In the present study of Pinus pinea L., further improvement of microshoot rooting was achieved by applying Cool-white light at increased intensity from 60 to 90 μmol m-2 s-1. In contrast, light provided by Gro-lux lamps promoted rooting of the microshoots at the same frequency regardless of its intensity. Majority of microshoots (70.4%) grown under Cool-white lamps at the intensity of 90 μmol m-2 s-1 were also significantly taller when compared with those from other tested treatments.
