摘要:

Growth regulators, pesticides, herbicides and macroelements applied to tree trunks are often translocated to the foliage. The feasibility of using bark dressings for supplying micronutrients to deficient trees was investigated using new laboratory screening methods and a field trial. Zinc was chosen as a model compound since soil and foliar applications of zinc to apple trees have not proven entirely satisfactory.
