چکیده
Eruca sa t i v a is a very important crop of Madeterranean region, and highly used as salad 3 in European countries . Sodium azide (NaN ) is a chemic a l mutagen, and widely used in crops to 3 improve their yield and quality traits . W e s tudied the effect of various concentrations of NaN ranged (1mM , 2mM , 3 mM, 4 mM and 5 mM) on germination and seedling growth of Eruca at various time 3 intervals . The seeds treated at 5 mM of NaN , the percent germination profoundly affe c t e d o n d a ys 9 and 12 following its application for 120 min and 180 min of time intervals . The h ig h e s t and lowest % germin a t io n was found for 30 min and 180 min of time intervals , whils t seeds were treated at same 3 3 concentration of NaN . The radicle and coleoptile length were decreased as the concentration of NaN increased, and highly affected at concentratio n s 3 mM, 4 mM and 5 mM respectively. More variation was found on radicle length than that of coleoptile leng t h a t s a me c o n centrations and at same time intervals .
