Abstract

This study aimed to identify leaf sheath function through the investigation of effect of removal times and removed number of leaf sheath on growth and flowering in gladiolus. The leaf sheath influenced on the growth and flowering regardless of light condition at early growth stages. When total leaf sheath were removed in early growth stages, flower stalk length and spike length remarkably decreased. Whereas days of flowering were little different by leaf sheath removal. Also when removed numbers of leaf sheath were 1, 2 and 3, the growth and flowering were little different compared to control. But when removed numbers of leaf sheath were 4, flower stalk length decreased above 25cm compared to others treatment, spike length and number of flower decreased and stem diameter became thick abnormally.

글라디올러스의 생육에 있어 엽초의 역할을 알아보기 위해 제거시기와 제거수를 달리하여 엽초제거 한 후 생육반응을 조사한 결과, 생육초기의 광조건에 관계없이 엽초를 모두 제거함으로써 화경장과 화수장이 짧아졌고 개화수도 적어졌으며 특히 제거시기가 빠를수록 생육이 현저하게 저조해졌다. 그러나 엽초제거에 따른 개화소요일수는 차이를 보이지 않았다. 엽초를 엽위별로 제거한 처리구에서 엽초 1, 2 및 3매를 제거한 것은 생육 차이를 보이지 않았으나 글라디올러스의 초장 생장에 비례적으로 자라난 4번째 엽초를 포함하여 제거한 엽초 4매 제거구에서 타 처리구에 비해 화경장이 25cm이상 작아졌으며 화수장도 짧아지고 개화수도 적어졌다. 또한 줄기기부도 비정상적으로 굵어졌다.
