Efficiency of Progelbalin LG and Gerba 4LG products on the branching of m9 trees in tree nurseries

Abstract

In order to determine the influence of variety and different intervention techniques on the degree of emission of anticipated shoots the following variants were tested: 1. Free growing (control); 2. Progerbalin LG, 25 ml; 3. Progerbalin LG, 25 + 25 ml; 4. Progerbalin LG, 25 ml + topping of apical leaves; 5. Progerbalin LG, 25 + 25 ml + topping of apical leaves; 6. Gerba 4 LG, 25 ml; 7. Gerba 4 LG, 25 + 25 ml;

8. Gerba 4 LG, 25 ml + topping of apical leaves; 90. Gerba 4 LG, 25 + 25 ml + topping of apical leaves.

Lower values of tree height of Gala Schniga SchniCo Red variety were recorded in the control variant (177 cm) compared to the other variants taken in the study (184-

210 cm). The results obtained demonstrate an influence of the products taken in the study on the given index and there is a general tendency that in the variants where the apex was intervened by different methods the tree height was 4.0-18.6% higher compared to the values recorded in the control variant.
