Abstract Maturity and storage characteristics of ‘Bartlett’ and ‘d’ Anjou’ fruits from trees planted in 1965 on 8 Pyrus rootstocks were studied in 1977, with all fruits of a cultivar harvested on the same date. Fruits of ‘Bartlett’/Old Home (OH) had high soluble solids, low weight loss, and rapid change of color from green to yellow after 3 months storage, indicating that these fruits were harvested at optimum maturity. Fruits of ‘d’ Anjou’/OH were also high in soluble solids at harvest and after storage for 3 and 4 months and changed color properly after storage. Fruits from ‘Bartlett’/ P. betulaefolia Bunge, changed color slowly and had high weight loss and firmness after storage, indicating immaturity at harvest. Fruit of ‘d’ Anjou’/ P. ussuriensis Maxim, were firmest at harvest but relatively soft after 3 and 4 months of storage. Fruit of ‘d’ Anjou’/ P. betulaefolia were firm after storage with moderate weight loss, low soluble solids, and cork spot. Fruit of ‘d’ Anjou’/ P. betulaefolia and P. ussuriensis were high in cork spot but low in scald. Some of these changes reflect an apparent rootstock influence on fruit maturation.
