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 the growth response of Pinus brutia Ten , seedlings sprayed with different concentrations 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 , the experiment was designed as factorial with four factors ( IAA , GA3 , Glycrrhiza glabraL.

, and sprayed thies ) with three replications.The following traits were measured:-Shoot length, Shoot diameter, Length and Diameter of the main root, Leaves minerals content , including .

N, K, Na, %.

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, with the exception of root diameter which were affected significantly by the interaction of IAA(20 mg.L-1 )with GA3 ( 0 mg.L-1 1) 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 .

On the other hand , most of the studied characteristics were significantly increased by the interaction of GA3 ( 100 mg.L-1 ) at 4 spraying times, with the exception of main root diameter which were increased significantly by the interaction of GA3 ( 50 g.L-1 ) with 4 spraying times.

The interaction of Glycyrrhiza glabra extract ( 3 g.L-1 ) with 4 spraying times , affected significantly all measured treats .Regarding the second order interaction, IAA ( 20 mg.L-1 ) , GA3 ( 100 mg.L-1 ) with Glycyrrhia glabra extract ( 3 g.L-1 ) enhanced significantly shoot length, diameter .

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 , but the interaction of GA3 ( 100 mg.L-1 ) , Glycyrrhiza glabra extract ( 3 g.L-1 ) and 4 spraying times influenced significantly most 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.
