Pollen morphology of three invasive Impatiens species in Europe under varying habitat conditions-a case study from Poland.

ABSTRACT: The effect of the habitat conditions on the pollen features of invasive species has not been studied so far, and may affect the quality of their generative reproduction and contribute to the development of more effective methods of their control. Three species invasive in Europe and Poland were selected for the study - Impatiens parviflora DC., Impatiens glandulifera Royle and Impatiens capensis Meerb. The morphology and intraspecific variability of pollen grains in three Impatiens species growing under different habitat conditions were examined. Specimens were sampled from 198 sites throughout Poland, covering 10 ecologically distinct habitat types. In total, 5940 pollen grains were analysed in respect to the length of the polar axis (P), equatorial diameter (E), exine thickness (Exp), P/
