Barley seeds were irradiated in the active zone of the reactor at 500 watt, at favourable flux of fast neutrons in the dose interval of 823--2144 rad. Seeds after irradiation were "cooled" for 48 hours, then germinated, and the length of shoots of the seven days old seedings was measured. The value of the half lethal dose is 1130 rad, estimated from the growth curve. There is a well-defined relation of chlorophyll content (calculated for fresh weight unit) to the dose used. It was concluded from the phenotype of the leaves that the decrease of chlorophyll content was due first of all to the presence of chlorophyll-less cells and cell lines and not to the decrease of chlorophyll content of the individual cells. Irradiation yielded genetically defected cells.
大麦种子在反应堆活性区以500瓦功率、在剂量区间为823 - 2144拉德的快中子有利通量下进行辐照。辐照后的种子“冷却”48小时，然后发芽，并测量7日龄幼苗的芽长。根据生长曲线估计半致死剂量值为1130拉德。叶绿素含量（以鲜重单位计算）与所用剂量之间存在明确的关系。从叶片表型得出的结论是，叶绿素含量的降低首先是由于无叶绿素细胞和细胞系的存在，而不是单个细胞叶绿素含量的降低。辐照产生了基因缺陷细胞。
