Creative Application of 1-Methylcyclopropene

1-Methylcycloproprene (1-MCP) has been extensively researched for postharvest applications on a diversity of crops. In previous studies we have shown that the rate of change in tomato color at all stages of ripening can be retarded with 1-MCP vapor treatment. Based on these responses, we evaluated the efficacy of pre-harvest applications of 1-MCP to concentrate fruit ripening and reduce the number of harvests in greenhouse grown tomatoes. An aqueous solution of 1-MCP was sprayed on ‘Laura’ tomato plants when approximately 5% of the fruits were at turning and a relatively large proportion of the remaining fruits (50-60%) were at mature greenstage. A single spray of 1-MCP at this stage while delaying the ripening of MG and past MG fruits did not seem to affect the growth, development and ripening of immature fruits. The number of harvests was reduced from 6 in control to 1 in 1-MCP-treated plants. Fruit cracking was reduced by 60% with in the treated fruits. The crop cycle seemed to be unaffected by single spray of 1-MCP. The data collectively suggests that preharvest spray of 1-MCP may improve packout and reduce cost of greenhouse-produced tomatoes.
