Agar Journal of Animal and Plant Sciences JAPS 20122012/08/01 22 4 1086-1091 1018-7081 NA <p>&nbsp;The effects of 1-methylcyclopropene (1-MCP) on postharvest quality in four tomato cultivars (&lsquo;601&rsquo;, &lsquo;602&rsquo;, &lsquo;603&rsquo; and &lsquo;Target&rsquo;) were determined during storage. Tomatoes were harvested at pink stages and divided into two lots per each cultivar. One of the lots was exposed to 1000nl l-1 1-MCP doses for 24 h at 20&deg;C while untreated fruits were considered as control. Thereafter, fruits were stored at 10&deg;C and 90% RH for 21 days. During storage weight loss, elasticity, skin color, soluble solid content (SSC), titratable acidity (TA), ripening index (SSC/TA), lycopene and ascorbic acid were measured. The results indicated that in all of the four cultivars, 1-MCP treatment significantly delayed the development of skin color, inhibited the increase of lycopene synthesis and ripening index (SSC/TA) corresponds to tomato fruit ripening. 1-MCP treatment provided better results across all the tested cultivars. Especially, Target cultivar was more responsive to 1-MCP in terms of quality maintenance and storage life extension.</p> Tomato, 1-MCP, postharvest quality, lycopene.
