Effect of Chemical Mutagen on Some Biochemical Properties of Stevia rebaudiana Bertoni
Induced mutagenesis causes an increase variation of some products with limited genetic resources. In this study, the antioxidant enzymes activity, biochemical properties and glycoside content of Stevia were assessed by EMS (chemical mutagen) based on two experiments as factorial with completely randomized design with three replications. The results of the first experiment showed that some prope...
متن کاملDiepoxybutane as a Chemical Mutagen in Zea Mays.
IEPOXYBUTANE (DEB) has been used very effectively as an inducer of Dgene mutations in Neurospora (KOLMARK 1953; KOLMARK and GILES 1953; KOLMARK and WESTERGAARD 1953; WESTERGAARD 1957), chromosome deficiencies and rearrangements in Drosophila (BIRD and FAHMY 1953; FAHMY and BIRD 1953; FAHMY and FAHMY 1956), reversions in Escherichia coli (DEMEREC et al. 1954), and chromosome breaks in the Vicia ...
متن کاملBlood Detection by Chemical Methods
Catalytic tests These tests rely on the fact that haem can catalyse the breakdown of hydrogen peroxide. As the H2O2 breaks down, another substance in the reaction mixture is oxidised, producing a colour change. It is important to note that a positive test does not mean that a given stain is blood, let alone that it is human blood, as various enzymes and certain metals can also give positive res...
متن کاملChemical Mutagen Effect on Physiological Properties of Stevia rebaudiana Bertoni under Salt Stress
The present study was performed to evaluate the effects of different concentrations of ethyl methane sulfonate (0, 0.1, 0.2 and 0.5%) on some physiological characteristics of regenerated plants from calli of stevia at 30, 60 and 120 min under various levels of salinity stress (0, 50 and 100 mM of NaCl). This experiment was carried out based on completely randomized two-factorial designs with th...
متن کاملInhibition of dietary mutagen activation by methylxanthines
The investigation of the link between diet and cancer in man has resulted in the identification of a variety of carcinogenic and mutagenic principles in food, particularly cooked meat (Furihata & Matsushima, 1986), the most mutagenic of these compounds being the amino-imidazoaza-arenes:2amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx), 2amino-3,4,8-trimethylimidazo[4,5-f]quinoxaline (DiMeIQx...
