Distribuce solí v biomase Typha latifolia vlivem působení fytohormonů

Abstract

The phytoremediation ability and the ability to tolerate a saline environment in broad-leaved cattail (Typha latifolia) is already known also from my bachelor thesis. However, this work examines whether the application of NAA has an effect on the distribution of salts in its biomass. The distribution of Na, K, Ca, Mg, Fe in roots, rhizomes and leaves was investigated in 18 samples that were grown in self-watering pots with expanded clay as hydroponics in a greenhouse under controlled conditions. During the 3 weeks of the experiment itself, 340mM NaCl was applied to 9 samples and 10-5M NAA was applied to 5 of them, 340mM NaCl was not applied to the remaining 9 samples, but 10-5M NAA was applied to 5 of them. Temperature, pH, conductivity, ORP, dissolved oxygen concentration and chloride concentration were monitored in the solutions in the flower pot reservoirs.
