OBSERVATIONS OF THE GROWTH AND VIGOR OF SPUR AND NON-SPUR-TYPE APPLE TREES |
| Authors: | C.S. Walsh, Anita N. Miller |
| Abstract:
Field comparisons of the growth and vigor of spur and non-spur-type apple trees showed that the commercially-available spur-type trees differ widely in growth and shoot development. Not all spur-type trees exhibit the characteristic degree of compactness seen in spur-type Delicious trees. Differences in internode length, escape of lateral buds from apical dominance, and canopy density were noted among spur-type trees of different cultivars. | |
