| description | <p>Two soils from Cauca Department (Colombia) were pasteurized; soil analysis showed that they contained 3.0 and 9.0 ppm P, pH 4.8 and 6.2, respectively. They were fertilized with 0, 30 and 60 kg P/ha. Tomato plantlets var. Chonto Santa Cruz were inoculated with 11 VAM isolates of the CIAT VAM fungal germplasm and one VAM native fungi. Plantlets were grown in pots. Fifty two days after plants were harvested and height, dry matter, tissue analysis tor N, P, K, Ca, Mg and B was performed; fungus infection and health were determined. The statistical analysis showed that the major differences in this bioassay were due to a type of soils and their nutritional conditions. Plant dry matter and height increased with the increased levels of fertilizer. Best grow results were obtained with 60 kg P/ha. Dry matter, heigth and nutrient uptake (N, P, K, Ca and B) were significantly different between introduced VAM and the native fungi. VAM fungi isolates had different behavior in each soil. This confirmed the soil influence in the symbiosis effectiveness.</p><br><p>En condiciones de invernadero, en dos suelos del Departamento del Cauca (Colombia), previamente pasteurizados, con contenidos de P de 3.0 y 9.0 ppm y pH de 4.8 y 6.2 respectivamente, sujetos a fertilización con O, 30 y 60 kg de P/ha, se probaron 11 cepas de hongos micorrizógenos provenientes de diferentes regiones del país y con la flora nativa de cada suelo. Las plantas se cosecharon a los 52 días de transplante y se les determinó altura, materia seca, análisis foliar de N, P, K. Ca, Mg y B, infección por hongos micorrizógenos y sanidad del cultivo. Las mayores diferencias en este ensayo se debieron al tipo de suelo y sus condiciones nutricionales. La materia seca y altura de las plantas aumentaron en ambos suelos, al incrementarse la fertilización, los mejores resultados en desarrollo vegetativo y reproductivo ocurrieron con 60 kg de P/ha. En materia seca, altura y absorción de N, P, K, Ca, y B, hubo diferencias altamente significativas entre cepas introducidas y flora nativa. Las cepas variaron en su comportamiento en los 2 suelos, lo cual corrobora la alta influencia de este factor en la efectividad de la simbiosis.</p> |
