INDUCTION OF LATERAL BRANCHING IN NURSERY TREES

Maciej G±stoł, Władysław Poniedziałek

 

ABSTRACT



One year old nursery trees of Malus domestica Borkh. ‘Boskoop’, ‘Elise’ and ‘Rubin’ on M9 rootstock were headed in nursery or treated with foliar sprays of: Arbolin 36SL, Arbolin Extra and Promalin at 900 ppm or 1800 ppm a.i. The branching effect was correlated with an increase of rate of active ingredients (a.i.). BA+GA3 based mixtures (Arbolin 36SL and Arbolin Extra) were better than BA+GA4+7 mixture (Promalin). No tree injuries after using chemical branching agent were observed. The environmental condition plays a great role in induction of sylleptic shoots formation.

Key words: apple, branching, plant growth regulators..
