"Jonagold" and "Sampion" apples harvested at optimum maturity for long term storage, were exposed to 0.6 ml 1-1 of 1-methylcyclopropene at 3?C for 24 h and than stored in regular air at 0-1?C. Treated and untreated fruits were analyzed after 180 and 240 days plus after additional 7 days at 20?C. Fruit treated with 1-MCP had higher flesh year of study 1-MCP did not influence apple organic acid content as expressed by titratable acidity (TA) in "Sampion", but "Jonagold" fruits following treatment were having higher TA. During the second season a reversed relations were observed. 1-MCP treated fruit of both cultivars had also higher soluble solids content in the first season whereas during the second one there were no differences. The results indicate that 1-MCP applied at the beginning of storage greatly affects the maturity related processes but its efficiency depends on cultivar and year
