Abstract

The pollination system of Bupleurum latissimum Nakai (Apiaceae) was investigated in the natural population of Korea. The various insects of 19 species, 11 families, 5 orders visited the flowers of B. latissimum. Episyrphus balteatus and Lasioglossum occidens were considered as the most effective pollen vector which have associated specially with B. latissimum. The visitation frequency peaked at 10 AM - 13 PM and no visitor was recognized during night time. The flowers of B. latissimum last during only three days and they are protandry. It is also confirmed that the flower of B. latissimum is self-compatible and cross-pollination by vectors is critical for successful seed setting.

환경부 멸종위기종인 섬시호(Bupleurum latissimum)를 현지 내에서 보다 효과적으로 보존할 수 있도록 종합적인 종생물학적 정보를 수집하고자, 섬시호의 수분기작 및 수분매개자의 특성을 조사하였다. 섬시호는 5월 말에 개화하며, 꽃은 개화된 상태로 3일간 지속되었다. 꽃은 웅예선숙으로 수술이 성숙한 개화 1-2일째에 암술은 작은 돌기 형태를 이루었다. 꽃이 지기 시작하는 3일째부터 화주가 성숙하여 길게 나오고, 꽃잎은 노란색에서 붉은색으로 변하며 탈락하였다. 섬시호를 방문하는 곤충은 총 5목 11과 19종이었으며, 그 중 가장 효율적이며 주된 수분매개자는 호리꽃등에(Episyrphus balteatus)와 흰줄꼬마꽃벌(Lasioglossum occidens)이다.
