THE RESPONSE OF NAJDARED APPLE CULTIVAR TO BRANCHING IN THE TREE NURSERY ACCORDING TO THE APPLIED TECHNIQUES

Rezumat

The experiment was carried out in the years 2021 - 2022, in a commercial nursery of the company SRL "Vindex Agro", where Najdared trees grafted on the M9 T337 rootstock served as biological material. Planting of rootstocks was carried out in the spring of 2021. The grafting method was Chip budding and planting distance was 0,8x0,35 m. In order to intensify the formation of the anticipated shoots in the area of the crown formation, various technological processes were used: V1. Free eyelid growth (control); V 2. Progerbalin LG, 25 ml; V 3. Progerbalin LG, 25 + 25 ml; V 4. Progerbalin LG, 25 ml + topping of apical leaves; V 5. Progerbalin LG, 25 + 25 ml + topping of apical leaves; V 6. Gerba 4 LG, 25 ml; V 7. Gerba 4 LG, 25 + 25 ml; V 8. Gerba 4 LG, 25 ml + topping of apical leaves; V 9. Gerba 4 LG, 25 + 25 ml + topping of apical leaves. It has been established that the most reasonable garnishing of the crown formation with anticipated shoots at Najdared cultivar was obtained by topping the apex area once when the graft reaches 65-70 cm height combined with twice sprays with Progerbalin LG and Gerba 4 LG growth regulators. The first treatment was done after topping the apical leaves and the next at 5-7 days late.
