تاثير حامضي الاسكوربيك و السالسليك في ازالة سمية كلوريد الكادميوم بدلالة تكوين الجذور .Vigna radiata L.Wilczek العرضية في عقل الماش .

Abstract

The main objectives of this study were to elucidate the influence of ascorbate and salicylate in alleviating oxidative stress induced cadmium toxicity in mung bean Vigna radiata L. Wilczek grown hydroponically during rooting responce. Supplying of AsA simultaneously with cadmium chloride (CdCl2) was detoxified Cd by approximately duplicating the roots number (10.9 root) compared to general control (6 root ) as well as to CdCl2 control (1 root) . Mean -while,the same rooting response was equalled to that developed by the effect of AsA alone 11.5 root . However, supplying of AsA after CdCl2 treatment (post treatment) was detoxified Cd by raising the root number to the level of control whereas ,the pretreatment with AsA didn΄t have the potency in Cd detoxification . SA treatment at any of the previous timing and the treatment with AsA+ SA did not able to detoxify Cd in cuttings which have no synergistic action between AsA and SA in alleviating Cd toxicity.
