Istraživana je mogućnost pospješivanja razvoja lateralnih izbojaka u rasadniku na sadnicama jabuke sorti Jonagold i Golden Delicious. U rasadniku su sadnice, kada su postigle visinu oko 75 cm, podvrgnute sljedećim zahvatima: uklanjanje vršnih nerazvi-jenih listića, uklanjanje vršnih nerazvijenih listića u kombinaciji s tretiranjem s 0,25% Paturylom 10 WSC, tretiranje s 0,25% Paturylom 10 WSC (2 puta u razmaku od 24 dana), tretiranje s 20% Promalinom (GA4+7) dva puta u razmaku od 9 dana. Uklanjanje nerazvijenih listića povoljno je utjecalo na kut grananja, ali nije stimuliralo razgranjavanje sadnica. Tretiranje Paturylom negativno je utjecalo na visinu sadnica, ali je broj lateralnih izbojaka bio veći uz povoljan kut grananja. Uklanjanje nerazvijenih listića u kombinaciji s tretiranjem s Paturylom najpovoljnije se odrazilo na razgranjavanje sadnica. Promalin je povoljno utjecao na razgranjavanje, ali je kut grananja bio nepovoljniji nego u ostalim tretmanima.The ability of various treatments to induce sylleptic shoot development in nursery trees of the apple ‘Jonagold’ and ‘Golden Delicious’ on rootstock M.9 was investigated. The leader management techniques were: removal of sub-terminal leaves, removal of sub-terminal leaves with application of 0.25% Paturyl 10 WSC, and treatment with 0.25% Paturyl 10 WSC (two times at 24 days interval); application of 20% Promalin (GA4+7) two times in 9 days interval; and control, starting when scion length was 75 cm. Removal of sub-terminal leaves increased total branch length, but did not stimulate the lateral branching. Treatments with Paturyl resulted in the lower tree height, in the higher number of branches, and in the greater branch length. Removal of sub-terminal leaves in combination with Paturyl increased the lateral shoot number more than the treatment with only Paturyl. Promalin increased branching, but had little influence on the total branch length. In addition, Promalin decreased branch crotch angles
