    THE REPRODUCTION OF MEDITERRANEAN FORESTRY PLANTS OUT OF THEIR HABITAT. EXAMPLE: THE ATLAS CEDAR

    This paper presents the experimental results of assessments of choosing container, type, substrate, nutrition and controlled mycorrhization on plant growth. The results demonstrate the necessity of using anti-coiling containers with a 400 cm3 minimum volume.

    Substrate plays an important part in root development and seedlings physiology. Height quality seedling are now being grown on a mixture of 50% long fibre peat and 50% composted pine bark. Supplying mineral elements to this substrate proved essential to allow seedling development. These supplies can consist in weekly waterings with a nutrient solution, complementing a fertilizer incorporated in the substrate during its preparation. As regards controlled mycorrhization, the first results show that inoculation success is tightly bound to type of inoculation: only sporal inoculation with Tuber albidum reached the mycorrhized seedlings.
