Abstract

Pollen morphological characteristics of 7 taxa of the genus Aruncus L. (Rosaceae) were examined using scanning electron microscopy (SEM) to evaluate the taxonomic implication within the genus. Aruncus pollen grains were monad, tri-colporate with granular membranes, small in size ($P=8.33-12.57{\mu}m$, $E=8.93-14.40{\mu}m$), amb is sub-circular to circular, suboblate to prolate-spheroidal in shape (P/E = 0.68-1.70). The sexine ornamentation in all studied taxa was basically striate but existence of perforation (striate-perforate: A. dioicus, A. dioicus var. acuminatus, A. dioicus var. astilboides, A. dioicus var. pubescens, A. dioicus var. vulgaris; striate-pstilate: A. dioicus var. aethusifolius, A. gombalanus) and the widths of muri and grooves varied according to the taxa. In particular, relatively short, and sharply crested muri being a distinct feature of A. dioicus var. acuminatus. As a result, the various combination of each pollen characteristics could be useful to identify the some taxa of the genus Aruncus.

개승마속 내 7분류군이 갖는 화분형태학적 형질변이의 분류학적 유용성을 알아보기 위하여 주사전자현미경을 사용하여 자세히 관찰하였다. 본 속의 화분은 단립으로 크기는 소립($P=8.33-12.57{\mu}m$, $E=8.93-14.40{\mu}m$)이며, 극축면에서는 아원형에서 원형의 형태를, 적도면에서는 아단구형에서 약장구형에 걸친 형태를 나타내고(P/E = 0.68-1.70), 과립상 돌기를 지닌 3공구형의 발아구를 갖는 것으로 확인되었다. 화분의 표면무늬는 기본적으로 유선상의 특징을 지니고 있으나, 천공의 유무, 유선과 유선 사이의 너비 등에서는 차이를 보여주었다. 특히, A. dioicus var. acuminatus는 속내의 다른 분류군에 비해서 상대적으로 짧고 높게 솟아있는 유선을 갖는 특징으로 구분됨을 확인하였다. 화분학적 형질을 종합한 결과, 개승마속의 다양한 화분학적 변이의 조합은 속 내 일부 분류군을 구별하는데 유용한 것으로 나타났다.
