Germination rate and longevity of seeds of Aldrovanda vesiculosa and Utricularia vulgaris
Original language description
The aim of this study is to compare the survival and germination rate of Aldrovanda vesiculosa and Utricularia vulgaris seeds exposed in nylon bags on top of a bottom sediment or slightly buried in it in a sand-pit pool in the Czech Republic for 11 months. The seasonal seed exposure on the top soil or 1-2 cm deep in the sediment had no influence on seed longevity and subsequent germination rate in Aldrovanda and U. vulgaris seeds. This indicates that a deeper anoxia is not harmful for these seeds. For both species, the germination rate in single bags was highly variable. The longevity of Aldrovanda seeds under natural conditions in water can be very variable and be shorter than one year but also longer than 2-3 years. The factors which decide seed longevity might be the population origin (temperate vs. subtropical), plant batch, or natural conditions on the bottom or in the sediment.
