Abstract
Germination ofLemna gibba L. seeds originating from two climatically different regions of Czechoslovakia: (1) South Bohemia, Jordán fishpond: (2) South Moravia, Nesyt fishpond, was examined under both laboratory and field conditions. The influence of water temperature on the rate of germination and the influence of different storage conditions on germination were assessed during 1972–1974. During the first year after ripening, all experimental treatments (i. e. germination at different water temperatures; storage in refrigerator and hibernation in the fishpond prior to germination) except the variant in which the seeds were kept in drought, resulted in roughly 100% germination. The rate of germination increased with increasing water temperature. The seeds lost their germination ability approximately after two years.
