How Do Pollen Grains of Convallaria majalis L. Respond to Different Habitat Conditions?

To date, the effect of habitat conditions on characteristics pollen has not been extensively investigated; however, it needs to be remembered that may highly significant for quality their generative reproduction success. It was decided conduct analyses Convallaria majalis as a common species, naturally found in many different forest habitats. Moreover, investigations covered morphology and first time also variability grains this species. The plant material came from 98 natural sites located Poland, nine differing In total, 2940 were analyzed terms five quantitative features (i.e., length longest shortest polar axes–LA SA, exine thickness–Ex, LA/SA Ex/LA ratios) well following qualitative ones: outline shape, sulcus type ornamentation. Our studies revealed most important C. included type, ornamentation, distribution size perforations, LA shape. study showed response investigated ratio Ex these characteristics, which exhibited marked conditions.
