<p>The invention relates to a method for producting clones of woody plants. According to the method, first, the mother plants are selected from selected clones in order to produce root cuttings and the mother plants are grown long enough to form a strong root system. After the growing period, the grown mother plants are left in dormancy. The root system of the mother plant is recovered, the thinnest part of the root system is removed, and the roots are cut. The pieces of root, i.e., the root cuttings, are brought to rooting conditions to take root in a suitable growth medium or, optionally, the root cuttings are pre-treated. The root cuttings that have taken root and/or started to grow a shoot are selected, recovered, and grown to become plants. Alternatively, the root cuttings obtained from cutting or pretreating the roots are selected and inserted directly into the selected area of forest cultivation.</p> |
