Resumo: | The objective of this work was to evaluate the effects of four plant regulators-2,4-D; NAA; GA3 and STIMULATE- on the physicochemical characteristics of the watermelon cultivars, Crimson Sweet and Charleston Gray. The experiment was carried out in the field of DTCS-UNEB, Juazeiro-Bahia, between January and April 2011. Polypropylene trays with Vivatto substrate were used to prepare the seedlings. The experimental design was in randomized blocks, with nine treatments and three replications; thus, three plants were placed in each plot, in soil of the type Neossolo Flúvico, totaling eighty-one plants useful for each area, which were irrigated by drip and fertilized by fertigation. The spacing was 3.00 m between lines and 0.80 m between plants. From the flowering of the plants, treatments were carried out with two concentrations for each plant regulator. For physical and chemical analysis the fruits were harvested from the 72nd day after flowering. The results were subjected to analysis of variance and the means compared by the Duncan test at 5% probability. It was found that treatments with 2,4-D caused weakness in the plants, leading some of them to death, which suggests a possible phytotoxic effect of this regulator in the concentrations used. Regarding NAA and the biostimulant, it was found that NAA promoted the inhibition of fruiting and the biostimulant did not promote the development of plants and fruits in relation to the control. GA3 increased soluble solids with a consequent increase in the “ratio”, contributing to the improvement in the taste of watermelon fruits. |

El experimento se realizó en el campo de DTCS-UNEB, Juazeiro-Bahía, entre enero y abril de 2011. Para la preparación de las plántulas se utilizaron bandejas de polipropileno con sustrato Vivatto. El diseño experimental fue en bloques al azar, con nueve tratamientos y tres repeticiones; así, se colocaron tres plantas en cada parcela, en suelo del tipo Neossolo Flúvico, totalizando ochenta y una plantas útiles para cada área, las cuales fueron regadas por goteo y fertilizadas por fertirrigación. El espaciamiento fue de 3.00 m entre líneas y de 0.80 m entre plantas. A partir de la floración de las plantas se realizaron tratamientos con dos concentraciones para cada regulador vegetal. Para el análisis físico-químico los frutos se recolectaron a partir del día 72 después de la floración. Los resultados se sometieron a análisis de varianza y las medias se compararon mediante la prueba de Duncan al 5% de probabilidad. Se encontró que los tratamientos con 2,4-D causaron debilidad en las plantas, llevando a algunas a la muerte, lo que sugiere un posible efecto fitotóxico de este regulador en las concentraciones utilizadas. Con respecto a NAA y el bioestimulante, se encontró que NAA promovió la inhibición de la fructificación y el bioestimulante no promovió el desarrollo de plantas y frutos en relación al control. GA3 aumentó los sólidos solubles con el consecuente aumento de la “proporción”, contribuyendo a la mejora del sabor de las frutas de sandía.O objetivo deste trabalho foi avaliar os efeitos de quatro reguladores vegetais- 2,4-D; NAA; GA3 e STIMULATE- nas características físico-químicas das Cultivares de melancia, Crimson Sweet e Charleston Gray. O experimento foi realizado no campo do DTCS-UNEB, Juazeiro-Bahia, entre janeiro e abril de 2011. Bandejas de polipropileno com substrato Vivatto foram utilizadas no preparo das mudas. O delineamento experimental foi em blocos casualizados, com nove tratamentos e três repetições; assim, três plantas foram colocadas em cada parcela, em solo do tipo Neossolo Flúvico, totalizando oitenta e uma plantas úteis para cada área, que foram irrigadas por gotejamento e adubadas por fertirrigação. O espaçamento foi de 3,00 m entre linhas e 0,80 m entre plantas. A partir da floração das plantas, foram realizados os tratamentos com duas concentrações para cada regulador vegetal. Para as análises físicas e químicas os frutos foram colhidos a partir do 72º dia após a floração. Os resultados foram submetidos à análise de variância e as médias comparadas pelo teste Duncan a 5% de probabilidade.
