Ponto de colheita e uso de Calcarea carbonica em bananas tipo maçã cultivar ‘brs princesa’

Abstract

Banana is the second main fruit produced in Brazil, being Bahia is the most producer state. The culture of banana, in this State, is the productive activities with the greatest economic and social expression. The mature point to harvest of fruits is the most important parameter for its final quality. And The objective of this study was to evaluate the influence of the harvest point and the use of homeopathy on the physico-chemical characteristics and the post-harvest life of 'BRS Princesa' apple banana. The fruits of the 'BRS Princesa' variety were obtained from the experimental area of Embrapa Cassava & Fruits, located in Cruz das Almas-BA. This research was conducted in two steps, in the first the ideal point of harvest of the banana 'BRS Princesa' was analyzed, the fruits were harvested at the first cycle at 84, 98, 112 and 126 days after inflorescence emission, to evaluate the physical-chemical quality and post-harvest shelf life of the fruits stored at room temperature. In the second step, the effect of the homeopathic Calcarea Carbonica on the dynamizations 12, 30 and 200 CH, on the physical-chemical attributes and shelf-life of fruits harvested at 98 days after the emission of inflorescence. After the harvest, the bunches were transported to the Postharvet Facility of Embrapa Cassava & Fruits where were realized the physical and chemical analyzes of the fruits. The statistical design was completely randomized. At harvest, the different harvesting points presented significant differences for the physical parameters: fruit diameter, pulp diameter, fruit weight, pulp weight and chemical parameters: soluble solids and soluble solids/ titratable acidity ratio. At maturity stage 6 the fruits presented significant difference for the physical parameters: fruit weight, fruit diameter, pulp weight, pulp diameter and chemical parameters: titratable acidity, however, it was not possible to establish if there is a better harvesting point for these parameters. However, the data allow us to conclude that the shelf-life varies according to the harvest point. The fruits harvested at 84 days are the better point for a longer period between harvest and commercialization, in other hand the fruits harvested at 112 days obtained a shorter shelf-life compared to the other treatments. The treatments with the use of Calcarea carbonica did not interfere in the physical-chemical characteristics of the fruits, however, Calcarea carbonica 12CH and the control presented differences as a function of the cycles. For shelf-life, in the first crop cycle, Calcarea carbonica showed a greater number of days until reaching the stage 6.
