YIM, Kyong Bin (Coll. of Agriulture, Seoul National University) Effect of neutron and gamma irradiation on the germination of diploid and tetraploid rye seeds. Kor. Jour. Bot. VI(3):6-14, 1964. Tetraploid rye, Secale cereale 4x, was more tolerant to fast nuetron than diploid rye. Root growth was more suppressed than was seedling height in both diploid and tetraploid rye. A stimmulative effect on the dry weight of the shoot could be observed at very low doses of irradiation. It was the fact that the lower the moisture content of the seeds, the higher the radiosensitivity. Concerning seedling height growth, the effectiveness ratio of N/X equalled about 20.0 in diploid rye and about 18.2 in tettraploid rye, when the 50% dose ratios is used for this quotient calculaiton. |
