Postavení a výchova třešně ptačí v porostu ve stavu převodu na les střední (ŠLP Křtiny - polesí Vranov)

Wild cherry is a promising tree for our forest management for ecological and economical reasons. In order to achieve a higher economic valuation of cherry wood, a special silvicultural measure must be carried out - artificial pruning. The pruning means removing the lower large branches and thus obtaining long, more quality boles without knots. The pruning of cherries took place in two differently old stands at the Training Forest Enterprise Křtiny. In stand A young wild cherry trees were pruned in three different ways: leaving only this year's increment (S), leaving the last whorl (P) and control, i.e. no pruning (K). In stand B several target trees, that were pruned, were selected and several control cherries without pruning for comparison of increments. The results show that pruning does not influence height growth, but the diameter growth has decreased with increasing intensity of pruning. The same decrease is observed for basal area increment. The data suggest that pruning should be done moderately at a younger stage of cherry development, when the removed branches are not too large
