초록

여러가지 선량(線量)의 방사선조사(放射線照射)가 감자 박편(薄片)$(1\;cm{\times}2\;mm)$ 의 치유조직(治癒組織) 형성에 미치는 효과를 무균 상태하에서 조사(調査)하였다. 세포분열은 선량(線量)이 증가함에 따라 점차 억제되었고 16 krad 처리에서는 완전히 억제되었다. Solanine 함량은 선량(線量)에 따라 유의적(有意的)인 차이를 나타내지 않았다. 방사선조사(放射線照射)에 의하여 감자 괴경(塊莖) 내에 유기(誘起)된 carbonyl 화합물로부터 생성된 2,4-dinitrophenylhydrazone 침전물을 gas chromatograph 로 분리한 결과 formaldehyde 및 acetone 은 고선량(高線量)에서만 증가하는 경향을 보였다.

Effect of various dosages of gamma ray ranging from 0 to 16 krad on wound periderm formation was investigated with aging potato tuber slices $(1cm{\times}2mm)$ under aseptic condition. Cell division was gradually inhibited with increasing dosage, and completely prevented with 16 krad treatment. Solanine content was not significantly different due to dosages. Gas chromatographic separation of 2,4-dinitrophenylhydrazone precipitate from radiation-induced carbonyl compounds in potato tubers showed that formaldehyde and acetone tended to be increased only with high dosages.
