Abstract

One of the main requirements of modern intensive orchards is that every year they give rich and good yields. Fruit quality has an impact on the environment, depending on the local soils and climate. Apple retention depends on the room temperature, relative humidity, and composition. Investigations were carried out in 2012–2013. Apples grown in Ilgalaukių village, Rokiskis area. Apples harvested 22 09 month 2012. After harvest fruits were storage at 0–3 °C temperature and 90–95 % relative humidity. The aim of the study was to determine changes of ʽAlvaʼ, ʽŠampionʼ, ʽRubinʼ apples quality during storage. Chemical analyses were done four times every 60 days, from September to April. The highest dry matter and soluble dry matter content was determined in ʽAlvaʼ apples, respectively, 28.41 and 32.52%. The least titratable acidity after 6 months storage was set in ʽRubinʼ apple fruit, and the highest in ʽŠampionʼ apples
