Abstract

This study examined the irradiation effect of high energy x-rays on the growth of sprout plants seeds. particularly with regard to acidity, salinity and sugar content change. The experimental groups were one day old sprout plants seeds irradiated with 6MV x-rays at doses of 2, 5, 8, 10 Gy using a linear accelerator. The control group was not irradiated. After two weeks, sprout plants were grown and harvested for component analysis. The acidity of the x-ray irradiated radish and red radish groups were significantly higher than that of the control group and bok choi and buckwheat groups lower than that of the control group. The salinity and sugar content of the x-ray irradiated 5 groups were significantly lower than that of the control group and Soybean and Red radish groups higher than that of the control group. The cause of plants component change were estimated to have occurred by generate basic ions and radiation sensitivity by moisture content. Further genetic studies will be needed to confirm the correlation between high energy x-rays and the cause of plants component change.

본 연구는 고 에너지 X-선을 조사한 새싹식물 종자를 파종 및 재배하여 산도, 염도, 당도, 당산비의 변화를 분석하고 식물의 생장에 미치는 영향을 알아보고자 하였다. 새싹식물 6종의 종자에 각 종자별로 대조군 1개군과 실험군 4개군을 구성하여 6MV X-선을 0, 2, 5, 8, 10 Gy 각각 조사하였다. 조사된 종자들을 파종하고 재배하여 식물의 액을 추출 및 성분분석을 실시하였다. 무순과 적무의 산도는 모두 증가하였고, 청경채와 메밀은 산도가 평균적으로 감소하였다. 다른 종자의 실험군은 대조군과 비슷한 산도로 분석 되었다 새싹식물의 염도, 당도는 평균적으로 감소하였으나, 적무의 염도는 2배 증가하였고, 수분 함량이 높은 콩나물은 당도가 모두 증가하였다. 따라서 고 에너지 X선은 식물의 성분에서 염기성 이온을 생성하고, 수분 함량이 높은 식물은 방사선 감수성이 높아 생장에 영향을 받아 과산화물이 생성되어 식물의 성분 변화에 영향을 미친다고 판단된다. 향후 고 에너지 방사선의 조사에 따른 식물성분의 변화 원인을 알아내기 위한 지속적인 유전학적 연구가 필요할 것이다.
