The effect of temperature on the phenology of germination of Isoetes lacustris
Original language description
Isoetes lacustris (quillwort) is an aquatic macrophyte commonly dominating oligotrophic softwater lakes in Europe. Reproductive ecology of a relic population of quillwort based on spore germination was studied in an acidified mountain lake in the Czech Republic. In a four-year experiment, we recorded temperature-related temporal changes in micro- and macrospore germination and sporeling establishment in (i) natural in situ conditions in Cerne jezero lake and (ii) in the laboratory at various temperatures. Germination of both micro- and macrospores increased gradually over four consecutive growth seasons. Several annual cohorts of germinating macrospores born together in a sporangium indicate that spores remain viable for up to several years and the formation of a spore bank. Minimum temperature necessary for germination was lower for microspores (6 degrees C) than macrospores (12 degrees C) and this ensured the availability of spermatozoids for the fertilization of the long-living macr
