Cuttings are exposed to several stress factors during rooting. Leaf nutrient sprays may compensate the stress. Six treatments of leaf fertilizers and biostimulators and BA were applied on rooting two cultivars of Prunus mahaleb cuttings. Cuttings were tak-en from untreated stockplants in late May. Each cutting was 20 cm long with three leaves each cut in half. On all cuttings’ base, except for untreated ones, 0.2% IBA were applied by dipping in 50% ethanol solution, than inserted into perlite and rooted under intermit-tent mist. The following leaf spray treatments were applied weekly on rooting cuttings from the first to fourth week: Kelpak® 0.2%, Wuxal® Ascofol 0.2%, Pentakeep®-V 0.05%, Yeald Plus® 0.15%, early BA 0.2%. The later BA treatment started on the 4thweek of rooting. Control was sprayed with tap water. Yeald Plus® and Pentakeep®-V show some improving tendency in rooting rate compared to IBA treated and control (8.9 and 4.0%) on ʽBogdány’ in average of three years. On ʽMagyar’ cuttings, which can be characterized with low rooting potential, foliar sprays of Kelpak®, Wuxal® Ascofol, Pen-takeep®-V and Yeald Plus® significantly increased the rooting rate and the fresh weight increment during the rooting, while Pentakeep®-V and Yeald Plus® significantly increased the total dry weight of rooted cuttings.

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.
