Allometric determination between mineral absorption and biomass in different cultivated species. Cien. Inv. Agr. (in English) 33(1):59-63.

摘要: The fitting coefficients to relate nutrients relative absorption and biomass in seven different vegetable fruit crops were determined, using the potential M·M T - 1 = M O (B·B ) b equation where M= nutrient amount crop biomass, B; total contained B ; normalization constant, allometric exponent. Nutrients data of previously published experiments examined. goodness indicators showed that this function related both variables satisfactorily. In cases, absolute sum squares varied between 0.0009 y 0.084, standard deviation residues 0.008 0.2 over adjustment values. Correlation coefficient values higher than 0.9 always obtained. constant was found be close unit, so being assumed equal 1.0, along with determination exponent for macronutrients. characterized curvature each nutrient. Se determino los coeficientes de ajuste para relacionar la absorcion relativa nutrientes biomasa en siete diferentes cultivos horticolas frutales, empleando ecuacion potencial, (M cantidad nutriente del cultivo, totales contenidos constante normalizacion, exponente alometrico). examino datos experimentos previamente publicados. Los indicadores bondad mostraron que esta funcion relaciono satisfactoriamente ambas variables. En casos suma cuadrados absoluta vario entre 0,0009 0,084 desviacion estandar residuos 0,008 0,2 sobre el valores relativos. Siempre se obtuvo coeficiente correlacion mayores a 0,9. Junto determinacion alometrico macronutrientes, encontro aproximo unidad, pudiendo asumirse igual 1,0. El caracterizo curvatura cada nutriente.
