PRELIMINARY RESULTS REGARDING THE INFLUENCE OF SOME FOLIAR BIOLOGICAL TREATMENTS ON THE PRESERVING CAPACITY AFTER HARVESTING OF THE APRICOTS

The paper presents the results obtained in 2018 on quality maintaining of the apricots varietiy 'Orizont'. The apricot trees were fertilized with the biological fertilizer Cropmax with was applied together with some biological fungicides, insecticides and/or acaricides in three variants: v1= Cropmax + Konflic + Funres; v2= Cropmax + Oleorgan + Canelys; v3= Cropmax + Canelys + Mimoten. Apricots were kept in different technological conditions: room temperature (20-22 degrees C), temperature of 10-12 degrees C (refrigerant conditions) and temperature of 3-5 degrees C. with and without modified atmosphere (cold storage), for 7; 15 and 30 days, respectively. the initial level and the evolution during storage of the firmness of the fruits were determined. After storage determinations were performed on the total losses, quantitative losses and qualitative depreciations. It was found that the quality of the apricots and their storage capacity vary according to the foliar biological treatments applied to the apricot trees and to the conditions in the storage environment. The v1 variant induces the best quality and storage capacity. Of the four studied storage methods, the best results were obtained within the cold storage with modified atmosphere, which recorded the smallest losses during storage.
