Summary
The objectives of this research were to perform the physical, chemical and sensorial characterization, for hybrid and open pollinated tomato, within the Santa Cruz and Italian groups, aiming fresh consumption. A total of 14 fresh market tomato cultivars was used, six of them being experimental varieties and eight were commercial ones. The experimental design was of randomized blocks with six replicates and five plants per plot. For the chemicophysical analysis, samples of ripe fruits were randomly extracted from five plants in each plot, labeled and maintained under refrigeration at 5ºC until the next day after harvest. Afterwards, fruits of all cultivars were mixed, ground and divided in triplicates to be submitted to the physicochemical analysis. From the physicochemical analysis it was observed that the value of the ratio between soluble solids (SS)/titratable acidity (TA) was higher in the cultivars IAC 6 and IAC 3. In relation to the SS content, the highest values were obtained by cultivars IAC 1 and IAC 6. In order to evaluate the commercial value of the cultivars, a sensorial analysis was carried out with fruits tasted by 75 individuals, using a hedonic scale of seven points. The data were analyzed by variance analysis and grouping of means. The cultivars of the Italian group IAC 4, IAC 6, Netuno and Bari; as well as the cultivars of the Santa Cruz group IAC 1, IAC 5, HTV 0601 and Débora Victory reached the best scores in all the sensorial traits evaluated. All the cultivars presented reasonable quality of the fruits, with SS/TA ratio values higher than 16 and SS values higher than 4ºBrix.
Summary translation
Os objetivos do trabalho foram caracterizar física, química e sensorialmente os frutos de tomate de cultivares híbridas e de polinização aberta, dentro dos grupos Santa Cruz e Italiano, visando o consumo in natura. Utilizaram-se 14 cultivares de tomate de mesa, sendo seis experimentais e oito comerciais. O delineamento experimental foi de blocos casualizados com seis repetições e cinco plantas úteis por parcela. Para as análises físico-químicas, as amostras dos frutos vermelhos maduros foram retiradas aleatoriamente de cinco plantas de cada parcela, etiquetadas e mantidas sob refrigeração a 5ºC até o dia seguinte à colheita. Em seguida, os frutos de cada cultivar foram misturados, triturados e divididos em triplicatas para as análises físico-químicas. Verificou-se que o valor da relação sólidos solúveis (SS)/acidez titulável (AT) foi maior nas cultivares IAC 6 e IAC 3. Com relação ao teor de SS, os maiores valores foram obtidos pelas cultivares IAC 1 e IAC 6. Para constatar a aceitação pública das cultivares, foi realizada uma análise sensorial dos frutos com 75 provadores, utilizando-se uma escala hedônica de sete pontos. Os dados foram submetidos à análise de variância e agrupamento de médias. As cultivares do grupo Italiano IAC 4, IAC 6, Netuno e Bari; bem como as cultivares do grupo Santa Cruz: IAC 1, IAC 5, HTV 0601 e Débora Victory obtiveram as melhores notas em todos os atributos sensoriais avaliados. Todas as cultivares apresentaram frutos de qualidade, com valores da relação SS/AT maiores que 16 e teor de SS maior que 4ºBrix.
