NAFEXers: There are a couple of apples that I'd very much like to be able to grow and ripen up here on the Maine Coast/Zone 5, but I'm probably right on the fringe of where they'll ripen properly.


Hello,

I believe there is research going on regarding spray treatments to hasten ripening.

HORMONAL CONTROL OF FRUIT
MATURATION AND RIPENING II. CHANGES
IN ABSCISIC ACID CONTENT IN APPLE
FRUITS TREATED WITH GROWTH
SUBSTANCES
 

Authors: E.S. Hegazi, H. Plich
Abstract:
The influence of growth substances enhancing (CEPA, NAA), or delaying
 (SADH) fruit ripening on ABA content during maturation of apple fruits cv.
 McIntosh was studied. Control fruits attached to the tree contained a low
 amount of ABA during the last two weeks before harvest. Fruits treated
with CEPA 250 ppm alone or combined with NAA 20 ppm or with NAA 20
ppm and SADH 1000 ppm showed a considerable increase of ABA in
comparison to control. The content of ABA in fruits treated by SADH
1000 ppm increased too. The possibility of the relationship of ABA and
ethylene during fruit maturation and ripening is discussed.
