Abstract. ‘Jonagold’ and ‘Szampion’ fruit treated with 1-MCP had higher flesh firmness (by 10-20 N) than control fruit after storage and also after additional 7 days at 20°C. In the first year of study 1-MCP did not influence apple organic acid content as expressed by titratable acidity (TA) in ‘Szampion’ but ‘Jonagold’ fruits following treatment were having higher TA. During next two seasons TA for treated apples was always higher for both cultivars. 1-MCP treated fruit of both cultivars had higher soluble solids content only in the first season. The results indicate that 1-MCP applied at the beginning of storage greatly affects maturity related processes but its efficacy is cultivar’s and year’s dependent.

on selected features of stored fruits

Summary

‘Jonagold’ and ‘Szampion’ apples harvested at optimum maturity for long term storage, were exposed to 0.6 μl·dm-3 of 1-MCP at 3°C for 24 h and than stored in regular air at 0-1°C. Treated and untreated fruits were analysed after 180, and 240 days plus after additional 7 days at 20°C. Fruit treated with 1-MCP had higher flesh firmness (by 10-20 N) than control fruit after storage and also after additional 7 days at 20°C. In the first year of study 1-MCP did not influence apple organic acid content as expressed by titratable acidity (TA) in ‘Szampion’ but ‘Jonagold’ fruits following treatment were having higher TA. During next two seasons TA for treated apples was always higher for both cultivars. 1-MCP treated fruit of both cultivars had also higher soluble solids content in the first season whereas during two other seasons there were no differences.

The results indicate that 1-MCP applied at the beginning of storage greatly affects maturity related processes but its efficacy is cultivar’s and year’s dependent.
