Abstract

This study was initiated to investigate similarity and intraspecific variation in pollen morphology of korean subgenus. lepidobalanus Endl, of the genus Quercus L. The parameters measured were polar axis length (PL), equatorial width (EW), colpus length (CL) and copus width (CW), and PE (PL/EW) retios were calculated. The cluster analysis based on these variables of this result showed that the similarity between Q. acutissima Carruther and Q. variabilis Blume was the highest. Wide variation in the pollen grain size of Quercus dentata Thunb. ex Murray might imply, the existence of polyploid and/or aneuploid forms. Studies of ploidy levels within species are recommended for Lepidobalanus species.
