The cultivation of the guava, in the last times has acquired a great importance in Venezuela and especially in the Monagasstate, mainly for its ascorbic acid content and for the profitable of the cultivation. Its fruit is used as raw material in theagroindustry and homemade candy store, which represents an important investment for the agribusiness of the cultivation.For that reason, it was carried out the present study with the objective of evaluating the development of the fruit of theguava and its physical and chemical properties under the conditions of savannas in the Monagas state. The experiment wascarried out in a guava plantation, using the Río Chiquito cultivate, at the Santa Barbara Experimental Station, of theInstituto Nacional de Investigaciones Agrícolas. 60 plants were selected, taking the date of beginning of the flowering; later,twenty branches were marked later when the floral opening happened the same day. At intervals of seven days, after thefloral opening, it was determined: dry and fresh weigh, polar and equatorial diameter of the fruits, acidity titratable, totalsoluble solids, pH and the days lapsed from the floral opening until the crop; beside, visual observations for the color. Theresults point out that the growth curve described for the fruit of the guava is a double sigmoid model, with three stages: oneof quick growth, followed by a slow growth and the last of exponential increase, where the fruits reach its physiologicmaturity. The content of total soluble solids, acidity titratable and pH increase starting from the last phase, which indicatesthat the fruit reaches its maturity. |
