Oat species and interspecific amphiploids show predominance of diploid nuclei in the syncytial endosperm

The paper shows that diploid nuclei dominate the syncytial endosperm in oat species and amphiploids, with amphiploids showing weaker dominance due to aneuploid events.

Synanthropic flora in the vicinity of the mediaeval Castle Kolno, Stare Kolnie near Brzeg, southwestern Poland

The paper analyzes plant diaspores from a medieval castle site to identify species associated with human activity and their distribution in micro-niches.

A contribution to the variability of Prunus spinosa L. in the vicinity of the mediaeval Castle Kolno, near Brzeg, S-W Poland

The paper analyzes the variability of stone and leaf characteristics in modern and fossil Prunus spinosa L. forms near Castle Kolno, finding developmental relationships and taxonomic potential in leaf morphotypes.
