Ecophysiological characterization of dormancy states in turions of the aquatic carnivorous plant Aldrovanda vesiculosa.
Original language 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 to100 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. A temperature increase
