Abstract

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
