- Abstract
The objectives of this work were to evaluate the phosphorus partition in tissues, in different growth stages, the phytic acid concentration in grains and the beans yield, as a response to the phosphorus supply in the culture environment, and the analysis of the association between these characters. The experiments were conducted in non-acclimatized greenhouse. The data was submitted to variance analysis, considering all the effects as fixed, with exception of the error, which was considered random. Since it was significant the effect of the triple interaction phosphorus concentration x genotype x growing season (C x G x E), it was realized the deployment of it in three double interactions with the use of complex variance. The phosphorus values in common bean leaves at initial growing stages are close to the ones found in grains. For the genotypes Pérola and IPR88 Uirapurú, the highest phosphorus values in plants tissues and of phytic acid occurred in phosphorus concentrations in the nutritive solution between 1.38 and 2.00 mmol L-1. Phosphorus concentrations in the nutritive solution between 1.37 and 1.96 mmol L-1 result in higher phosphorus concentration in leaves at third trifoliate leaf, in stem at flowering, in leaves, stem and legumes at legumes filling and grains at maturation. Also, higher phytic acid concentration in grains, at the fall-winter and spring-summer seasons. The evaluation of phosphorus concentration in the vegetal tissues from the legume filling stage is promising and allows indirect selection to grains productivity.
