Abstract
This experiment was conducted during the spring growing season 2015 inprivate farm of Babylon to study the impact of spraying salicylic acid ,enraizaland their interaction on some physiochemical propertiesof white oleander(Nerium oleanderL .). Plants were sprayedtwo times in 30 days intervals with three levels of Salicylic acid(SA) (0 ,100 and 200 mg. L-1) and three levels ofenraizal(En) with( 0, 5 and 10ml. L-1). Randomized Complete Block Design( R.C.B.D. ) with three replicates(15 plant for each treatment) was adopted.Means were compared by L.S.D.O.O5.Vegetative growth and chemical indicators significantly increased with the SA200 mg.L-1 and En 10ml.L-1except the for leaf area and carbohydrates, that increased significantly by spraying (En 5), IAA significantly increased when spraying by (SA100).(SA200 + En 10) significantly increased plantheight,leaf number, leaf area ,fresh weight,dry weight ,chlorophyll,carbohydrate and GAat73.98cm,70.65 leave .plant-1, 20.87cm2,67.78gm,29.76gm, 80.65 µgm.gm-1,18.89mg.gm dry weight,37.61 mMrespectively as compared to control treatment. Shootnumber waseincreased by(SA200+ En5) treatment at 15.87shoot.plant-1.IAAwase also increased by(SA100+ En10) treatment.Itwas concluded that Salicylic acid and Enraizalenhance growth and chemical properties of White oleander characters
