ABSTRACT: The objective of study was to study the most appropriate concentrations of hormonal stimulants for rooting grafts and their effects on addition of rooting. The trial was carried out in sampling yards of Pezė areas, Tirana District, in medium alluvial soils, rich to nutritious matters. The experiment was designed in four variants. Control group were represented by V1 and group of experiment was represented by V2, V3, V4 . The grafts, after cleaning their bottom parts, were inserted in solutions prepared according to the rate of concentrations and they were immediately planted. During the treatment, the temperature of environment was 17to180C. The trial was carried out for cultivars ”Shesh i Zi” with rootstocks Koober 5bb. Grafts callused and treated with heteroauxine, were maintained in shady places until planting. Hormonal stimulant, acetic B indolil acid was dissolved in alcohol (5-10 mg acetic B indolil acid was dissolved in 0.5 liter alcohol). This solution was maintained in glass container in dark and cool environment. Before using the solution was diluted with water in glass container according to certain concentrations. Results: rootstocks “Rupestris dy lot x Sheshi zi” and “41 B x Sheshi i zi, treated with acetic B indolil acid of 500 and 1000 ppm concentration had higher percentage of increasing (54 and 56 % ), compared to V1 (without stimulant), whereas as for V2 (250 ppm concentration), the increase of production of first class saplings for grafts “Rupestris dy lot x Sheshi i zi” is negligible (25-25.6%). Negligible results were also obtained from the callused grafts “41 B x Sheshi i zi”. The influence in rooting was lower than in 500 and 1000 ppm concentration (13.3 to 15.3%). Grafts “ Kober x Shesh i zi” callused and treated with acetic B indol acid of 250 ppm concentration had a increase almost equal to 500 ppm concentration. But also in this rootstocks, increase of production was higher than 1000 ppm concentration. Conclusion: Use of hormonal stimulant acetic indolil acid improves quantitative indicators of grape saplings callused and rooted.
