Impact of gamma rays on the germination

Impact of gamma rays on the germination to find out ld50 dose for the seed and urther investigate the influence on germination and seedling parameters the experimental results revealed that the percentage of germination had decreased after irradiation and the effect become stronger with increase of gamma dose. Germination tests and biometric measurements are routinely used to to evaluate the impact of γ-rays in seeds (chaudhuri, 2002), however additional parameters need to be considered since the dose-dependent response of seeds to γ-rays correlates with the extent of free radical accumulation (macovei and tuteja, 2013. The effect of ionizing radiation, specifically gamma radiation, on the germination, growth, and survival of zea mays was studied by observing the change in the number and height of 10 corn plants irradiated to 0 krad, 10 krad, 30 krad, and 50 krad.

The effects of [gamma] rays and electron beams on the germination, outgrowth and the synthesis of protein and rna of bacillus pumilus spores were investigated to clarify the difference in the effects of the two types of radiations on bacterial spores. Germination gamma radiation can be useful for the alteration of physiological characters (kiong et al, considering the effects of radiation on plants, the present study was conducted to determine the effects of radiation on wheat germination and some key physiological and biochemical characteristics of wheat seedlings. Effect of gamma radiation on morphological, biochemical, and physiological aspects of plants and plant products sumira jan, a talat parween, b to siddiqi, a mahmooduzzafar a a department of botany, hamdard university, new delhi-62, india. The purpose of this study was to investigate effect of different dose of gamma rays as induced mutagen on physiological, morphological, and anatomical markers during seed germination and seedling growth of soybean.

Bhendi (abelmoschus esculentus [l] moench) is the most common vegetable crop of the world the genusâ abelmoschus belongs to family malvaceae is represented by 12 species this investigation was carried out toâ the study of different doses of gamma irradiation on bhendi seeds of varieties arka anamika. Impact factor(jcc): 14507 - this article can be downloaded from wwwimpactjournalsus impact: international journal of research in applied, natural and social sciences (impact. Seeds were subjected to irradiation by gamma rays at barc mumbai different doses (5,10,15,20,25kr) were given to the pigeon pea seeds and they were allowed to germinate on filter bridge containing 5ml of distilled water.

The effects of radiation at different doses (0, 50, 100, 150, 200 and 250 gy) of radioactive cobalt (60 co) γ rays on seed germination and seedling growth of lathyrus chrysanthus were investigated under in vitro conditions the results showed that irradiated seeds had increased seed germination percentage, seedling and root lengths, seedling. Gamma radiation exposure at doses ranging from 01 to 1 kgy lead to a decrease by 11–62% of the final germination percentage, by 11–51% of the germination index, by 9–71% of the root length, and by 9–62% of the shoot length. The study concludes that gamma radiation at a low dose stimulates, while a high dose (018 kgy and above) inhibits plant growth and development of wheat index terms: ionizing radiation, wheat, percentage emergence, plant biomass, plant height.

Impact of gamma rays on the germination

impact of gamma rays on the germination The stimulating effects of gamma ray on germination may be attributed to the activation of rna synthesis (kuzin at al, 1975) on coster bean, or protein synthesis (kuzin et al, 1976) which occurred during the early stage of germination after seeds irradiated with 4 k-rad these results are in agreement with the.

Gamma rays in radiotherapy 8b lae eun kim in this unit, we learned that there are 7 types of radiation of the electromagnetic spectrum – gamma rays, x-rays, ultraviolet, visible spectrum, infrared, microwaves and radio waves. 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 irradiated wheat seeds kept their germination speed. The aim of this study was to observe the effects of a dose range of gamma radiation (05 to 10 kgy) over the physiological quality and seed-borne micloflora from two lots of brazilian castor bean seeds. To determine the effects of gamma radiation on the photosynthetic pigments, sugar content and total carbon gain, seeds of cullen corylifolium (l) medik were irradiated with variable doses (0, 25, 5, 10, 15, and 20 kgy) at the rate of 165.

Effect of gamma irradiation on germination: seed germination test after gamma radiation (100, 200, 300 and 400 gy) revealed that mean germination time was decreased with increasing irradiation dose for both genotypes (table 1. In present study results showed the adverse effect of gamma rays on seed germination and plant survival table 1: effect of various doses (kr) of gamma irradiation on percentage of seed germination and plant survival in pisum sativum l. ©societyofappliedsciences impact of gamma rays on the seed germination and seedling parameters of groundnut ( l)arachis hypogaea m aparna , anurag chaturvedi , m sreedhar. Gamma rays as mutagen have induced an inhibitory effect on seed germination chaudhary and singh (1980), satpute and fultambkar (2012) reported similar results in soybean.

This investigation was carried out to determine the effect of gamma irradiation on the subsequent germination and growth of irradiated seeds thirty seeds each of maize, okra and groundnut were irradiated to varying doses of 150, 300, 500, 700, 900, 1000 gy using the 60 co gamma cell irradiator facility at the centre for energy research and. Effects of gamma irradiation on seeds germination, plantlets growth and in vitro best activities were observed with gamma-radiation doses exceeding 150 grays (gy) conclusion: gamma-irradiation of p odontadenius seeds induced reduction of of seeds or the germination rate for each dose was determined by the equation before. Effects of gamma irradiation on germination, growth and charcoal rot disease of sunflower was investigated under greenhouse conditions the sunflower seeds exposed to gamma rays showed slight reduction in germination as compared to un-exposed (non. The effects of dosages ranging from 500 to 10, 000 r on 5 species and 3 hybrids indicated that the maximum safe dosage for normal germination and growth was about 3, 000 r-sugarcane breed inst, coimbatore.
