This study was conducted to investigate the response of the plum rootstock 'Fortival' to the action of rooting biostimulators, using semi-hardwood cuttings. The experience was located in a solarium equipped with artificial mist installation. The cuttings were treated with different hormones (IBA, NAA and Radistim no.2) and reported to control. The results show that among the biostimulators applied to 'Fortival’ rootstock cuttings, Radistim no. 2 had a superior influence on the development of the root system, compared to both the control and the other used biostimulators, determining the highest rooting percentage, the highest number of roots, the highest average length of roots/cutting, the highest average length of the rooted segment and the largest volume of roots. The F-Test Two-Sample for Variances shows that the variance of the average length of roots/cutting is higher in the case of chemically treated cuttings, regardless of the used biostimulator, which shows the favorable response of 'Fortival’ rootstock to the application of rooting biostimulators used in the study.
