Softening and ethylene production of kiwifruit reduced with 1-methylcyclopropene.

Kiwifruit soften rapidly in response to exogenous ethylene and susceptibility increases with advancing fruit maturity. Premature softening at 0 deg C is undesirable and can result in significant economic losses. Strategies are needed to reduce rate of fruit softening during storage. Kiwifruit were exposed to 0, 1, 10 and 100 micro l l-1 1-methylcyclopropene (MCP) for 16 h then maintained at 20 deg C after harvest or at 0 deg C for one month before transfer to 20 deg C. MCP reduced ethylene production and softening in fruit maintained at 20 deg C after harvest, with only minor differences between treatments on fruit from 0 deg C. The MCP effect tended to be concentration dependent. Fruit were exposed to either 10 micro l l-1 MCP immediately after harvest and treated with 10 micro l l-1 ethylene after different times at 20 deg C or 0 deg C, or treated with MCP and ethylene on removal to 20 deg C after different times at 0 deg C. When applied at harvest MCP had little effect on C2H4 induced softening after fruit removal from 0 deg C. However when MCP was applied after fruit removal from 0 deg C and then challenged with C2H4, softening rate was reduced to a level similar to controls and fruit treated with MCP

alone.
