The influence of Gerba 4LG on branching of one-year-old apple nursery trees

Abstract

The object of the research was apple varieties Golden Delicious Reinders, Red Velox, Gala Buckeye and Red Jonaprince, grafted on M 9. The grafting method was chip budding. Planting distance was 80x35 cm. Planting of rootstocks was carried out in the spring of 2015. To determine the influence of the variety and of different intervention techniques on the degree of emission of the anticipated shoots were used: 1. Free eyelid growth (control); 2. Topping of apical leaves was combined with two treatments with Gerba 4LG at a dose of 25 ml/liter of water. It was established that the most reasonable garnishing of the crown formation with anticipated shoots at all studied varieties was obtained by topping the apical leaves in the apex area once when the graft reaches 65-70 cm height combined with twice the sprinkling Gerba 4LG at 25 ml/liter of water. The first treatment was done after breaking the apical leaves and the next at 5-7 days.
