Abstract


Anatomical features of vertically growing apical shoots of Pinus sylvestris L. and Picea excelsa Link, trees treated with 0.3% morphactin IT 3456 in lanolin paste were analyzed with light and scanning electron microscopes. These studies indicated that the wood formed above and at the area of treatment was morphologically similar to compression wood. Reasons for production of compression wood after treatment with morphactin in vertically growing shoots are discussed.
