The research was carried out with sour cherry cultivars ‘Alfa ̓ and ‘Pamiat Artemenko ̓ at the experimental pomology station named after L.P. Symyrenko of the institute of horticulture of NAAS. The pre-harvest treatment of sour cherry fruit with mixture of 1 %-chitosan with 100 mg l-1 of salicylic acid appeared to be efficient; this makes it possible to extend the storage period up to 30 days, to increase the output of marketable produce by 7.8–8.6 %, to have mass losses which do not exceed 3 %. The pre-storage treatment of sour cherry fruit with the solution of salicylic acid in combination with chitosan facilitates the decrease of the number of mesophylic aerobic and facultative anaerobic microorganisms by 5.2 times, that of yeast and mold – 6.3 times. Along with this, taste properties of the produce are maintained at the level of fresh fruit, also the product has an excellent tasting evaluation – 5 points.20252025-07-16 12:27:29Članek v reviji170804sl
