| 1 | Identification of Arbuscular mycorrhizal multiplicity in the saline-sodic soils显示文摘This study focused on the Arbuscular mycorrhizal(AM)fungal diversity in the saline-sodic soils based on native spore density and most probable number(MPN)assay.Identification through spore morphology showed existence of five genera in the various crop rhizospheres.The physico-chemical analysis of the native soils revealed that they were saline-sodic with pH ranging from(8.7±0.5)to(9.5±0.6)and habituated five different genera of AM fungi including Glomus,Scutellospora,Acaulospora,Sclerocystis and Gigaspora.Each location revealed presence of varied species of AM fungus namely Acaulospora and Glomus in rhizosphere of maize;Scutellospora and Glomus in tulsi;four isolates of Glomus in onion;Glomus and Sclerocystis in guava;three isolates of Glomus in rice;Glomus in neem and Gigaspora and Glomus in bamboo.The molecular identification through nested PCR analysis showed amplification of 600 bp size in SSU rDNA gene in samples A and C(predominated by Acaulospora and Glomus mosseae respectively). | Srimathi Priya L Kumutha K Arthee R Pandiyarajan P | 2014 | International Journal of Agricultural and Biological Engineering2014，7，2： | 0 |
