Sažetak
Kerria japonica (L.) DC is a deciduous shrub that is often used in green areas in horticulture and landscape architecture due to its decorative, yellow-colored, multilayered flowers, as well as its high tolerance to drought, low temperatures, and the dust-holding capacity of its leaves. Given the growing demand for this species and the difficulty of generative propagation by seeds, it is necessary to optimise vegetative propagation protocols. This research aimed to examine the influence of phytohormones on the rooting of two types of softwood cuttings (apical and lateral stem cuttings) of Kerria japonica in a greenhouse with a misting system. Cuttings were rooted in 3 treatments: INCIT 8 (commercial phytohormone based on α-Naphthalene Acetic Acid (NAA) in the concentration of 0.8%) and IBA (Indole-3-Butyric Acid in the concentration of 0.6%), as well as a control treatment without hormones. After 30 days of the experiment, the height of the plant, the number of newly formed leaves, the length and the number of roots, the percentage of survival, and rooting were analysed. Apical cuttings consistently exhibited greater plant height, longer roots, and a higher number of roots compared to lateral cuttings, highlighting the importance of cutting position in vegetative propagation. Both auxin treatments (NAA and IBA) resulted in 100% rooting, whereas the control treatment achieved 80%. The results demonstrate that auxin application significantly enhances the rooting quality and growth of Kerria japonica softwood cuttings. These results demonstrate that phytohormone application significantly enhances the rooting and growth of Kerria japonica softwood cuttings. Apical cuttings are preferable for efficient vegetative propagation, but lateral cuttings could be used if needed, providing a basis for the establishment of routine propagation protocols for this species.
