AbstractRYBÁRIK Adam: Effect of selected unconvencional outplanting technologies on European beech and Norway spruce plantation development, after the first growing season. [Bachelor´s thesis] Supervisor – doc. Ing. Ivan Repáč PhD., Technical university in Zvolen, Faculty of forestry, Department of Silviculture. 2019, 51 s.Containerized stock type, application of hydrogels and fertilizers as well as plantation establishment in different planting time represent unconvencional technologies with potential to improve effectiveness of restoration of forests in conditions of disturbed and degraded sites (windthrow areas and extensive clearings). This bachelor's thesis study effect of soil additive application Agrisorb and Silvamix, on survival, level of damage, growth and chlorophyll fluorescence of bareroot and containerized Norway spruce (Picea abies [L.] Karst.) and European beech (Fagus sylvatica [L.]) seedlings, planted in spring and autumn planting time in conditions of windthrow area in Strážovské vrchy Mts., one year after planting. Average survival of seedlings in studied treatments was following: autumn planted seedlings 73 %, spring planted seedlings 81 %, spring planted seedlings treated by hydrogel Agrisorb 78 %, spring planted seedlings treated by slow-release fertilizer Silvamix 84 %, regardless of stock type and tree species. Seedlings were damaged particularly by ungulates (deer). European beech bareroot seedlings planted in spring planting time were tallest, with average stem height 41,78 cm, after the first year after planting. European beech seedlings tended to produce lower leading sprout (5,3 cm) than Norway spruce (8,8 cm). Chlorophyll fluorescence measurement carried out in the end of august, detected no signifficant differences between selected treatments for each of the tree species and stock type combination. Suboptimal values of selected chlorophyl fluorescence parameters (Fm, Fv/Fm) were recorded in all assessed treatments regardless of tree species and stock type. Improved vitality status of short roots as well as higher dry mass of roots of hydrogel treated Norway spruce bareroot seedlings compared to Norway spruce bareroot seedlings in other treatments suggests possitive effect of hydrogel application for this tree species and stock type combination.
