QUALIDADE DOS FRUTOS DO HÍBRIDO DE TOMATE PARA PROCESSAMENTO INDUSTRIAL H9992 EM DIFERENTES PERÍODOS DE COLHEITA

Abstract

As a result of the various discounts caused in the process of classification of the industrial tomato fruits, it is necessary to choose the harvest season that preserves the quality of the raw material as much as possible. The objective of this work was to observe the effect of the harvest period of the Heinz 9992 hybrid on the physicochemical qualities of the fruits destined for industrialization, and in this way to identify the ideal moment for a greater yield of the raw material. The treatments consisted of evaluating the harvest in four different time intervals, at 97, 104, 111 and 118 days after transplantation (DAT). The harvest carried out at 97 DAT provided a higher soluble solids content, showing dissimilarity when compared to the other times and a higher firmness value of the fruits, however the highest number and weight of green fruits was obtained, and ° Hue below that indicated for culture. At 104 and 118 days, a greater number and weight of discolored and disintegrated tomatoes was detected, respectively. On the other hand, at 111 days a greater maturity uniformity of the harvested fruits was reported, in addition to being adequate to the main desirable requirements for industrialization. Yield was not affected in relation to the harvest season. The harvest periods analyzed for the Heinz 9992 hybrid influenced all the physical-chemical characteristics of the crop and its industrial parameters, except for productivity.
