Abstract

The study aimed to identify leaf sheath through the investigation a characteristic of leaf by planting depth and leaf sheath function through the investigation of effect of leaf sheath removals on growth and flowering in forcing of Lilium cultivars. The number of leaf sheath of 'Jolanda', 'Dream Land', 'Casablanca' were 6, 5, 11 in 0cm planting depth and 6, 5, 14 in 6cm planting depth. The number of leaf sheath in 'Jolanda' and 'Dream Land' were little different in according to planting depth. The other hand, the number of leaf sheath in 'Casablanca' were increased 3 when it were planted in 6cm planting depth. As leaf sheath were removed, plant height and stem root growth were decreased in 'Le Reve' and 'Casablanca'. Whereas the growth of basal root and flower number varied among of Lillium and stem diameter, the days of flowering and flower size were little different.

나리속(屬) 식물의 엽초는 품종에 따라 엽위별 형태와 숫자가 큰 차이를 보여 품종별로 식재깊이에 따른 엽초수를 조사하고, 엽초를 제거한 후 생육 반응을 알아보았다. 품종별 엽초는 0cm로 식재한 경우 'Jolanda'는 6매엽, 'Dream Land'는 5매엽과 'Casablanca'는 11매엽으로, 6cm로 식재한 경우 'Jolanda'는 6매엽, 'Dream Land'는 5매엽과 'Casablanca'는 14매엽으로 밝혀져 'Jolanda'와 'Dream Land'는 식재깊이에 따라 엽초수의 차이가 없었으나 'Casablanca'는 6cm로 식재한 것이 0cm로 식재한 것에 비해 엽초가 3장이 더 많아졌다, 한편 엽초를 제거함으로써 'Le Reve'와 'Casablanca' 두 품종 모두 초장이 작아졌으며 stem root의 생육이 나빠졌다. basal root의 생육과 꽃수는 품종별로 다른 양상을 나타냈으며 줄기 직경, 개화소요일수와 꽃의 크기는 차이가 없었다.
