Bonus 大麦种子对γ射线的敏感性依下列顺序递减:4.7%H_2O、50kg·cm~(-2)O_2>4.7%H_2O、用充氧的水浸泡>8.3%H_2O、浸泡于充氧的水中。在突变频率、不育性、苗高和根长的下降方面,辐射敏感性也以相同的顺序递减。在充氮条件下,含水量14.2%的种子是最有抗性的。遗传研究的结果指出:叶绿素突变和不育性方面的氧增强率(OER)范围为5—7,与苗高下降的 OER 是相同的。苗高主要是生理性状。试验结果都按膜或 DNA-膜复合体的损伤作用进行了讨论。膜和 DNA-膜复合体以某种方式参与了大麦种子中低线性能量转移(LET)辐射的突变形成。
The sensitivity of Bonus barley seeds to γ-rays decreased in the following order: 4.7% H 2 O, 50 kg · cm -2 O 2> 4.7% H 2 O, soaked in oxygenated water with oxygenated water> 8.3% H 2 O. Radiation sensitivity also decreases in the same order in terms of mutation frequency, sterility, seedling height and root length decline. Under nitrogen conditions, seeds with a water content of 14.2% were the most resistant. The results of the genetic studies indicate that the range of oxygen uptake (OER) in terms of chlorophyll mutations and sterility ranges from 5 to 7, which is the same as the OER with reduced seedling height. Seedling height is mainly physiological traits. The results are based on the membrane or DNA-membrane damage of the role of the body were discussed. Membrane and DNA-membrane complexes are somehow involved in the formation of mutations in low linear energy transfer (LET) radiation in barley seeds.
