Some quality properties of three sweet cherry (Prunus avium L.) cultivars during shelf life.

摘要

Quality (stem rupture force, firmness, tensile strength and penetration depth, TSS and percentage of decayed fruits) of 3 cherry cultivars (Van, Bing, 0900 Ziraat) during shelf life was determined. Cherries were kept at 20 +or- 1 degrees C and 60 +or- 5% RH for 7 days and quality changes were determined at 1-day intervals. Stem rupture force and firmness varied among cultivars, Van being the best, followed by Bing and 0900 Ziraat. Highest TSS content in fruits was obtained from 0900 Ziraat (14.62%), followed by Van and Bing (13.00 and 12.39%, respectively). At the end of the study, the lowest TSS content was obtained from Bing and the highest from 0900 Ziraat. The highest initial tensile strength was 1.024 MPa for Van at harvest. However, this cultivar had the lowest tensile strength (0.171 MPa) on the 7th day. cv. 0900 Ziraat had the lowest percentage of decayed fruits (8.38) and better quality results than the other cultivars under shelf life conditions.
