 Abstract

The microscopic study is not less important than the Phytochemical study, and it is considered as the first step in the diagnostically determination of the spices studies. Microscopic Sections of Laurus nobilis leaves and fruits were done by using paraffin molds, and a hand Microtome in order to conducting a light microscopical study to determine the histological tissue of this plant parts. Also, light microscopic study was done on the crushed leaves and fruits of Laurus nobilis in order to determine the specific diagnostic elements of this plant parts. The study revealed the existence of microscopic diagnostic elements characteristic of Laurus leaves, such as the oil cells, the pore shape, and the elongated epidermis cells, while the fruits powder are characterized by the stone cells which formed the endocarp..

Results showed that concentration 0.5  of sodium hypochlorite for 10 minutes was the best and gave 28% of germination per cent in average. While in multiplication media, control exceeded in length plant parameter in average 2,04 cm compression with all other treatments, but growth regulators increased the number both of branches and leaves, where MS3 and MS4 media exceeded in average of branches number ( 3.43-3.53 ) and (12.91، 14.64)for leaves number respectively. Higher root formation percent was 75% in MS medium supported with 2 mg\L IBA.
