Effects of aluminium toxicity and low pH on the early development of Isoëtes echinospora
Original language description
The responses of the sporelings to the experimental treatments were evaluated and compared with those observed in the lake. The experiments showed that an Al concentration higher than 300 ?g l?1, and high acidity (pH 4), inhibit sporeling growth, in particular resulted in a pronounced reduction in absorptive organs (macrogametophyte rhizoids, roots and root hairs). With increasing concentrations of Al and at pH 4, the ratio of the below-ground to above-ground sporeling biomass decreased to less than 1.The responses of the lake sporelings, rooting in the upper sediment layer, were similar to those exposed to 100?300 ?g l?1 of Al in the laboratory, and reflected the Al toxicity of the lake water.. The quillworts at Plešné Lake survived because adult plants can tolerate these adverse conditions and are very long lived. The population recovered when the pH of the water increased to over 5 and the Al concentration decreased to below 300 ?g l?1.
