源CH27在生长生物量方面作用显著;麻楝幼苗接种5至6个月后,菌株90068×种源CH01生长促进作用显著增强;矿质元素吸收方面,菌株90068×种源CH13对磷元素的吸收显著高于其他接种处理。此外,菌株90036与菌株9004在接种后幼苗测定的各项指标中表现各有优劣。其中菌根合成、生物量和苗高增长方面,菌株9004优于菌株90036;而对于矿质元素的吸收,菌株90036要优于菌株9004。综合比较而言,供试菌株90068表现较优,为对5个种源麻楝幼苗生长效应最佳的菌株。
Three arbuscular mycorrhizal fungi（AM） isolates were used to inoculate Chukrasia tabularis seedlings of five provenances to investigate the effect of three AM isolates on C.tabularis seedling growth.The results showed that：the mycorrhizal colonization rate was 96.3%,belonging to classification class 5 and with intermediate dependency.There was significant association between mycorrhizal isolate 90068 and provenance CH01.The most significant seedling growth was achieved in provenance CH01 colonized with mycorrhizal isolate 90068 in 5-6 months.Mycorrhizal association between isolate 90068 and provenance CH13 significantly resulted in P uptake more than all other colonization combination.Isolate 9004 produced better mycorrhizal colonization,greater seedling biomass and height than isolate 90036 did,while,isolate 90036 resulted in a better nutrient uptake.Based on these results,isolate 90068 was selected as optimum AM isolate for seedlings of the five provenances.
