The article presents the results of studies a series species identifications genus Lemna (Lemnaceae) conducted in 2019. Duckweed samples were taken from eight localities northern regions Ukraine and identified to using morphological molecular markers (barcoding). A new alien duckweed for Ukraine—lesser (Lemna aequinoctialis Welw.)—was discovered, which this study is devoted. All other belonged ...

The entrainability of Lemna perpusilla CO(2) output by periodic 15 minute red (R) and far red (F) illuminations was tested in low nitrate medium. R every 8 hour, symbolized R/R/R, gives a flat output (no entrainment) as does F/F/F. However, R/-/- (R every 24 hour) entrains rapidly, and F/-/- does so as well, in a similar manner. The effects of R/R/- and F/F/- also resemble each other closely. E...

Microsatellite primers are a valuable tool to use for both observational and experimental studies in numerous taxa. Here, we develop 18 16 microsatellite markers the widespread duckweeds Lemna minor Spirodela polyrhiza, respectively. Only four were not polymorphic when tested on samples from Europe Western Pennsylvania, USA.
