The healing potential of COW dressings containing auxins and other metabolites was studied with various fruit tree species in the orchard and nursery. Indol butyric acid (IBA) was found to induce healing in all deciduous fruit tree species tested. The rate of induced healing is quite fast, and there was good healing after four weeks in most cases. The addition of various metabolites acting as co-factors in callus growth reduced the healing rate induced by IBA or IAA. The effect on lateral and terminal wounds was fairly uniform. COW consistency had no affect on healing as long as it did not contain less than 30% wax. Generally, a chalk, oil and wax dressing, in a ratio of 1 : 1 : 1, containing 2% ZnO and 0.4% IBA, was found suitable as uniform dressing for pruning wounds of deciduous fruit trees in Israel both in orchard and nursery.
