| Popis: | Pruning is an important management practice for regulating tree structure and physiology, and the timing of pruning can enhance forage production during dry periods of the year. Experimental pruning was performed on Guazuma ulmifolia trees to explain the morphological and physiological changes that occur when they are subjected to programmed defoliation to promote regrowth during the dry season. Three prunings (P-1, P-2 and P-3) were conducted from August to October (rainy season), and four foliage harvesting dates (H-a, H-b, H-c and H-d) occurred from February to April (dry season) over 2 years of evaluation. The trees developed similar numbers of branches from pruning and harvesting (P > 0.05). Differing predefined pruning height resulted in greater tree height in P-3. Trees in P-1 developed shorter (P |
