THE RELATION OF SEEDLING HEIGHT TO GENETIC INJURY IN X-IRRADIATED BARLEY SEEDS
Seeds germinated immediately after x irradiation and then grown for 7 days showed a near-normal distribution of seedling heights about the mean. However, when x irradiated seeds were stored at room temperature for 8 days before germination, the seedling height distribution about the mean was skewed and approached the bimodal. Determination of the extent of genetic injury in different seedling height classes in the material subjected to postirradiation storage showed that there was an inverse relation between seedling height and genetic injury. On the average, seeds in the shortest height class evidenced between two and four times as many interchanges and mutations as seeds in the tallest height class. (auth)
