【摘要】 基于极低温对种子γ辐射效应的影响,研究了液氮低温(-196℃)单因子的生物学效.发现液氮处理冬小麦风干种子,不仅有损伤效应,也有刺激增产和诱变作用.实验结果表明:在液氮中进行种子γ照射应考虑这些因素,并对发展中的低温生物学也提出了有待研究的新问题.更多还原

【Abstract】 Based on the influence of low temperature upon the seed radiated by garma ray, we have studied the biological effect of seed when only under-196℃. The results show that liquid nitrogon not only damaged airdry wheatseeds, but also induced increase of wheat production and the offect of mutation. This fact is helpful to the study of radiating effect under extremoly temperature, and also presents a new problem of the devoloping low temperature biology.更多还原
