RELACION ENTRE LA RESPUESTA DE Canavalia ensiformis A LA INOCULACION MICORRIZICA Y ALGUNAS PROPIEDADES QUIMICAS DEL SUELO/Relationship between Canavalia ensiformis response to mycorrhizal inoculation and some chemical properties of soil

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. Key words: green manures, nutrient content (soil), organic matter, arbuscular mycorrhizae, soil pH En Cuba se han realizado investigaciones relacionadas con la inoculación de especies de hongos micorrízicos arbusculares (HMA) en diversos cultivos y tipos de suelo; encontrándose que, para un mismo tipo de suelo, la especie de mayor estimulación del crecimiento de la planta hospedante siempre es la misma, lo que ha permitido inferir que existe una alta especificidad en la especie eficiente de HMA por tipo de suelo. Este trabajo se realizó para evaluar si algunas propiedades del suelo tienen relación con la respuesta a la inoculación micorrízica de Canavalia ensiformis, cultivada en tres tipos de suelos. Se emplearon los resultados de experimentos conducidos en suelos Ferralítico Rojo Lixiviado, Gley Nodular Ferruginoso y Pardo mullido carbonatado. La canavalia fue inoculada con las especies Glomus cubense, Rhizophagus intraradices y Funneliformis mosseae. En todos los casos se empleó un diseño de bloques al azar con cuatro réplicas. Los
