| Abstract | Aims. The aim of the study was to evaluate the rooting success of one- and two-year-old willow cuttings depending on storage methods and cutting length, with consideration of varietal specificity. Methods. The research was carried out using Salix alba L. cuttings of the Hungarian cultivar Corvinus, the Ukrainian cultivar Н1, and the breeding line No. 33-16. Both one- and two-year-old cuttings 10–50 cm long were used. Experimental plots were established using a row planting scheme with 50 cm inter-row spacing and 15–20 cm between plants. Two storage methods were compared: storage in burlap and traditional trench storage (prykopka). Results. Cutting length was identified as the dominant factor determining rooting efficiency. The lowest rooting rates were recorded for short cuttings (10–15 cm): 12–30 % in Corvinus, 25–66 % in Н1, and 25–60 % in line No. 33-16. Increasing the length to 20–25 cm enhanced rooting to 55–78 % (Corvinus), 75–92 % (Н1), and 70–97 % (No. 33-16). The highest rooting percentages were obtained for cuttings 30–35 cm long, which ensured 87–90 % rooting in Corvinus and 94–100 % in Н1 and No. 33-16. In cuttings longer than 40 cm, rooting declined to 54–90 %. Storage method significantly influenced the results: burlap ensured 52–100 % rooting in both age groups, whereas trench storage resulted in 33–98 %. Varietal analysis revealed consistently lower rooting in Corvinus (10–90 %) and the highest in Н1 (69–100 %), regardless of cutting age. Conclusions. Rooting success of willow cuttings is determined by the interaction of cutting length, storage method, and varietal characteristics. The optimal cutting length for planting is 25–35 cm, providing high and stable rooting rates (93–100 %) under both storage methods. Burlap was identified as the most effective storage technique, ensuring maximal rooting in one- and two-year-old cuttings. | ||
