Abstract
El presente trabajo tuvo como objetivo determinar algunas propiedades físicas y fisiológicas de la ciruela variedad Horvin, durante el periodo precosecha, cuyo conocimiento es indispensable para la determinación del momento oportuno de recolección, lo cual permitirá reducir las pérdidas que se presentan de este producto durante la cosecha, debido a su deficiente manejo. El estudio permitió determinar que la ciruela variedad Horvin debe recolectarse 99 días después de la floración, en cuyo momento presentó valores medios de firmeza de 50,66 N, acidez titulable de 0,78%, sólidos solubles de 11,8 ºBrix, intensidad respiratoria de 19,64 mg CO2 kg-1 h-1 y relación de madurez (SS/AT) de 15,25. La ciruela variedad Horvin en el momento de la recolección, presentó un tamaño medio de 30,59 mm, peso de 22,44 g, esfericidad y redondez de 0,84 y 0,85 respectivamente, densidad real de 1095,65 kg.m-3, densidad aparente de 572,70 kg.m-3, porosidad de 49,89% y área superficial de 32,79 cm².
This research was carried out to determine some physical and physiological properties of plum (Prunus domestic L.) cv. Horvin, during the pre-harvests period, whose knowledge is indispensable to determine the appropriate harvest time, which will allow reducing the losses of this product during the harvest, due to his deficient handling. The study allowed determining that the plum cv. Horvin must be harvest 99 days after flowering. The fruit in this stage presented values for flesh firmness of 50.66 N, titratable acid of 0.78%, Soluble Solids of 11.8 ºBrix, respiratory rate of 19.64 mg CO2 kg-1 h-1 and relation (SS/AT) of 15.25. At harvest time the fruit present size about of 30.59 mm, weight of 22.44 g, sphericity and roundness of 0.84 and 0.85 respectively, real density 1095.65 kg.m-3, apparent density of 572.70 kg.m-3, porosity of 49.89% and superficial area of 32.79 cm².
