Modification of mutagenic efficiency of sodium azide.

Mutagenic interactions in combined treatments of ethylmethane sulphonate,diethyl sulohate and sodium azide on barley

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Mutagenic Effectiveness and Efficiency of Gamma Rays, Sodium Azide and Their Synergistic Effects in Urd Bean (Vigna mungo L.)

Mutagenic effectiveness and efficiency of gamma rays sodium azide and their combination treatments were studied in the genotype of urdben variety T9. The usefulness of any mutagen in plant breeding depends not only on its effectiveness but also upon its efficiency. Mutagenic effectiveness is a measure of the frequency of mutations induced by unit mutagen dose, whereas mutagenic efficiency is me...

Mutagenic Effect of Sodium Azide on Seed Germination of Eruca sativa (L.)

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 int...

Reaction of Sodium Azide with 1,1'–Dicyclohexenyl–Diepoxides

Nucleophilic ring opening of dl and meso 1,1¢- dicyclohexenyl diepoxides by sodium azide in dioxane and aqueous alcoholic medium give the corresponding azidoalcohols. The obtention of departure diepoxides from diazidoalcohols by the reaction with sodium hydride shows the anti position of OH and N3 groups.
