Quality and correlation of physical and chemical parameters of goiaba cultivar fruits

Abstract

The guava (Psidium guajava L.) is a fruit plant that is widely distributed in Brazil. In the state of Mato Grosso, the culture adapted well in an irrigated system, however, there are still few studies related to the quality of the fruits produced in the state. In this way the objective of this work was to evaluate the physical and chemical characteristics of guava fruits cultivated in the region of Tangará da Serra - MT and establish the correlation between these characteristics. A randomized complete block design with three cultivars (Rica, Ogawa and Paluma) was used, four replications with six plants, where the following characteristics were evaluated: fresh mass, length, diameter, length / diameter ratio, pulp percentage, Total soluble solids, titratable total acidity, pH and ratio. The fruits of the cultivars Paluma, Rica and Ogawa cultivated in Tangará da Serra-MT have quality both for the in natura market and for the industry, in addition, a correlation of the physical and chemical characteristics of the guava fruits was observed, allowing the use Of simpler feature evaluations to aid the selection process.
