DE ASSIS SILVA, Samuel; BUCKER MORAES, Willian  y  SOARES DE SOUZA, Gustavo. Doses of calcium in the growth of the bean plant cultivated in nutritive solution, in the presence of aluminum. Idesia [online]. 2011, vol.29, n.3, pp.53-58. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292011000300008.

The objective of this study was to determine the effects of calcium on the growth of common bean plants (Phaseolus vulgaris L. cv. Talismã) in nutritive solution in the presence of aluminum. The experiment was performed in a greenhouse in the Centro de Ciências Agrárias da Universidade Federal do Espírito Santo in the municipal district of Alegre-ES. The bean plants were cultivated for 45 days in nutritive solution with increasing doses of calcium, in concentrations of0, 25, 50, 100 and 200 mg dm-3 and a unique dose of aluminum of 15 mg dm-3. The design used was completely random, with five treatments and three repetitions. The level of 100 mg dm-3 calcium favored the development of the radicular system and the above-ground part of the bean plants, inhibiting the toxicity of the aluminum.

Palabras clave : Phaseolus vulgaris L; calcium; aluminum toxicity; growth analysis.
