Japanese plum performance assessment(Prunus salicina Lind.) cultivar byron in the municipality of Ponta Grossa-PR.

Abstract

The temperate climate fruit crop in Brazil occurs mainly in the South region, being one of the limiting factors for the increase of the productive area of these fruits the small amount of cultivars adapted and available to the producers. The objective of this work was to analyze the performance of a cultivar developed in the United States, aiming to adapt to the climate of the Campos Gerais region in Parana. This work was carried out during the years 2013 to 2015, in which the phenological evaluations analyzed were: beginning and end of flowering and fruiting; on the fruits, it was evaluated: diameter (DM), fruit weight (PF), stone weight (PC), mass of fruits (MF), total soluble solids (SST), total titratable acidity (ATT), ratio (RAT) and pH. The phenological results obtained related to the production cycles show that this introduction in the region presents the fruit harvest in December and the physical and chemical characteristics present in the fruits present a quality equal to or higher than those obtained in cultivars already available in the market. Through the study it is possible to recommend planting for the Campos Gerais region in Parana and other studies with introduction in other regions of the state are recommended.
