Karina Juhnevica, Liga Skudra,Mara Skrivele, Dalija Seglina, Gita SkudraPRELIMINARY RESULTS OF 1-METHYLCYCLOPROPENEINFLUENCE ON APPLE QUALITY DURING STORAGEConclusionsModified environment slows down the agingof apples thus changes in their quality during thestorage are minimal, especially in winter cultivars‘Belorusskoje Malinovoje’, ‘Antej’, ‘SinapOrlovskij’, and ‘Zarja Alatau’ treated with 1-MCPbefore the storage in ULO 2-type plastic bags with thefollowing gas content: O 2(1.50%) and CO 2(2.50%).Examination of the results revealed that physicochemicalindexes changed the most in samples storedin the cooler.AcknowledgementsThe research was supported by the project cofundedby EU ‘Scientific capacity building in fruitgrowing,forestry and information technologysectors, providing research on environmentallyfriendly growing strategies, product development andintroduction aided by computer technologies’ No.2009/0228/1DP/1.1.1.2.0/09/APIA/VIAA/035.References1.
