Short anaerobiosis period prior to cold storage alleviates bitter pit and superficial scald in Granny Smith apples.
BACKGROUND Californian Granny Smith apples are very susceptible to bitter pit (BP) and superficial scald symptoms that develop during cold storage. The main preventive means are diphenylamine dipping and/or gaseous application of the ethylene inhibitor 1-methylcylclopropene (1-MCP), which is effective against superficial scald but not against BP. This study investigated the efficacy of a non-ch...
متن کاملRelationship between production of ethylene and a-farnesene in apples, and how it is influenced by the timing of diphenylamine treatment
The relationship between ethylene and peel a-farnesene concentrations was examined by applying diphenylamine (DPA) and the ethylene analogue, propylene at varying times after harvest to superficial scald (scald) susceptible ‘Granny Smith’ apples (Malus domestica Borkh.) stored at 10°C. Delaying DPA application after harvest had no large effect on ethylene or on peel a-farnesene production. Prop...
متن کاملStripped corn oil emulsion alters ripening, reduces superficial scald, and reduces core flush in ‘Granny Smith’ apples and decay in ‘d’Anjou’ pears
‘Granny Smith’ apples (Malus x domestica Borkh) and ‘Beurre d’Anjou’ pears (Pyrus communis L.) were dipped in a 2.5, 5, or 10% stripped corn oil (a-tocopherol B5 mg kg) emulsions, 2000 mg l diphenylamine (DPA), respectively, at harvest and stored in air at 0°C for 8 months. Untreated fruit served as controls. In oil-treated apples and pears, ethylene and a-farnesene production rates were lower ...
متن کاملSuperficial Scald versus Ethanol Vapours: A Dose Response
Early picked ‘Granny Smith’ apples (Malus domestica Borkh.) were stored under air or CA (controlled atmosphere at 2 kPa O2 and <1 kPa CO2) at 1°C. During the first week of storage, fruit was subjected to ethanol vapours in doses from 0 to 8 g/kg of fruit. Ethanol at 4 g/kg protected fruit against superficial scald in CA storage for at least 5.5 months, plus two weeks in cold air storage, plus a...
متن کاملStudy of the Drying Kinetics of “Granny Smith” Apple in Tray Drier
Th e drying characteristics of “Granny Smith” apples were analysed using a tunnel drier at diff erent temperatures and diff erent pre-treatments. „Granny Smith“ apples were cut into rectangle-shaped samples 20x20x5 mm in size. Th e drying temperatures for non-treated samples varied from 50oC to 80oC at airfl ow velocity of 2.8 m s-1. Prior to drying at 60oC, the samples were pretreated either t...
