Relationship between Canavalia ensiformis response to mycorrhizal inoculation and some chemical properties of soil

Abstract

In Cuba, it have been carried out investigations related with the inoculation of species of arbuscular mycorrhizal fungis (AMF) in diverse crops and soil types, being that, for a same soil type, the species that bigger stimulation of the growth of the host plant is always the same, what has allowed infering that a high specificity efficient species of AMF exists for soil type. This work was carried out to evaluate if some properties of the soil have relationship to the response of Canavalia ensiformis to the AMF inoculation, cultivated in three types of soils. They were used the results of experiments conduced in Nitisol, Cambisol and Plintosol soils. The canavalia was inoculated with the species Glomus cubense, Rhizophagus intraradices and Funneliformis mosseae. In all the cases was used at complete randomized blocks design. The results of the behavior of the canavalia inoculated with the most efficient species and the chemical properties of the soil were processed by means of a correlation analysis through the coefficient of Pearson. Also, it was carried out an analysis of main components for all the valued indicators. It is demonstrated that the soil type, their nutrients content and the pH have a high relationship with the answer type found in canavalia, being therefore, the efficient specie that was different in each case, in correspondence with the chemical properties of the soil in each analyzed experimental situation.
