Wpływ skracania systemów korzeniowych dwuletnich sadzonek świerka pospolitego (Picea abies L. Karst.) na ich wzrost po posadzeniu

The paper presents investigation on influence of root shortening on growth of 2−years−old Norway spruce seedlings after their development in the nursery. Measurements of basic morphological features reveal that strong length reduction increases regeneration of spruce root system. Together with that, slight decrease in height and diameter increment of the main shoot can be observed. Shortening of spruce roots improves significantly the balance between above− and belowground parts of the seedlings as well.
