Abstract
The fig is a subtropical fruit species. In the Republic of Macedonia it is grown mainly, in the form of individual plants. Lately there is interest for establishing orchards from this fruit species. The purpose of this research was to determine the influence of some phytohormones on the rooting of hardwood cuttings from fig. The research was conducted with cuttings from 3 domestic populations of figs, “Bela smokva,, “Crna smokva,, and “Petrovka,,. The research was performed on an experimental field, property of the “Faculty of Agricultural Sciences and Food,, in Skopje. In the research, two phytohormones were used, indolebuteryc acid 0,1% and 1-Naphthaleneacetic acid 0,1%. In the end of the vegetation period the following parameters were evaluated: percentage of rooting, diameter and length of the shoots, the total mass of the roots, the length and nubmer of
roots with a diameter above 3mm. On the basis of our research we determined that all of the cuttings had a satisfactory, high, percentage of rooting (86,2%). In the population of “Petrovka,, the treatments did not show any statistical significant differences on the evaluated characteristics, regarding the control treatment. With the cuttings from “Bela smokva,, treated with NAA, statistical significant difference was found in the parameter mass of the roots (12,2g), while regarding the nubmer and length of roots, this treatment, had statistical significant difference just with the control but not with the IBA treatment. With “Crna smokva,, the cuttings treated with IBA had the highest values with statistical significant difference with the number (4,5), the mass (24,3 g) and the length of the roots (179,3 cm).
