Evaluation of the population of mycorrhizas in potato plots (Solanum tuberosum L.) In the bolivian central altiplano

Abstract

A study of the ocurrence of mycorrhiza (MVA fungi– Micorriza Vesiculo Arbuscular because its Spanish acronyms) in potato plots (Solanum tuberosum) has been carried out to find the relationship of the behaviour of mycorrhiza with the precipitation and soil gravimetric humidity. It was found that the population range of spores in the rhizospheric soil of these plots ranges from 684 to 652 spores for 100 g of dry soil. Also, when analysing the relationship between the number of spores and precipitation an asymptotic relationship could be observed. The relationship between the yield of the potato and the number of spores in this research environment was not significant, but a positive slope show, which would indicate an indirect effect on the production.
