Fruit weight, firmness, percent soluble solids, titratable acidity, and flesh Ca, Mg, K, P and N content of ‘Swiss Bartlett’ pears were different among several clonal Old Home x Farmingdale (OH x F), clonal Quince and seedling rootstocks. No rootstock was found to be superior but fruit calcium in pears grown on OH x F 230 rootstock was significantly higher than in fruit grown on all the other rootstocks. Fruit calcium and nitrogen contents were higher in the fruit from trees at age 5 to 6 yrs than in fruit from the same trees at age 11-13 yrs. Fruit Mg, K and P showed no trend with tree age.
