Opis (eng)

Air-layering is a method of autovegetative propagation, by which the connection between the mother plant and the parts which have to be separated, will be discontinued only after successful rooting. The applied technics consisted in the following: On 10-15-year old plants, on the shoots of 8-15 mm of diameter, peeling of the bark was made in the form of a ring, 1,5-2 cm wide. Lower part of the peeled part was vraped wiih an aluminium band, 8-10 mm wide, which was well tightened with a plastified copper wire, in order to prevent transportation of the assimilatives from the treated branch into the stem. After spreading a stimulator on the remained peeled part of the branch, a layer of humid moss, covering 7-8 cm above and below the wound, was placed on it, and then the whole treated part of the branch was enveloped in a folio of perforated aluminium. As rooting stimulators were used: β - indolil-acetic acid in concentrations of 0,5 and 1,0%, β -indolil-buteric acid in concentrations of 0,5, 1,0 and 2,0%, as well as α - naphtil-acetic acid in concentrations of 0,1 and 0,2% (all dilutions were in talc). The results were extremely good. Depending on the kind of applied stimulator and on the taken dose, the success of rooting was between 65 and 100%, i.e. 88% on average.
