Figure 4. Cumulative yield per tree, per trunk eross-sectional area, and per acre of trees on various rootstocks 

 or of various cultivars in Massachusetts and Maine. In Massachusetts, Mcintosh trees were not part of the main 

 planting but were planted in the guard rows on M.9 EMLA, B.9, or M.26 EMLA. Bars within state that are not 

 followed by the same letter are significantly different at odds of 19: 1 .
