| Description
| - Jsou prezentována ekofyziologická sledování masožravých rostlin na mokrých půdách. Radiální ztráta kyslíku z kořenů rosnatkovitých do anoxického média byla poměrně nízká (0.020 - 0.070 ?mol (O2) m-2 s-1) v apikální zóně, ale hodnoty přibližně o řád vyšší byly zjištěny v kořenech Sarracenia rubra a pastech Genlisea violacea. Rychlosti aerobní respirace 1.6 - 5.6 ?mol kg-1f.m. s-1 byly změřeny v apikálních částech kořenů 7 druhů masožravých rostlin a 0.4 - 1.1 ?mol kg-1f.m. s-1 v pastech Genlisea. Podíl kyanid rezistentní respirace u všech druhů činil 65 - 89 % z celkové hodnoty. Průměry exudace vody z odříznutých kořenů 12 druhů masožravých rostlin byly v rozsahu 0.4 - 336 mm3 kg-1f.m. s-1. Exudace vody byla necitlivá k respiračním inhibitorům. Kořeny masožravých rostlin jsou fyziologicky velice aktivní a dobře adaptovány k přežití trvalé anoxie půdy. (cs)
- Various ecophysiological investigations on carnivorous plants in wet soils are presented. Radial oxygen loss from roots of Droseraceae to an anoxic medium was relatively low 0.020 - 0.070 ?mol (O2) m-2 s-1 in the apical zone, while values of about one order of magnitude greater were found in both Sarracenia rubra roots and Genlisea violacea traps. Aerobic respiration rates were in the range of 1.6 - 5.6 ?mol kg-1f.m. s-1 for apical root segments of seven carnivorous plant species and 0.4 - 1.1 ?mol kg-1f.m. s-1 for Genlisea traps. In all species, the proportion of cyanide-resistant respiration amounted to 65 - 89 % of the total value. Mean rates of water exudation from excised roots of 12 species ranged between 0.4-336 mm3 kg-1f.m. s-1. Exudation from roots was insensitive to respiration inhibitors. Carnivorous plant roots appear to be physiologically very active and well adapted to endure permanent soil anoxia.
