Suppression of ripening and induction of asynchronous ripening in tomato and avocado fruits subjected to complete or partial exposure to aqueous solutions of 1-methylcyclopropene

Effect of Postharvest Application of 1-Methycyclopropene on Storage Behavior of Fresh Tomatoes (S olanum lycopersicum L.)

“…The next day, the fruits were dipped in aqueous solutions of 1‐MCP (Choi et al . ) and further storage studies were conducted in the postharvest laboratory of the Department of Fruit Science, Punjab Agricultural University, Ludhiana, Punjab, India.…”

“…The entire procedure of 1‐MCP treatment was followed as per the procedure and care suggested by Choi et al . () and the control fruits were dipped in 10 L distilled water without chemical. After imposing these treatments, fruits were taken in open plastic crates and kept in cold store at 13 ± 2C and RH 85–90% for further storage studies.…”

“…Choi et al . (,) reported that “Soraya” tomato fruits immersed in 625 μg/L of 1‐MCP (AFxRD‐300) for 1 min was comparable in efficacy at suppressing softening and surface color changes to treatment with gaseous 1‐MCP (SmartFresh 0.14%, AgroFresh Inc., Rohm & Haas Company, Philadelphia, PA) at 500 nL/L for 9 h. The present study was conducted to find out the efficacy of 1‐MCP at different concentrations and their effect on storage behavior of fresh tomatoes when stored at 13 ± 2C and R.H of 85–90%.…”

Etileno y retardantes de la maduración en la poscosecha de productos agrícolas. Una revisión

“…El 1-MCP disminuye la producción de etileno (Ma et al, 2009;Cerqueira et al, 2009;Choi et al, 2008;Zhang et al, 2012), debido a que afecta su síntesis autocatalítica al disminuir la expresión de genes que codifican para las enzimas ACS y ACO. Por ejemplo, el 1-MCP disminuye la expresión de los genes ACS1, ACO1 y ACO2 en manzano (Yang et al, 2013), banano (Golding et al, 1999), tomate (Klee y Giovannoni, 2011), durazno y brócoli (Gang et al, 2009).…”

“…El 1-MCP disminuye la pérdida de firmeza en frutos de pera (Villalobos et al, 2011), ciruela (Khan y Singh, 2007), tomate (Choi et al, 2008), guayaba (Cequeira et al, 2009), banano (Lohani et al, 2004, kiwi (Boquete et al, 2004), aguacate (Jeong y Hubert, 2004), fresa (Balogh et al, 2005), entre otros. Lo anterior se debe a que el 1-MCP disminuye la actividad de enzimas que degradan pared celular, como pectin-metilesterasa (PME), poligalacturonasa (PG), endo-β-1,4-glucanasa (EGasa) y pectato liasa (PL) (Lohani et al, 2004;Khan y Singh, 2007), además de expansinas (EXP), β-galactosidasa, α-arabinofuranosidasa y β-xilosidasa (Boquete et al, 2004).…”
