This study designed to investigate more precise of mycorrhizal symbiosis in order to increasing mineral absorption by plant root system. Three pot experiments, radioactive with 32P, non-radioactive and a trial with selected strain (from first and second trials) with heavy metals (Cd, Co and Pb) contaminated soil were set up for evaluation the efficacy of four mycorrhizae strains including Glomus mosseae, G. etanicatum, G. intraradices, mixed strains (combination of G. mosseae, Gigarpora hartiga and G. fasciculatum) in order to investigate the uptake, translocation and distribution of 32P, P and also dry matter in barely in a glass house. Radioactive phosphorus (32P) was used in this study. Results revealed that G. mosseae had the highest amount of P uptake in comparison with other strains. It indicates that differences exist among mycorrhizae strains towards 32P uptake and its transportation to shoot. Increased strain count of G. mosseae was found in contaminated pots in trial with contaminated soil along with higher P concentration in root and shoot than non-inoculated plant roots. |
