Inhibition of alpha -farnesene biosynthesis and its oxidation in the peel tissue of "d'Anjou" pears by low-O2/elevated CO2 atmospheres.

Pear fruits, cv. d'Anjou [Beurre d'Anjou], harvested at optimum maturity with flesh firmness of 63 plus or minus 1 N were stored at -1 deg C ( plus or minus 0.5 deg ) in a controlled atmosphere (CA) environment with 1.5-2.0% O2 for 20 days, followed by another 73 days with 0.5% O2. The CO2 concentration in the CA room began at 0.03% and accumulated gradually to 2.7% after 93 days of storage. The low O2 and high CO2 stress inhibited the accumulation of alpha -farnesene and conjugated trienes in the peel tissue of the fruits. This inhibiting effect was persistent but reversible after fruits were placed in air storage at -1 deg . Fruits subjected to this stress showed no symptoms of superficial scald during 9 weeks of holding in air at -1 deg plus 7 days ripening in air at 20 deg . It is suggested that this treatment may be a potential substitute for the current chemical (ethoxyquin) treatment for the control of superficial scald of d'Anjou pears. However, the high CO2 levels induced pithy brown co
