Polyribosomes from Aging Apple and Cherry Fruit

Abstract
The ripening was investigated of climacteric fruit (Pyrus malus L. cv. Golden Delicious) and of a nonclimacteric fruit (Prunus avium L. cv. Bigarreau Napoleon). Both climacteric fruits exhibit the same preclimacteric sequence of events. Differences exist, however, between the Golden Delicious apple and cv. Passe-Crassane pear in that the protein synthesis capacity of the 2 fruits is not the same during the over-ripening period. A nonclimacteric fruit, the Bigarreau Napoleon cherry, does not show an increase in its protein synthesis capacity during the over-ripening period.
