Physiological parameters of some pomological species, for the initial moment before storage period-preliminary data

Abstract

Due to the high perishability of the fruits, new ways of decreasing the physiological processes rates during the storage period are tested. Depending on the pomological characteristics of the fruits, the water and soluble solids contentsare influenced by the respiratory intensityand transpiration rate. The aim of this study was to establish the values of the physiological parameters of organic fruits in view of subsequent correlations with the parameters determined during storage. The species chosen for this research were strawberries, blueberries, chokeberries, plums and apples. The respiration and transpiration rate are correlated with water content and soluble solids of the fruits. The differences obtained are explained by the different levels of maturation process and the fruit's large variability. The differences between the climacteric and non-climacteric fruits were pointed out in order to choose the best storage conditions for these.
