Résumé:
The aim of this study was to identify and quantify fungal post harvest occurred in two cultivars of banana (cv. Prata and cv. Maçã ) marketed in the open street of Sumé - PB and to check differences between cultivars in the incidence of these fungi. The collected bananas had degree of ripeness type 6 (fruit peel completely yellow). The collections were made once a month during a six-month period, from July 2012 to January 2013. All collections in different months were made in three fixed points of marketing. We used two banana cultivars 'Prata' and 'Maçã'. Identification and frequency of fungi were conducted by isolation, made by plating the fragments of fruits that presented symptoms of diseases and / or signs of pathogens. The experimental design was a randomized block design (RBD), with three replications, each replicate consisting of a point of sale. As treatment, was considered the banana cultivars. The fungi identified in this study were: Colletotrichum musae and Fusarium spp., Possible causes of disease and opportunistic fungi Penicillium sp., Aspergillus niger and Rhizopus sp. Among the pathogens detected, Colletotrichum musae even did not differ statistically from Aspergillus niger and Penicillium sp. stood among the largest magnitude over the frequency of attack in the fruits in both cultivars (27.44% -Apple and 33.13% Silver). The banana cultivars (apple and Silver) did not differ statistically, F-Snedecor test at the 5% level, between the overall averages for the months of evaluation for the different fungal genera identified.
