English Abstract

The possibility of the effect of oryzalin morphological changes inducing was studied for Black poplar (Populus nigra L.) which micropropagated from stem cutting by exposure to different oryzalin concentrations 1, 5, 10, 20 mg / l and different exposure periods (0.0, 2, 4, 6, 8 days) in MS ( Murashige & Skoog ) medium supplemented with 1mg/l BA and 0.3 mg/l IBA.

After 4 weeks of exposure results showed the significant superiority of 1 mg/l oryzalin treatment for stem cutting survival percentage transplant .

After 16 weeks of acclimatization and field growing the results showed the significant superiority for treatment of exposure with 1 mg/l oryzalin for stem length 31.59 cm , stem diameter 2.89 mm , leaves number 15.19 , vegetative system wet weight 9.30 gm and vegetative system dry weight 2.92 gm , this in comparison with 5 and 10 mg/l oryzaline treatments, and this is in combined with fnally the interaction effects of oryzalin for the treatment of 1 mg/l oryzalin for 8 days
