Description	Innate and imposed dormancy were characterized in turions (winter buds) of the aquatic carnivorous plant Aldrovanda vesiculosa kept at 3 degrees C over the winter. As a result of the breaking of imposed dormancy by a temperature increase (at 15-20oC), the turions rose to the water surface within 1-3 d and germinated. Turion leaves contained large lacunae and were filled by water over winter. As a result of breaking imposed dormancy, the proportion of gas volume in inner turion leaves rose from 10-20 to 100 of lacunae volume. The aerobic dark respiration rate of the turions [0.74-1.5 micro mol (O2) kg-1(FM) s-1] slightly increased during innate dormancy after 1-2 d at 20 degrees C, while it was almost constant during the breaking of imposed dormancy. The anaerobic fermentation rate of the turions was only 1.5-7 of the oxygen respiration rate and also was constant during the breaking of imposed dormancy. Starch content was greatly reduced for the imposed dormancy.
