Abstract (es)

Tests were carried out under greenhouse conditions in Tunja (Colombia) in order to evaluate the effect of Fe2+ toxicity on the growth of broccoli plants. 'Legacy' hybrid Brassica oleracea var. Italica plantlets were grown in glass containers with a nutritive solution. Iron sulfate was added to the substrate in order to produce excess iron at concentrations of 100 and 200 mg L-1; a control without iron sulfate applications was used. The following evaluations were made: leaf area, total dry weight of the plants, distribution of dry mass (DM) in the different organs, absolute growth rate, relative growth rate, net assimilation rate and the root:shoot ratio. The total DM decreased drastically in the plants subjected to excess Fe2+, the growth indices progressively decreased with increases in the Fe2+ concentrations in the substrate and the distribution of DM in the organs varied as a function of the needs of the plants, with 15.85 and 11.10% less DM in the roots of the plants subjected to Fe2+ than in the control plants, at 100 and 250 mg L-1, respectively.

Con el objetivo de evaluar el efecto de la toxicidad por Fe2+ sobre el crecimiento de plantas de brócoli, se llevó a cabo un ensayo bajo condiciones de invernadero en Tunja (Colombia). Se utilizaron plántulas de Brassica oleracea var. Italica híbrido 'Legacy', sembradas en contenedores de vidrio con solución nutritiva. Se adicionó sulfato de hierro al sustrato para inducir el exceso del metal, en concentraciones de 100 y 250 mg L-1 y un control sin aplicación de sulfato de hierro. Se evaluó el área foliar, el peso seco total de la planta y la distribución de la materia seca (MS) en los diferentes órganos, se calculó la tasa de crecimiento absoluto, tasa de crecimiento relativo, tasa de asimilación neta y la relación raíz:vástago. El peso seco total disminuyó drásticamente en las plantas sometidas a exceso de Fe2+, los índices de crecimiento disminuyeron progresivamente a medida que aumentó la concentración de Fe2+ en el sustrato y la distribución de la MS en los órganos varió en función de las necesidades de la planta, siendo 15,85 y 11,10% menor la proporción de MS en las raíces de las plantas sometidas a toxicidad por Fe2+ que en las plantas control, para 100 y 250 mg L-1, respectivamente.
