Comparative effect of scarification and non-scarification of (Pistacia atlantica) seed in different media and environmental conditions.

This study was carried out to determine the effects of mechanical scarification and non-scarification of seeds coat, before sowing seed of Pistacia atlantica, on the side of the hilum opposite the radicle to speed up germination in various media. Seeds sowed in three different mediums; Sandy soil, Compost and Peat moss. The results showed that peat moss had best performance in almost all the parameters stem length 211.17mm, stem diameter 4.23mm, stem wet weight 6.04 mm, stem dry weight 2.59g, root length 484.42mm, root diameter 4.08mm, root wet weight 2.36g and root dry weight 1.08g. Interaction of indoor, Peat moss medium with scarification significantly increased all the studied parameters.
