Gamma radiation is a form of nuclear radiation produced by certain radioactive elements as they decay in particular, gamma radiation is ionizing radiation, meaning that it is sufficiently energetic to break bonds in genetic material, structural components of cells and other biological molecules. There are numerous forms of radiation, including gamma rays, which can hinder the seed germination, root growth and shoot growth of a plant, and ultraviolet, or uv, radiation from the sun, which helps to feed a plant after it has germinated and reached the surface of the soil. The magnitude of the effects of radiation on water is dependent on the type and energy of the radiation, namely its linear energy transfer a gas-free water subjected to low-let gamma rays yields almost no radiolysis products and sustains an equilibrium with their low concentration. Effects of gamma-radiation on cell nential phase of cell growth, with 2, 10 or 20 gy γ-rays from a effects of γ-ir on du 145 cell growth the effects of γ. This experiment examines effects of x-ray radiation on e angustifolia germination and growth, over a vast range (10-35kv) of energy levels to determine effcts of radiation on seed germination and growth, and the lethal dose for e angustifolia.
Gamma rays can kill living cells, a fact which medicine uses to its advantage, using gamma rays to kill cancerous cells gamma radiation is the most penetrative type of energy currently known can get past even some of the densest materials in use, making them both a great benefit and a hazard. Effect of gamma rays radiation on growth of corn 1975 words | 8 pages rate (%) of corn (zea mays) exposed in different doses of gamma rays radiation. Examples of ionizing radiation are high frequency ultraviolet rays, x-rays and gamma rays ionizing radiation has found applications in fields of research, medicine, energy amongst others however, it must be handled safely and carefully because exposure can cause damage to living tissue, radiation sickness, skin burn and even death.
The effects of gamma radiation are investigated by studying plant germination, growth and development, and biochemical characteristics of maize. A 179 180 stimulation of plant growth by ionizing radiation only a few years after the discovery of x-rays by roentgen in 1895 reports of a stimulating effect on plant growth by x-irradiation began to appear. A gamma ray or gamma radiation (symbol γ or ), is a penetrating electromagnetic radiation arising from the radioactive decay of atomic nucleiit consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy.
The effects of gamma radiation are investigated by studying plant germination, growth and development, and biochemical characteristics of maize maize dry seeds are exposed to a gamma source at doses ranging from 01 to 1 kgy. Gamma rays are a form of ionizing radiation their effect is in some ways similar to chemical oxidants (like hydrogen peroxide), but the damage they produce is more spatially clustered. Depending on the types of exposure, the negative effects of gamma rays vary from skin rashes to cancer high doses of gamma rays can cause death gamma rays are the most powerful forms of radiation because they can penetrate skin, wood, paper and other matter. Gamma rays, belong to ionizing radiation, can be energetically charged particles such as electrons, or high-energy photons the biological effect of gamma rays is based on the interaction with atoms or.
Gamma (γ) -ray irradiation is a conventional technique to produce mutants in plant breeding to investigate the effect of γ rays to produce flower color mutants in the genus torenia (linderniaceae). The study aimed to determine the effect of different amounts of gamma rays radiation on the growth of corn (zea mays) and to observe the damage it has brought in relation to the amount used for the treatment. Abstract the effects of irradiation with low doses (0, 10, 20 and 30 gy) of radioactive cobalt (60 co) γ rays on seed germination, shoot and epicotyl growth of hard wheat (triticum durum desf) were investigated under laboratory and glasshouse conditions.
Seeds were exposed to gamma rays at doses (0, 25, 5, 75, 10, 125,15, 175 and 20 kr) to examine their effects on germination and survival percentage, growth traits and morphological variation. Effect of gamma radiation on growth and metabolic they reported that low doses of gamma rays, less than 1 kgy, could stimulate its growth small changes in the. Exposure to gamma radiation (500 rads), known to cause significant increases in channel catfish growth rate, was found to have a similar effect on tilapia after a 20-week growth period, exposed fish weighed an average of 20% more than controls.
Summary the effects of γ-radiation on growth and morphogenesis ofhaworthia callus in vitro were determined the doses ranged from 100 to 5000 rads survival, growth pattern, growth rate, and differentiation of vegetative buds and roots in both irradiated and nonirradiated callus were compared. The effect of radiation on plant growth and generation of mutant populations was explored the lethal effect of radiation was higher in acutely irradiated m0 populations.
