Preservation of blueberry fruits depending on varietal specificity and meteorological conditions of the season

Abstract

On the basis of five-year data, the characteristics of berry storage life of 15 highbush blueberry cultivars and of a single lowbush blueberry cultivar under normal gaseous environment at the temperature +4 °C are given. The postharvest life of blueberry fruits is a labile index, varying significantly over the years, and depends on a cultivar, it ranges from 25 (Chanticleer) to 51 (Brigitta Blue) days at 90 % fruit output for cultivars of highbush blueberry, and 23 days for lowbush blueberry cultivar Putte. The postharvest life of blueberry fruits is a cultivar specific trait dependent on maturity of a cultivar: late- ripening cultivars have a longer storage period. Storage life of blueberries is shown to be dependent on the meteorological conditions during a season. To the greatest extent, the fruit keeping quality of this crop is effected by the distribution of precipitation during the period of growth and ripening of the crop. The hydrothermal conditions of the season to a greater extent affect the persistence of late-ripening blueberry cultivars.
