Effects of 1-MCP on Quality and Storability of Cherry Tomato (Solanum lycopersicum L.)

초록

Cherry tomato is a perishable fruit due to its high rate of ethylene production and respiration during ripening. 1-Methylcyclopropene (1-MCP) is known to control ripening and reduce decay of fruit by inhibiting ethylene action. In the present study, the influence of 1-MCP application on quality and storability of 'Unicorn' cherry tomato was observed. Fruit at pink and red maturity stages were put in the commercial plastic containers and sealed with 40 inn low density polyethylene (LDPE) film, treated with 1-MCP (0 mu L L-1 (control), 0.035 mu L L-1 and 0.1 mu L L-1), and stored at 10 degrees C in 85 +/- 5% relative humidity (RH). The results indicated that application of 1-MCP at 0.1 mu L L-1 significantly affected firmness, cell wall thickness, water soluble pectin, weight loss, surface color, lycopene content and physiological parameters in both pink and red maturity stages compared to 0.035 mu L L-1 and control. 1-MCP treatment at 0.1 mu L L-1 kept the fruits firmer than 0.035 mu L L-1 and the control throughout the storage period for both maturity stages. Cell wall degradation in the control treatment was higher compared to the 0.1 mu L L-1 1-MCP treated fruits in both maturity stages throughout the storage period. Results of this study revealed the effectiveness of application of 0.1 mu L L-1 on quality and shelf life of cherry tomato.
