Abstract

JOMORI, Maria Luiza Lye; KLUGE, Ricardo Alfredo; JACOMINO, Angelo Pedro  and  TAVARES, Silvio. Cold storage of 'Tahiti' lime: use of 1-methylcyclopropene, gibberellic acid and wax. Rev. Bras. Frutic. [online]. 2003, vol.25, n.3, pp.406-409. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452003000300011.

The storage of 'Tahiti' lime under low temperatures allows the marketing period to be extended, however the loss of the green skin colour prevent such improvement to be achieved. The purpose of this research was to verify the efficiency of 1-methylcyclopropene (1-MCP) associated with the use of gibberellic acid (GA) and wax during the cold storage of 'Tahiti' lime. The treatments used were: T1: fruit without treatment (control); T2: 1-MCP (1,0 ì L. L-1) during 12 h at 20ºC; T3: wax (0,1 mL per fruit); T4: GA (10 mg. L-1); T5: 1-MCP + wax; T6: 1-MCP + GA; T7: wax + GA; T8: 1-MCP + wax + GA; T9: T2 + new application of 1-MCP after 30 days of storage. Fruit were stored during 30 and 60 days at 10ºC and 90% RH. The wax application was sufficient for the maintenance of green skin colour after 30 days of cold storage. 1-MCP maintain the green skin colour up to 30 days of cold storage, while new application of 1-MCP after this period does not present effect for the maintenance of colour. After 60 days of storage the fruit did not become marketable.
