Response of bean cultivated in nutrient solution to levels of calcium and magnesium in the presence of aluminium

Response of bean cultivated in nutrient solution to levels of calcium and magnesium in the presence of aluminium

An experiment was carried out under greenhouse conditions utilizing the Milionário Mulatinho cultivar, to evaluate the effects of Ca and Mg levels, in nutrient solution containing Al, on the dry matter and content of nutrients in shoot and roots of bean (Phaseolus vulgaris L.). The experimental design consisted of an incomplete factorial with four levels of Mg and five levels of Ca, in the presence of 3.0 mg/L Al, and of a control (without Al), being as a whole ten treatments with three replications. Each vase had 4.8 L of ½ - power Clark solution, pH 4.5, and two plants of bean. The presence of Al reduced the production of dry matter of shoot and the uptake of Ca, Mg and P. On the other hand, the accumulation of P and Al in the roots was increased and the accumulation of K and dry matter in that part of the plant was unaffected by Al. The supplying of Ca in the nutrient solution increased the production of dry matter in the roots and, in a general way, it also increased the concentration and accumulation of nutrients in the plants. The increase of Mg in nutrient solution increased its accumulation by plant and the production of dry matter in shoot. The concentrations of Ca and Mg in solution positively interacted with P concentration and with the accumulation of P and Al in the root system.

Realizou-se experimento em casa de vegetação, com o objetivo de avaliar o grau de acumulação de matéria seca e de nutrientes na parte aérea e nas raízes de plantas de feijão (Phaseolus vulgaris L.), com o aumento da concentração de Ca e Mg em solução nutritiva contendo Al. Utilizou-se um fatorial incompleto com quatro níveis de Mg e cinco de Ca, na presença de 3,0 mg/L de Al, acrescido de um tratamento-testemunha (sem Al), perfazendo um total de dez tratamentos, com três repetições. A unidade experimental foi formada por vaso contendo 4,8 L de solução de Clark - ½ força, pH 4,5, e duas plantas de feijão var. Milionário Mulatinho. A presença de Al diminuiu a produção de matéria seca da parte aérea e a absorção de Ca, Mg e P pela planta, porém aumentou o P e o Al no sistema radicular e não afetou a produção de matéria seca e o K nas raízes. O fornecimento de Ca em solução aumentou a produção de matéria seca das raízes, e, de modo geral, os nutrientes na planta. O aumento do Mg em solução favoreceu seu acúmulo na planta e a produção de matéria seca da parte aérea. Os teores de Ca e Mg na solução interagiram positivamente com o teor de P e com os conteúdos de P e Al no sistema radicular.
