Original title:
The Effect of P Enrichment on Exudate Quantity and Bioavailability - a Comparison of Two Macrophyte Species
Authors: KUBEŠOVÁ, Jaroslava
Document type: Rigorous theses
Year: 2016
Language: eng
Abstract: A study on rhizodeposition rates and rhizodeposits bioavailability (microbial respiration, N mineralization and phosphatase activity) of two macrophyte species with different life strategies (stress-tolerator and competitor) was conducted. Research was carried out in tropical marshes of Belize; results from the field were supported by 13C partitioning mesocosm study. The stresstolerant Eleocharis spp. released more C from roots than Typha domingensis and this C was more biodegradable. The two species responded to P enrichment differently. While Eleocharisspp. invested more assimilated C to the belowground (roots, rhizomes and rhizodepositions) after P fertilization, in T. domingensis the belowground C investment decreased. The effect of plant species was larger than the effect of P enrichment. Eleocharis spp., adapted to growth under low nutrients, invests more carbon into exudation a promotion of its microbial communities in the rhizosphere while competitive T. domingensis spends more fixed C on its own growth and metabolism.
