%X The effect of blue light (400–500 nm) removal on the elongation of Scots  pine (Pinus sylvetris L.) seedlings was investigated in a field  experiment in Northern Finland during two growing seasons. The seedlings  were grown in plexiglass chambers and ambient control plots. The blue  wavelengths were removed from the light spectrum by using chambers made  of orange plexiglass. The results of nearly daily measurements showed  that the elongation of Scots pine seedlings was increased by the removal  of blue light only at high latitudes.
