POLLEN MORPHOLOGY OF THE POLISH SPECIES OF THE FAMIL Y CAPRIFOLIACEAE. PART 1.

摘要

This paper contains results of studies on pollen morphology of 5 Polish species of the family Caprifoliaceae (genera Sam- bucus and Viburnm). The pollen has been examined with LM and SEM. Besides detailed descriptions, series of micrpohoto- graphs are presented. All examined species have small to medium-sized grains, with prolate polar axis, reticulate ornamen- tation (at least in mesocolpia), relatively long ectoapertures and with often visible equatorial bridges. Extent of fusion of capita in muri allows to divide observed pollen grains into 2 subtypes: one for examined Sambucus species and for V. opulus, the second for V. Lantana.
