English Abstract

The study was carried out at Darien Private Nursery , Duhok governorate, during early March , 2016 up to the end of July , 2017 , to study Effect of IAA ( 0 , 10 , 20 mg.L-1 ), GA3 (0 , 50 , 100 mg.L-1 ) and Glycyrrhiza glabra L.

extract ( 0 , 1.5 , 3 g.L-1 ) , which all sprayed 2 and 4 times on growth of Pinus brutia Ten , seedlings .

The following traits were measured Shoot fresh and dry weight (g), Dry / Fresh weight ratio, Root fresh and Dry weight (g) , Shoot dry weight / Root dry weight ratio .

The results can be summarized below All studied Characteristics were increased significantly with IAA at the concentration 20 mg.L-1).

Similarly all the studied characteristics were increased significantly by GA3 at (100 mg.L-1) concentration.

Similar trend was resulted with Glycyrrhiza glabra extract at (3g.L-1) as all studied characteristics were increased significantly.

Regarding spraying repetition, it was found that 4 times spraying, enhanced significantly all studied characteristics.

The interaction, of IAA at (20 mg.L-1 ) with GA3 at ( 100 mg.L-1 ) concentration , influenced significantly most of the studied characteristics.

The interaction of IAA (20 mg.L-1 ) with Glycyrrhiza glabra extract ( 3 g.L-1) concentration enhanced significantly all studied characteristics , and the interaction of IAA ( 20 mg.L-1 ) with spraying 4times.

Also , the interaction of GA3 ( 100 mg.L-1 ) with Glycyrrhiza glabra extract ( 3 g.L-1 ) increased significantly most the studied characteristics.

the other hand , most of the studied characteristics were significantly increased by the interaction of GA3 ( 100 mg.L-1 ) at 4 spraying times.

The interaction of Glycyrrhiza glabra extract ( 3 g.L-1 ) with 4 spraying times , affected significantly all measured treats.

Moreover, the most of studied characteristics were increased significantly by the interaction of IAA ( 20 mg.L-1 ) , GA3 ( 100 mg.L-1 ) with 4 spraying times .

The interaction of IAA ( 20 mg.L-1 ) , Glycyrrhiza glabra extract ( 3 g.L-1 ) with 4 spraying times , affected all measured traits .

Concerning the third order interaction of IAA ( 20 mg.L-1 ) , GA3 ( 100 mg.L-1 ) , Glycyrrhiza glabra extract ( 3 g.L-1 ) with 4 spraying times , enhanced significantly most studied traits.
