The reaction of barley seeds (Nur and Grace varieties) to γ-irradiation in the dose range of 2-50 Gy was studied. The length and weight of a root, the length of a seedling and germination rate were investigated. The dose range in which we observed stimulation of plant development was evaluated. It was shown that the increase of root and seedling sizes after irradiation of seeds at stimulating doses is associated with the rise in the developmental speed, rather than with their earlier germination. Also the effects of a dose rate, a quality of seeds, humidity and a period of storage on the manifestation of radiation exposure were studied.
研究了大麦种子（努尔和格雷斯品种）在2-50戈瑞剂量范围内对γ辐射的反应。对根的长度和重量、幼苗长度和发芽率进行了研究。评估了观察到植物发育受到刺激的剂量范围。结果表明，在刺激剂量下照射种子后根和幼苗大小的增加与发育速度的提高有关，而不是与它们更早发芽有关。还研究了剂量率、种子质量、湿度和储存期对辐射暴露表现的影响。
