Effect of Media and Cutting Diameter on Primary Rooting and Biomass in Acer monspessulanum sub. turcomanicum Seedlings

Acer monspessulanum is one of the important species of the genus Maple that is in danger of extinction due to lack of natural regeneration and the problems caused by drought, pests and diseases. Its propagation by seed is difficult because of the empty seeds, attack insects and seed dormancy (physiological and morphological), so providing the possibility of reproduction through cuttings is very important. The effect of different media (sand, soil greenhouse–30% Litter–20% organic fertilizer –50% loam soil- and sawdust) and cutting diameter (2-6 mm and 6-12 mm) was investigated on rooting percentage, root and stem biomasses. The highest percentage of rooting cuttings (20.83%) obtained in soil of greenhouse with cutting diameter of 6-12 mm and the lowest percentage of rooting cuttings (4.11%) obtained in sawdust in cutting diameter of 2-6 mm. So using of greenhouse soil with 6-12 mm stem cuttings is recommended to propagate through this method.
