The effect of Kelpak® biostimulator, Wuxal® Ascofol and Pentakeep®-V leaf fertilizers were tested on Prunus mahaleb L. ‘Bogdány’ stockplants. Shoot production and characteristics, rooting and quality of their cuttings were evaluated. Biostimulator and fertilizers were sprayed four times on leaves before cuttings were taken. The number and fresh masses of the shoots, cutting weights, leaf chlorophyll indexes (SPAD) and indole3-acetic-acid (IAA) levels in shoot tip were measured on stockplants. Rooting rates, IAA--levels in the rooting zone of cuttings, fresh and dry masses of rooted cuttings, both weights of the root and shoot were measured. Based on these results Kelpak® pretreatment could be considered as the most effective in improving the productivity of Prunus mahaleb L. stockplants, leaf chlorophyll indexes and IAA-level in shoot tip of stockplant and in cutting base. The stockplant pretreatment by Kelpak® increased both the single shoot mass and consequently the fresh mass of prepared cuttings. While these pretreatments alone did not affect the rooting rate, the pretreatment of shoots by Kelpak® and Pentakeep®-V increased the dry mass production of cuttings during rooting. Kelpak® pretreatment affected the root dry mass positively, while Pentakeep®-V increased the shoot dry mass of rooted cuttings.

In order to improve vegetative propagation of a difficult to root Cotinus coggygria the stock plants were subjected to: etiolation, shading and spraying with IBA, combined with the application of two commercially available rooting powders. The IBA treatment was more suitable for rooting of C. coggygria cuttings than the NAA application and it enhanced rhizot genesis regardless of the form of auxin application (foliar application to a stock plant or a rooting powder used directly on cuttings) and the amount of light provided to stock plants. Etiolation did not improve rhizogenesis in stem cuttings, however, reduction of light intensity by 50 % and 96 % of the ambient prior to harvest of cuttings affected rooting positively. Positive effects of shading can be ascribed to changes in shoot anatomy, i.e. a weaker sclerenchyma development. Synergistic effect of shading and Miar auxin application can result from the increase in leaf blade area and/or thinner lower epiderm. Em hanced rooting in cuttings from shoots grown out under reduced light intensity was accompanied by decrease in the contents of total soluble sugars, soluble proteins and free ABA and by increase in total chlorophyll, free amino acids, polyphenolic acids and free IAA contents.
