Influência de altas temperaturas na floração, formação e produção de feijão carioca

Abstract

The carioca beans, in a special way, are present in the diet of Brazilians as an important source of vegetable protein, carbohydrates, fibers and vitamins such as the b-complex. Ceiling the evident exponential growth of the Brazilian population that we have seen nowadays, it is observed that it is necessary to study and improve the practices and technologies used in the cultivation of beans in Brazil, so that in this way the grain production can be achieved. It is known that one of the limiting factors for the maximum development and success of the bean crop are environmental factors such as water deficit and especially highs caused by high daily solar radiation, which cause, in addition to other problems, the abortion of flowers and pods, causing several losses in production and productivity, often making its cultivation unfeasible in some regions. The aim of this study was to carry out a bibliographical survey on the climatic factors that most interfere in the productivity of the bean plant, specifying the abortion of flowers and pods caused by the high temperature in Brazilian bean-producing regions, as well as highlighting and discussing the need of behavioral studies of bean cultivars according to the region to be inserted in a crop.
