“…The significant reduction in seed moisture content (9,68%) began at 100 Gy of gamma rays and continued to decline to up to 4,04% at 500 Gy. Seed moisture at the time of radiation plays an significant role in the expression of radiation effects (Ohba, 1961;Bhattacharya and Joshi, 1977). Seeds are dry and want to absorption of water and hydrolytic enzymes are activated (Bewley, 1997).…”

This study compares the effects of different doses gamma radiation on crude oil yield and moisture of different six variety sunflower (Helianthus annuus L.) seeds. As materials, sunflower variety Ege-2001, Turay, AS-508, Tunca, TR-3080 and Tarsan-1018 seeds were used and irradiated with doses of 100, 200, 300, 400 and 500 Gy gamma radiation. Control groups were not subjected to gamma radiation. Irradiation was performed in a cesium (Ce 137 ) Gammacell 3000 Elan source, dose rate about 9.75 Gy/min (2900 Ci) in the Pamukkale University Faculty of Medicine in the department of the radiological. Moisture amount of seeds were also measured by AOCS standarts. Extraction of the seeds was done with soxhlet apparatus using petroleum ether by hot continuous extraction for 6 hours. It was found that the highest moisture rate in 100 Gy for all seeds variety. The moisture rate ranged between 3.00 and 9.68% in TR-3080 and Ege-2001, respectively. According to our results, the moisture content of the seed negatively affected by gamma radiation. The significant reduction in seed moisture content (9.68%) began at 100 Gy of gamma rays and continued to decline to up to 4.04% at 500 Gy. The crude oil yield showed not a important increase in 100 and 200 Gy doses. The result showed that the highest crude oil yield was also obtained from 400 Gy and 33.49% in Ege-2001 seeds.

“…Ionizing radiation can involve oxidative stress by producing primary (•OH, H•) and secondary (H 2 O 2 , O 2 • -) free radicals (Esnault et al, 2010). While minimum radiosensitivity was observed at intermediate moisture content, increased radiosensitivity was obtained at lower or higher moisture levels rice seeds (Bhattacharya and Joshi, 1977). It was observed that there was marked increase in mutation frequency as the moisture content decreases below 14% in barley seeds (Mba et al, 2010).…”

Walnut (Juglans regia L., 2n=2x=32, Juglandaceae) is a deciduous temperate fruit species with an increasing economic importance and health benefits. The effective mutation dose (EMD) was not determined for 'Chandler' budwoods. The objective of this study was to determine the radiosensitivity of walnut budwoods to cobalt-60 gamma ray. One-year-old budwoods of 'Chandler' walnut cultivar carrying 4-5 buds in 20 cm in length were irradiated with cobalt-60. The gamma irradiation and chip budding were performed three different times. The budwoods were irradiated (1) with 0,

Radiation induced stimulation of plating efficiency of free plant cells was observed following irradiation with X-rays (1.25 Gy, dose rate 3.1 Gy.nin(-1)) and fission neutrons (1.5 Gy, dose rate 0.05 Gy.nin(-1)). The dose range where the radiation stimulation effect is manifest is inversely correlated with the applied dose rate.The results are discussed in view of the radiation induced stimulation as it is applied in agricultural practice.
