phosphorous the concrentrations were rising with dose especially in HIKO
V–150 containers (Fig. 2). Fertilization had a negative influence on calcium
concentrations, but the deficiency of calcium was not established, regardless
of applied fertilizer dose (Fig. 4).

Both dose and container type influenced significantly the development of
height and root collar diameter of seedlings (Table 3, Figs. 6 and 7). Maximum
height and root collar diameter of seedlings were recorded in HIKO
V–265 containers at the highest fertilizer dose. With HIKO V–150 containers
the highest dose will favor height growth at the expense of root collar diameter.
The type of container was decisive for the development of roots. Fertilizer
dose had a significant influence on lenght and volume of roots, but not on the
number of fine roots or number of root tips. The influence of fertilizer on fine
root development is most pronounced with HIKO V–150 containers, where
seedlings fertilized with the largest dose developed the highest number of active
roots in comparison with other container types.
