This work is about comparison of bare-rooted and containerized planting stocks on 5 locations with different conditions, which were established for the purpose of this kind of research. Locations consisted of these forest type sets: 4K, 4S, 5K and two areas with a forest type set 3K. There were 200 bare-rooted varieties and 200 containerized varieties of three species planted on these locations in 2016, namely European beech (Fagus sylvatica L.), Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and Norway spruce (Picea abies (L.) Karsten). After the end of the vegetation period in 2017, measurements were made on the mentioned trees. Hundred individual trees from each variant were measured. The following parameters and features were measured: height of the aboveground part in 2017, height of the aboveground part in 2016, length of the growth of branches, thickness of the root neck, width of the crown, length and width of the assimilation apparatus, ripple of the trunk, diversion of the trunk, height of split of multiple trunk, colour of the assimilation apparatus, crown shape, multiple top, losses. The measurements were further statistically evaluated and the results showed that the containerized variant of European beech has better growth at all evaluated locations. Containerized variant of all plants was better on 5K area than on the other areas. Bare-rooted variant of Norway spruce had better growth on forest type sets such as 3K,3K B,4K, and 4S. Bare-rooted variant of Douglas fir had better results on 3K (Svárov) and 4K areas, but containerized variant had better results on 3K (Vanovice) and 4K area
