In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually dna, of an organism and thus increases the frequency of mutations above the natural background level as many mutations can cause cancer, mutagens are therefore also likely to be carcinogens, although not always necessarily sosome chemicals only become mutagenic through cellular processes. Increase in the doses of gamma rays in zea mays (maize), abelmoschus esculentus (okra) and arachis hypogaea (groundnut) (mokobia & higher doses of gamma rays inhibited the seedling stem growth in pinus banksiana (jackpine) (amiro, 1986) physical and chemical mutagens review of literature 11 gamma rays-induced semi-dwarf mutant with.

The aim of this research was to evaluate the effectiveness of irradiation with gamma rays on corn for the control of aflatoxin b1 for this purpose, three treatments were compared: treatment 1, application of gamma radiation, treatment 2, application of antifungal and treatment 3, combination of gamma radiation and application of antifungal.
The purpose of this study was to determine the effect of varying levels of gamma radiation on growth parameters of zea mays l ten seeds for each level of gamma radiation (0 krad, 10 krad, 30 krad and 50 krad) were planted and tested for the number of germinating seeds and plant height, using a meter stick or ruler. Effects of gamma radiation in the growth of zea mays by shaameine effects of gamma radiation in the growth of zea mays search search radiation such as x-rays or gamma radiation is a potent mutagen (hartl 2011) the biological effect of gamma rays is based on the interaction with atoms or. Electromagnetic radiation consists of electric and magnetic moving ridges while the ionising radiation consists of x raies and gamma-rays which are energetic plenty to bring forth reactive ions that react with biological molecules ( al-salhi et al , 2005 ) ionizing radiation, at higher doses, may do both mutant and decease of the cell.
Mutation was induced via a physical agent, radiation 4 levels of radiation—0 kr (control), 10 kr, 30 kr, and 50 kr—were used in seeds to determine the radiation effects on the growth of zea mays using two duplicate set-ups, each, planted with 18 seeds per radiation, the differences in height were observed from january 29 [. Effect of gamma ray irradiation and ethyl methane sulphonate on in vitro mutagenesis of citrullus colocynthis (l) schrad. Zea mays assays of chemical/radiation genotoxicity for the study of environmental mutagens zea mays assays of chemical/radiation genotoxicity for the study of environmental mutagens grant, william f owens, elizabeth t 2006-09-01 00:00:00 from a literature survey, 86 chemicals are tabulated that have been evaluated in 121 assays for their clastogenic effects in zea mays. Data are tabulated on the effects of different mutagens on plant height, leaf length, leaf width, pollen sterility and cytological aberrations in maize stocks mk01 and 19-3-3 the treatments were γ radiation, and γ radiation combined with the synthetic growth regulator crossing, the biostimulator phytostim, an electrical field, exposure to an electromagnetic field of extremely high frequency.
Gamma radiation effects on seed germination and growth, protein content, peroxides and protease activity, lipid per oxidation in desi and kabuli chickpea pak j. The gamma rays have negative effect on the germinations of the seedlings of maize genotypes the increasing of the gamma irradiation decreased the growth of the germination the genotypes treated with the high doses (150-200gy) were germinated but they failed to survive (zea mays)is an important cereal crops throughout world1,2 its ranks. Gamma radiation effects on seed germination 627 22 gamma irradiation irradiation of maize seeds was performed using a 60co (cobalt 60) gamma source (gamma chamber 900) in ambient conditions at the faculty of physics, “babe¸s-bolyai” university.
