The susceptibility of Vicia faba to biological radiation effects was investigated by the application of radiation protectors after irradiation. Definite humidity conditions (100, 57, and 2.5% relative humidity) were maintained in the storage of the seeds. Germination rate, sprout growhs root growth, and phase distribution in the root tips were used as indications of the radiation effects. The radiation protectors used were cysteine HCls basic cysteine, and cysteamine. Cysteine -HCl has a strongly toxic effct after seed storage in 100 and 57% relative humidity. Irradiation with 3450 r after storage in 2.5% relative humidity produces significant damage, bui not after storage in 100 and 57% relative humidity. The radiation damage of dry stored seeds is not reduced by cysteine HCl, cysteine -base, or cysteamine. The measurements on the root lengths sprout iength, and mitosis rate agree in this. The results contradict those of previous investigations. (tr-auth)
