Abstract

BRACKMANN, Auri; FREITAS, Sérgio Tonetto de; MELLO, Anderson Machado de  and  STEFFENS, Cristiano André. Effect of 1-MCP applied at different times during cold and Ca storage. Rev. Bras. Frutic. [online]. 2003, vol.25, n.1, pp.42-44. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452003000100013.

The objective of this work was to evaluate the effect of 1-MCP applied at different period during the cold storage (CS) and in controlled atmosphere (CA) on the quality of 'Quioto'. Persimmon. The experimental design was completely randomized with four replications of 30 fruits and the tested treatments were: cold storage (CS), cold storage + 1-MCP (1000ppb) in the beginning of the storage, cold storage + 1-MCP (1000ppb) in the end of the storage period; storage in controlled atmosphere (CA) with 1kPa of O2 and 5kPa of CO2 and 1kPa of O2 and 5kPa of CO2 + 1-MCP in the end of the storage, after 2 months of storage at -0.5ºC, plus 5 days at 10ºC and 3 days at 20ºC. In the cooled storage, the 1-MCP, applied as in the beginning of the storage as in the end of the storage, provided greater pulp firmness. For the parameters: total soluble solids, rottenness and darkening of the peel didn't have statistics difference between the treatments. There were no statistics differences between the treatments for total soluble solids, rottenness and darkning of the peel. In conclusion 1-MCP applied in the beginning or end of storage period mantained high firmmness.
