Abstract

The genus Rubus includes more than 300 species, of which the genus Rubus glaucus Benth (andean blackberry or blackberry from castile) is one of the most cultivated species and of greater economic interest in Ecuador, as it is not a climacteric fruit, it deteriorates rapidly giving as a result, considerable postharvest losses. Taking into account this situation, which is a problem for farmers who want their product to reach various places with the lowest rate of deterioration, a trial has been carried out in which aloe extracts were evaluated at a concentration of (60, 70, and 100%) and combinations of these extracts of aloe with Trichoderma, and a unique solution of Trichoderma powder dissolved in water using the technique of immersion of fruits to these extracts, where the number of blackberry fruits is not before and that presented gray mold and dehydration, it was also identified the sugar levels (Brix degrees) that increased when reaching 8 days, which is the time at which selected fruits arrived without presenting any unfavorable situation. The evaluations of the extracts to increase the useful life of the blackberry in postharvest were made by immersion using 20 fruits to subject them to the extracts and in this way wait and isolate the fruits that show some deterioration as the days pass As a result, the 60% aloe extract can be considered to increase the useful life of the blackberry, for the attack of phytopathogenic fungi such as gray mold (Botrytis cinerea), the Trichoderma extract 1gr/L had a considerable effect on this situation, while for the ethylene levels that increase its sugars, and remain stable so that they do not deteriorate more easily, aloe extract 60%, aloe extract 70% and Trichoderma + aloe al 100% were found to have an effect on this condition.
