Influence of Rhizobium and Mycorrhizae in the Production of Seedlings of Caesalpinia Spinosa L. Taya in San Pablo, Peru

Abstract

Abstract This research study evaluated the symbiotic influence of Mycorrhizae in the production of propagating material of Caesalpinia Spinosa L. Taya, as well as the characterization of strains of mycorrhitic fungi in field, nursery, and laboratory work. No nodules were found as a product of nitrifying bacteria in the roots of plants Caesalpinea spinosa L., and ectomycorrhitic fungi were identified in the rhizosphere, such as Basidiomicetes and species of Rhizoctonia sp and Fusarium sp. From the evaluations, T4 exceeded all treatments, such as in height, neck diameter, number of leaves, root length, and the wet and dry weight of Taya seedling. In conclusion, we say that the Caesalpinia Spinosa L. Taya, despite of belonging to the legume family, does not present nodulation; but the presence of ectomycorrhitic fungi such as the basidiomicetes in the rhizosphere and high content of organic matter, positively influences the increase in the volume of seedling in the nursery, also reflected in the absorption of protein and phosphorus.
