稲における放射線感受性の品種間差異の研究 : 第2報 幼苗長、鞘葉長、花粉稔性、種子稔性の減少と葉緑素突然変異に示された放射線感受性

抄録

Clear varietal differences were observed in the reduction in seedling height and coleoptile length and not in induced pollen and seed sterility and mutation frequencies following exposure of seeds to X-or gamma-rays. Correlation was significant between the sensitivities measured by root length reduction and that measured by inhibition of seedling growth and coleoptile elongation.
