Abstract
The indole-3-acetic acid(IAA) oxidase activity of shoot and root tips of etiolated pea seedlings (Pisum sativum L. var. Sparkle) during and after chilling was determined. The IAA oxidase level of root tips was 4 to 15 times as high as that of shoot tips. During chilling the seedlings apical and subapical 5 mm shoot sections increased in IAA oxidase activity but apical and subapical 5 mm root sections decreased. When chilled plants were returned to
저온이 IAAO의 활성에 미치는 영향을 구명하기 위하여 암실(暗室)에서 재배한 완두(Pisum sativum L. var. Sparkle)의 유묘(幼苗)를 재료로 저온처리 기간과 그 후의 IAAO의 활성변화를 측정(測定)하였다. 줄기의 끝 5mm 부위의 IAAO활성이 그아래 5mm 부위의 그것보다
