The size of ‘Bing’ cherries is negatively related to yield where leaf area is relatively constant. Data from three years with light, moderate, and heavy yields and six pruning treatments of varying severity produced a regression line where y = 9.7 − .0062x with r = −.95 where y = grams per cherry, x = kg per tree. Since leaf area was relatively constant, this relationship demonstrates the effect of L:F ratio on fruit size. Cherry cultivar evaluation can be improved by recognizing this relationship. Even crude estimates of L:F, plotted against fruit size, separated cultivars that produced large fruit with heavy yields from those that did not.
