INFLUENCE OF ROOTING POWDER ON PROPAGATION OF SAGE (SALVIA OFFICINALIS L.) AND ROSEMARY (ROSMARINUS OFFICINALIS L.) WITH GREEN CUTTINGS

Vegetative propagation of medicinal and aromatic herbs with green cuttings is mainly used because of seed low germination percentage and duration of such reproduction. The aim of this investigation was to determine the effect of commercial rooting powder Rhizopon I on the sage rooting (Salvia officinalis L.) and rosemary (Rosmarinus officinalis L.) green cutting. The investigation was conducted in the greenhouse of the Faculty of Agriculture, University of Banja Luka during April till July of 2012. The experiment consisted of two variants. Cuttings of sage and rosemary were treated with rooting powder or planted directly into the substrate without being previously treated. Morphological properties such as plant height, number of leaves, root length, fresh weight and dry weight of plants were recorded. The treatment with rooting powder resulted in significantly higher values of all morphological parameters tested. Therefore, it is highly recommendable to use it in transplants production thus ensuring the proper rooting of cuttings for earlier transplanting.
