Abstract
In this paper the results of two nursery experiments dealing with the influence of preparation for foliar application “Hungavit” on the growth and development of common beech and pedunculate oak bare-root seedlings are given. The experiments were set up as randomized blocks with three treatments and three repetitions. A generally positive influence of Hungavit on the development of seedlings was established. With beech, Hungavit had the greatest influence on the potassium, calcium and magnesium concentrations in leaves, biomass of leaves and stems and several important root properties, such as number of root tips.
The highest concentrations of nitrogen in beech leaves were present in B1 treatment (1% Hungavit). In oak leaves concentrations decrease with dose. Normal values in beech were reached only in B1, and in oak in all treatments. Phosphorus concentrations were highest in treatment 1 in both species, and all values correspond to normal range of values (Bergmann 1992 according to Fiedler and Hohne 1985). Potassium, calcium and magnesium concentrations increase with Hungavit dose (Table 2). The influence of Hungavit on height or radial increment of seedlings was not established.
Leaf and stem biomass of beech seedlings was increasing with dose, and for oak it was hihest in H1 treatment. An increase of lenght, surface area, volume and number of root tips with dose was recorded for beech seedlings (Table 5).
With pedunculate oak, the influence of Hungavit is less pronounced: Hungavit application had a positive influence on the potassium, calcium and magnesium concentrations in leaves and biomass of leaves and stems.
