감마선과 속중성자를 조사한 밀종자의 저장기간과 저장온도가 발아후 유묘생장에 미치는 영향

EFFECTS OF TEMPERATURE AND DURATION OF POST-IRRADIATION STORAGE ON SEEDLING HEIGHT OF WHEAT

본 실험은 소맥품종 Weibull's Svenno종자(수분함량 11.3%)에 감마선과 속중성자를 조사한후 일정기간의 저장효과를 저장시 온도와 관련시켜 조사한 결과이다. 감마선이나 속중성자조사에 의하여 모두 묘생육은 저장기간의 연장에 따라서 감소되었고 선량구에서는 그 정도가 더욱 크게 나타났다. 저장온도효과에 대한 묘생육장해는 높은온도(4$0^{\circ}C$)구에서 크게 보였다. 이의 결과로서는 명확한 저장효과를 인정할 수 있었다.

The experiment was carried out to investigate post-irradiation storage effect which was related to temperature(i.e. at 2$^{\circ}C$, 17$^{\circ}C$ and 4$0^{\circ}C$) on wheat seeds; Weibull's Svenno, treated with gamma-ray and fast neutron. Results obtained showed that the seedling height in both radiation sources was decreased with prolongation of storage period, especially when the seeds were treated with high dosage and stored at high temperature(4$0^{\circ}C$). The results of this trial, however, showed that storage effect was influenced by irradiation dose, temperature and storage time.
