Abstract

The pollen morphology of six taxa of the genus Indigofera in Korea was investigated by light microscope(LM) and scanning electron microscope(SEM). The pollen grains of the genus were monads, prolate spheroidal or subprolate, and trizonocolporate. Sculpture patterns of mesocolpium area were densely microperforate(DMIP) or verrucate with pitted perforate striae(VPPS). Based on sculpture patterns in mesocolpium, apocolpium and colpus areas, three major pollen types of Indigofera were discernible ; Decora, Kirilowii and Koreana. It seemed as if there was some relationship between chromosome numbers and mesocolpium sculpture patterns and the pollen types Decora and Kirilowii were branched out from the pollen type Koreana.

본 연구는 한국에서 생육하는 땅비싸리속 6분류군의 화분형태를 광학현미경과 주사형전자현미경으로 관찰하였다. 본 속의 화분립은 단립이며, 적도면 입상은 약장구형 혹은 아장구형이고, 발아구는 삼공구형이고, 표면무늬는 DMIP상이거나 VPPS상이었다. 본 속은 mesocolpium, apocolpium 그리고 구구 주변의 표면무늬에 따라 Decora, Kirilowii, Koreana 화분형으로 구분되었다. 염색체 수와 mesocolpium 표면무늬에 연관성이 있고, Decora와 Krilowii 화분형은 Koreana 화분형에서 분지된 듯 보인다.
