Investigations on the dormancy of Fraxinus excelsior L. buds II. Bud dormancy on shoots in various parts of the tree crown

The course of the particular phases of dormancy of terminal buds from various parts of the tree crown of 12-year-old Fraxinus excelsior trees was investigated. The following treatments breaking dormancy were applied: defoliation, a warm water bath and chilling. Significant differences in the depth of bud dormancy between the main and lateral shoots were noted only in the period of correlated inhibition. No differences could be found either in the course of rest and imposed dormancy or in the process of their receding.
