Abstract

The pollen morphology of 7 taxa, 3 genera of Buxaceae growing in Korea was investigated by means of light(LM) and scanning electron microscope (SEM). The results were as follows ; 1. A key to the genera of Buxaceae on the basis of pollen morphology was provided. 2. Pollen Length that Buxus was $21.9{\mu}m-28.3{\mu}m$, Pachysaradra was $34.9{\mu}m-43.0{\mu}m$ and Sarcococa was $27.2{\mu}m-39.6{\mu}m$ and that muri width and length were $0.3{\mu}m-4.6{\mu}m$, $0.9{\mu}m-4.3{\mu}m$, and that Lumen length was $0.4{\mu}m-2.4{\mu}m$. 3. Sculpture patterns were reticulate (Buxus) and chain shape (Sarcococa and Pachysandra). 4. Aperture type was polyforate.

한국(韓國)에서 생육(生育)하고 있는 회양목과(科)의 3속(屬) 2종(種) 4변종(變種) 1품종(品種)의 화분형태(花粉形態)를 광학(光學) 현미경(顯微鏡)과 주사형전자(走査型電子) 현미경(顯微鏡)을 이용(利用)하여 관찰(觀察)하였던바 그 결과(結果)는 다음과 같다. 1 화분형태(花粉形態)에 의(依)하여 속(屬) 수준(水準)의 화분(花粉) 검색표(檢索表)를 만들수 있었다. 2. 화분립(花粉粒)의 길이는 회양목속은 $21.9{\mu}m-28.3{\mu}m$, 수호초속은 $34.9{\mu}m-43.0{\mu}m$, Sarcococa는 $27.2{\mu}m-39.6{\mu}m$이었으며, Muri의 폭과 길이는 $0.3{\mu}m-4.6{\mu}m$, $0.9{\mu}m-4.3{\mu}m$, Lumen의 길이는 $0.4{\mu}m-2.4{\mu}m$이었다. 3. 표면(表面)무늬 형태(形態)는 회양목속(屬)은 망상(網狀), 수호초속(屬)과 Sarcococa는 사슬상(狀)이었다. 4. 발아구(發芽溝)는 3속(屬) 모두 다산공구형(多散孔溝型)이었다.
