Studies realized in 2008 and 2009 proved that Neo Arbolin Extra (10 g GA4+7 and 50 g BA in 1 l of solution) and Neo Arbolin (18 g GA4+7 and 18 g BA in 1 l of solution) applied separately or with Algamino Plant (18% extract from seaweeds and 10% of potassium salt of amino acids) stimulated the development of axillary buds on apple maiden trees of ‘Ligol’, ‘Golden Delicious’ and ‘Mutsu’ cultivars grafted on M.9 rootstock, thus enhancing the number of feathers longer than 10 cm. Preparations were applied twice, from the middle of June to July 9. Results differed between years, which may be related to different weather courses during the growing seasons. Neo Arbolin Extra at a concentration 30 ml·l−1 with adjuvant addition (Adpros 5 ml·l−1) gave the best results in branching of maiden trees of three examined cultivars. Trees treated with those preparations twice produced more than 10 feathers (> 10 cm) in the year highly favoring maiden tree growth and more than 6 feathers in the less favorable year. Algamino Plant did not influence apple tree branching.
