Abstract

The pollen morphology of 15 species, 2 varieties and 1 forma belonging to 6 sections of the subgenus Salix was investigated by means of light and scanning electron microscopy. From a pollen-morphological point of view, subgenus Salix is stenopalynous. Species from six sections have been distinguished on the basis of pollen morphology, and a key for their identification using pollen is presented. Based on pollen morphology, S. jessoensis(section Subalbae) is the most distinct of the species studied. Species of section Hurmboldtianae appear to be the most evolved in this subgenus with a closer relationship to section Amygdalinae than any other section of this subgenus.

버드나무아속(亞屬) 6절(節), 15종(種) 2변종(變種) 1품종(品種)에 대(對)한 화분형태(花粉形態)를 광학현미경(光學顯微鏡)(LM)과 전자현미경(電子顯微鏡)(SEM)으로 관찰(觀察) 하였든바 버드나무 아속(亞屬)의 화분(花粉)은 동형(同型) 화분군(花益群)이였으며 화분(花粉)의 형태학적(形態學的) 특징(特徵)에 의(依)하여 6절(節)에 대(對)한 화분(花粉) 검색표(檢索表)를 만들 수 있었다. 또한 Amygdalinae 절(節)과 근녹관계(近綠關係)에 있을 것으로 생각되는 Humboldtianae 절(節)은 본아속중(本亞屬中)에서 가장 진화(進化)된 것으로 보인다.
