Mudanças na biometria da romã (cv. Molar) durante o desenvolvimento do fruto.

Abstract

Trade of pomegranate has increased and attracted the interest of fruit growers in Brazil, however knowledge of the quality and commercial viability of the fruit is incipient in our region. Thus, the objective was to determine the main changes in pomegranate biometrics, besides characterizing the maturation curve of the fruit produced in the semi-arid of Paraíba. A search was conducted in the commercial farm orchard Águas de Tamanduá, located in the municipality of Sousa-PB, period between September 2014 and June 2015, using the variety molar. Flowers were marked in the field and fruits collected periodicallt, from anthesis to ripening. We used the experimental design completely randomized, with ten treatments (10, 20, 30, 40, 50, 60, 70, 80, 90 and 100 days old fruit) and four replications constituited by the average of five fruits, derived from a sample (n = 20). Individually analyzed each season collection. They were evaluated diameters (longitudinal and transversal), fruit volume, fresh matter (fruit, seed, peel and seed still aryl) dry matter (fruit, seed and peel), and the juice volume.The fruits of pomegrade had a growth pattern in a double sigmoid curve. The growth of fruit has been featured in four phases: phase I, from anthesis to 40 days, characterized by the rise of fruit growth; phase II, from 41 to 59 days, in which there is stability in the fruit growth; phase III, 60 to 90 days, in which there is a return to fruit growth , culminating in the maturation and the phase IV, 91 to 100 days, declining phase culminating with senescence of fruit.
