Evaluation of feijoa fruits from two experimental orchards in the middle west of Santa Catarina, Brazil

Abstract:

The aim of the present study was to determine the behavior of physicochemical characteristics of feijoa fruits of seven genotypes grown in two locations of Santa Catarina. The evaluation was made using the following: (i) 2011/12, 2014/15 and 2015/16 harvests of genotypes 85, 101, 223, 458 and 509, cultivated in Fraiburgo (Papuã community); and (ii) 2014/15 and 2015/16 harvests of genotypes 28.12 and 527, in Água Doce (Vista Alegre community). Diameter (cm), length (cm) and weight (g) of the fruit, peel (g) and pulp (g) weight, peel thickness (mm), and total soluble solids (Brix grade) were evaluated. An analysis of variance, comparisons between means using Tukey’s test (p < 0.05), and Pearson correlation coefficients (p < 0.05) were computed for the variables of feijoa fruits. In Água Doce, genotype 527 had the largest diameter and weight of the fruit (88.7 g). In Fraiburgo, genotype 85 had the highest fruit weight (94.9 g) and genotype 509 had the highest pulp yield (37.5%). Not all genotypes with higher fruit weight exhibited higher pulp yield, confirming that the skin thickness and fruit size variables are directly related to yield. The variation in total soluble solids values was due to the environment and genotype effects.
