| Abstract (english) | The analysis included 15 randomly selected Pedunculate oak seedlings from multicontainers Lieco V-395 at the age of 1+0 and 2+0. The treatments and preparation of the filling substrate of the containers, as well as the type, amount and timing of fertilizer addition were uniformly performed on the automatic filling and seedling line (Urbinati). The following parameters were analyzed on the seedlings and substrate: height, root collar diameter, slenderness coefficient, seedling biomass, root morphological characteristics, substrate pH, and nutrient content (P, K, Ca, Mg, Fe, Mn, Cu, and Zn). The average height of seedlings 1+0 was 24.2 cm, root collar was 7.40 mm, and the slenderness coefficient was 3.37. The average height of seedlings 2+0 was 20.0 cm, root collar was 7.23 mm, and the slenderness coefficient was 2.82. A statistically significant difference was found between the seedling heights of 1+0 and 2+0. The average biomass of seedlings 1+0 was 2.28 g, roots 5.90 g, and stem/root ratio 0.40. The average stem biomass of seedlings 2+0 was 1.93 g, roots 6.00 g, and stem/root biomass ratio 0.32. A statistically significant difference was found between seedlings 1+0 and 2+0 in the following root variables: average diameter, volume, and number of tips. There is a significant difference in the content of P, K, Mg, Mn and Cu in the substrate, which may also indicate inhomogeneous filling that should be further controlled to improve seedling quality. Due to the limited volume, Lieco V-395 containers are not recommended for growing seedlings 2+0. |
