| Title : | INFLUENCE OF ROOTING STIMULATORS OF CUTTINGS OF SELECTED WILD PEAR GENOTYPES (PYRUS COMMUNIS L.) FROM THE AREA OF POLIMLJE |
| Abstract : | There are many genotypes of the wild pear (Pyrus communis L.) in the Balkan Peninsula. The large genetic variability of the wild pear is due to century-old adaptation of local populations to certain agro-ecological and soil conditions. Vegetative reproduction using cuttings is one way of clonal multiplication of higher plants. On a theoretical level today, researchers are investigating the regulatory role of phytohormones in rhizogenesis. On a practical level, they are making efforts to identify optimal conditions for the rooting of cuttings and investigating the possibility of using cuttings in a greater number of different plant species, particularly those in which rhizogenesis hardly occurs. Vegetative rooting with known methods can successfully help the production of the rootstocks of the wild pear (P. communis L.). The quality of the root system of 30 genotypes was conditioned with Indole Butyric Acid (IBA) stimulators of different concentrations. With an increase in the IBA concentration from 1,000 to 3,000 ppm, the presence of fibres in the wild pear cuttings increased. The introduction of the genotypes BP 06, BP 07, BP 12, BP 20, BP 40 and BP 41 into nursery production, all of which showed a satisfactory ability to form adventive roots, would eliminate the high variability in generative rootstocks in nursery gardens, in addition to the incompatibility with many noble varieties. |
