ReTainTM maintains ‘pink Lady’ fruit quality during long term storage.
‘Pink lady
’ apples were harvested from two growing regions (
South Australia and
Victoria) and at two harvest maturities (early and late).Fruit were treated with aminoethoxyvinylglycine (AVG, ReTain
TM) at two different times in the orchard (7 and 21 days before harvest).Fruit were harvested according to maturity and stored at 0
°C in controlled atmosphere storage (2% O
2 and 1%CO2) or regular air storage.Fruit quality (internal ethylene concentration, firmness, background colour, starch, soluble solids content etc) were assessed at two monthly periods for up 10 months storage.Fruit were subject to a two week shelf life at 20
°C after six months storage, where aroma production was also measured using SPME/GC. All air stored fruit were removed at six months storage.The ReTain
Tm treatment significantly reduced ethylene production across all treatment and storage regimes, compared to the untreated control.Ethylene production was also lower in the ReTain
TM treatments during the 14 days shelf life at 20
°C after six months storage.Flesh firmness (measured by penetrometer) was generally higher in the fruit stored in CA and in the ReTain
TM treated fruit.This effect was maintained during the entire storage period.The interactions between harvest maturity, growing region and timing of the ReTain
TM treatments will be discussed in more detail in the full paper.
