acid or naphthalenacetic acid solutions at concentrations ranging from
10-6 to 10-3 M. The treated fruits were either further
anointed or not with coconut oil or palm kernel oil. Untreated fruits
were used as controls. Treatments with solutions of both types of auxins
at concentrations >=10-4 M strongly accelerated the ripening
of bananas whereas treatments with solutions of these hormones at 10-6
M concentration induced an increase of the shelf-life of bananas. Although
singly treatments with coconut oil or palm kernel oil also had retarding
effects on the ripening, simultaneous treatments with auxins used at concentrations
>=10-4 M and any of the two oils rather accelerated this process
in banana fruits. Treatments with an auxin alone or in combination with
an oil stimulated the decrease in water content in the peel from stage
1 to stage 3 of ripeness. Those treatments that prolonged the shelf-life
of bananas subsequently induced a delay in the decrease in water content
in the peel from stage 3 of ripening upwards. These results indicated
that the role of ethylene in the regulation of ripening process in banana
fruits may be modulated by the endogenous concentration of auxin.]]>Abel, S., M.D. Nguyen, W. Chow and A. Theologis,1995Arabidopsis thaliana.
