Aplicação de benziladenina em cultivares arbustivas de feijão-vagem

Abstract

The snap bean is a vegetable of the same botanical species of common bean (Phaseolus vulgaris L.) and is characterized by being harvested when the pods are still green, being cultivated in several Brazilian regions. In the pod formation stage may occur to fall thus reducing productivity. As an alternative to prevent the loss in productivity, we evaluated the performance of benzyladenine in the sett, pod development and seed quality in seven shrub cultivars of snap bean: Delinel, Derby, Festina, Improved Gold Wax, Jade, Provider; Yellow and Japanese. The experiment was divided into two phases, both conducted at the State University of Goiás, Campus Ipameri; in the field it was used a randomized block with seven (cultivars) and the treatments arranged in split plots (treatments with and without benziladelina and subplots four replications). The cultivars were evaluated for stem diameter, number of days to flowering, plant height during the commercial pod harvest, the number of green and dry pods per plot data on the final plant stand, the number of dried pods per plant, seed yield; laboratory were determined the mass of 100 seeds, germination percentage and germination speed index. It was observed that there was no interaction between cultivars and benzyladenine, among the variables analyzed in the field. As for the quality and vigor, only to cultivate Delinel without presence of benzyladenine, it proved to be different from the others with a lower percentage of germination
