Abstract
This research includes the effects of preharvest 1-Methylcyclopropene (1-MCP) (Harvista) treatments on fruit drop, fruit quality and harvest maturity of ‘Pink Lady- Cripps Pink’ apple cultivar. The research had materialized in 2016 and 2017. For this purpose, preharvest 1-Methylcyclopropene treatments at doses of 50, 100, 150 and 200 g ha-1 were applied to ‘Cripps pink’ apple cultivar in Çanakkale, Lapseki region, Turkey. Samplings collected from trees at application day and 7, 14, 21 and 28 days after applications respectively. Fruit drop rate, flesh firmness, soluble solids content, starch degradation, titratable acidity, skin color, and ethylene production were evaluated after each sampling date. Furthermore, fruits were kept at 20-22°C temperature and 50-60% relative humidity conditions for 7 and 14 days as shelf life to determine the changes in quality assessments. According to the results, Harvista applications with 150 and 200 g ha-1 doses were found out as the most positive applications because of preventing fruit drop and minimizing the changes of quality parameters. Harvest maturity could be prolonged for 21 days with these application doses.
