摘要/Abstract

摘要： 研究了宿主植物对丛枝菌根（Arbuscular mycorrhizae，AM）真菌（Glomus mosseae）生长发育的影响。结果表明：温室条件下，4种宿主植物都能与丛枝菌根真菌共生，综合比较菌根长度、根外菌丝量及孢子数3项指标，高粱敖杂1号对真菌的生长发育最为有利。宿主植物菌根长度及根中的可溶性糖质量分数与根外孢子数呈显著正相关，而宿主植物中磷质量分数与菌根真菌的生长发育没有显著的相关性。说明不同宿主植物甚至同种宿主植物不同基因型的品种与丛枝菌根真菌的共生状况不同，宿主植物的菌根长度及根中可溶性糖质量分数对菌根真菌的生长发育有显著影响。

关键词: 宿主植物, 侵染率, 菌丝含量, 孢子含量

Abstract: The influences of four different host plants(Sorghum vulgare Pers.,Aoza1;Sorghum vulgare Pers.Kang4;Triflium repens L;Sorghum sudanende(Pip.)Staff) on the growth of Arbuscular mycorrhizal fungi Glomus mosseae was studied.The results showed that under greenhouse conditions,four different host plants were infected by Glomus mosseae successfully.By comparison of total length of external hyphae,colonized root length and spore content,Sorghum vulgare Pers.,Aoza 1 achieved the greatest mycorrhizal development among the four host plants.The length of colonized roots and the mass fraction of soluble sugar in roots were significantly and positively correlated to spore content in substrates.Nevertheless,the mass fraction of P in root was not significantly correlated to mycorrhizal development.The results suggested that the different host plant even the different genotype within same the host plant species have different growth effects with the same fungal isolate.The length of colonized roots and the mass fraction of soluble sugar in roots could influence the mycorrhizal development greatly.

Key words: Host plants, Root colonization, Hyphae content, Spore content
