1-MCP treatment may contribute to extend storability of cherry tomatoes, but mainly for fruits harvested at earlier stage of maturity

1 - methylcyclopropene (1-MCP), as an ethylene action inhibitor, is a new tool to improve storability of some vegetables. The aim of the study was to determine the effect of 1-MCP treatment on changes of chemical composition of 'Pareso F1' and 'Dasher F1' ?cherry? tomatoes (Solanum lycopersicum L. var. cerasiforme) during storage. The experiment was conducted in 2011 and 2012. Plants were grown in coconut fibre slabs and fruits were harvested in September at pink and light - red ripening stages (3rd and 5th stage, USDA standard chart),

1 - methylcyclopropene (1-MCP), as an ethylene action inhibitor, is a new tool to improve storability of some vegetables. The aim of the study was to determine the effect of 1-MCP treatment on changes of chemical composition of 'Pareso F1' and 'Dasher F1' ?cherry? tomatoes (Solanum lycopersicum L. var. cerasiforme) during storage. The experiment was conducted in 2011 and 2012. Plants were grown in coconut fibre slabs and fruits were harvested in September at pink and light - red ripening stages (3rd and 5th stage, USDA standard chart), treated with 1-MCP (1 ppm for 12 hours at 18 ?C) and stored for two, three and four weeks at 12 ?C. Before and after storage chemical analyses were carried out. There were determined: dry matter, total sugars content, soluble solids (Brix), pH of juice, titratable acidity and carotenoids content by HPLC. Titratable acidity in fruits of ?Pareso F1? harvested in 3rd stage of maturity was 6.82 (treated) and 5.30 (untreated) after two weeks, 6.75 (treated) and 5.30 (untreated) after four weeks, respectively. Fruits of the same cultivar, harvested in 5th stage of maturity had titratable acidity 5.86 (treated) and 5.09 (untreated) after two weeks, 5.05 (treated) and 4.16 (untreated) after four weeks. Total sugars content in fruits of ?Pareso F1?, harvested in 3rd stage of maturity was 4.04% (treated) and 4.0% 6 (untreated) after two weeks, 3.77% (treated) and 3.91% (untreated) after four weeks. Fruits of this cultivar harvested in 5th stage of maturity showed sugars content 4.46% (treated) and 4.51% (untreated) after two weeks, 4.45% (treated and untreated) after four weeks. Similar trends were observed for fruits of 'Dasher F1'. It was found that 1-MCP treatment is effective in delaying ripening of the fruits and may contribute to extend storability, but mainly for fruits harvested at earlier stage of maturity. The fruits harvested at 3rd stage can be stored longer than fruits harvested at 5th stage. ?
