Características nutracêuticas de pessegueiro cultivar Brs Rubramoore sob diferentes sistemas de condução

Abstract

The peach tree has great importance for the southern region, especially for Rio Grande do Sul, which is the largest national producer. The peach has great nutritional and economic importance, and can be consumed both fresh and processed. This work aimed to evaluate the nutraceutical and post-harvest characteristics of the BRS RubraMoore cultivar, grown under different conduction systems. Seven conduction systems were evaluated, in open vase or bowl, in "Y" (ipsilon), in central leader, in 'Double Leader', in 'Triple Leader', in 'Quadruple Leader' and Guyot or multiple leaders. The experiment was conducted in 2021/2022 in peach orchard in its second year after deployment (2022), located in the experimental area of the Universidade Federal da Fronteira Sul - UFFS, Campus Chapecó-SC. Total soluble solids (°Brix), total and reducing sugars, vitamin C and total phenolic compounds were evaluated. The data obtained were tested for normality and homogeneity by the Shapiro wilk test and later submitted to the analysis of variance Anova and, when significant, submitted to comparison using the Tukey test at 5% probability. These were analyzed using the statistical program "R". The variables soluble solids and vitamin C showed no significant difference in all analyzed conductions, the other variables analyzed as: total phenolic compounds and total and reducing sugars showed significant difference, the conduction that showed superior results to the others was the triple leader.
