Description	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 °C) than macrospores (12 °C) and this ensured the availability of spermatozoids for the fertilization of the long-living macrogamethophytes whenever they produced archegonia during growing season(s). Macrogametophyte development started between July and October and sporeling development always followed in the next or subsequent springs.The mean length of time when the temperature ( 12 °C) was high enough for the germination of I. lacustris in Černé jezero lake was 119 days and occurred during the period June to September in 2004–2011.
