Acaciaisabeautifulornamental treewhich is widelyusedin parks and landscape designs.To evaluate the effect of benzyladenine on improving micropropagation of acacia,a randomized complete block design with four levels, 0, 0.5, 1 and 1.5 mgl-1in threereplications. Analysis of varianceindicatedthat the effectof benzyladenineon all measured traits were statistically significantatthe 1% probability level.Mean comparisonshowed thattreatmentwith1 mglbenzyladeninehad the priority to all traits with 3.6 (the maximum nods number), 5.03 cm (the maximum seedling height) , 3.35(the most shoots number) and1.72g (fresh weight).
