- W2890515904 abstract "espanolRESUMEN Con el aumento de la superficie cultivada de tomates de pequeno diametro, es necesario establecer una normativa de clasificacion para su comercializacion. El objetivo del estudio es proponer una clasificacion para tomates tipos Cereza y Grape en funcion al tamano de los frutos, el efecto del sistema de cultivo y la intensidad del deshojado. Se cultivaron tomates tipo cereza Wanda y tipo Grape Dolcetto, bajo dos sistemas cerrados de cultivo sin suelo (canales y macetas). Se utilizo cascara de arroz in natura como sustrato, con tres intensidades de deshojado (plantas con el simpodio completo; una y dos hojas eliminadas por simpodio). Para la clasificacion de los frutos, se utilizo dos series de cinco tamices con mallas de perforaciones adaptadas a cada variedad. Se seleccionaron las siguientes mallas: para Cereza 35, 30, 25, 20 mm y recolector, y para Grape 25, 20, 15, 10 mm y recolector. A partir del inicio de la recoleccion de los frutos se han evaluado las variables numero y peso medio de los frutos retenidos en cada uno de los tamices para cada una de las variedades. Se evaluaron 8.284 frutos del tipo Cereza y 8.033 del tipo Grape durante siete meses de cosecha. Los datos sometidos a un analisis de varianza, regresion lineal; las medias fueron comparadas con la prueba de Tukey. Los resultados indicaron que el deshojado disminuyo la cantidad de frutos clasificados como grandes para ambas variedades. El sistema de canales favorecio la produccion de frutos clasificados como grandes para la variedad Grape. Los tamices 1, 2 y 3 fueron adecuados para la clasificacion de los frutos de ambas variedades. Es posible ordenar el tamano de frutos de tomates con el uso de tamices especificos para cada tipo de variedad. EnglishABSTRACT With the advancement of small size tomato cultivation in recent years, studies on fruit grading are necessary to obtain a commercialization standard. Therefore, the objective of the work was to perform the grading, based on the fruit size of Grape and Cherry mini tomatoes, considering the effects of different cropping systems and defoliation levels. Tomato plants of Wanda Cherry Hybrid® and Dolcetto Grape Hybrid® varieties were grown in two closed soilless systems (troughs and pots), using substrate of raw rice husk, under three different defoliation intensities (without defoliation, removal of one and two leaves of the sympodium). For fruits grading, two sets of five sieves were used, with mesh drilling adapted for each variety. The chosen meshes were: 35, 30, 25, 20 and 0 mm for Cherry, and 25, 20, 15, 10 and 0 mm for Grape. From the beginning of the fruit harvest the variables of number and mean weight of fruits retained in each of the sieves were evaluated, for each variety. A total of 8284 fruits of the Cherry type and 8033 fruits of the Grape type were evaluated during seven months of harvest. Data were submitted to analysis of variance, linear regression, and comparison of means by the Tukey test. The obtained results indicated that defoliation reduced the amount of fruits grading as large for both Cherry and Grape varieties. The troughs system benefited the production of Grape variety fruits grading as large. The sieves 1, 2 and 3 are suitable for the fruits grading of both varieties. The grading of mini tomato fruits with the use of specific sieves for each type variety is feasible." @default.
