Density control in Potamogeton perfoliatus L. and Potamogeton pectinatus L.

Comparison of methods for measuring production by the submersed macrophyte , Potamogeton perfoliatus L

Six conventional methods for measuring primary production of submersed vascular plants were compared to test for previously suggested inherent shortcomings in the O,-exchange techniques. Production was measured for experimental populations of Potamogeton perfoliatus L., from upper Chesapeake Bay in five comparative studies, each including an O,-exchange method. All techniques tested (14C incorp...

Modelling the clonal growth of the rhizomatous macrophyte Potamogeton perfoliatus

Macrophytes play a crucial role in the functioning of lake ecosystems. Until now most macrophyte models neglected the fact that the majority of macrophyte species expand clonally during the growing season. Inclusion of a detailed description of clonal growth in models can facilitate our understanding of space occupation and patch expansion and predict future macrophyte development. “CLOMO” is a...

DNA barcoding reveals a new record of Potamogeton distinctus (Potamogetonaceae) and its natural hybrids, Potamogeton distinctus × Potamogeton nodosus and Potamogeton distinctus × Potamogeton wrightii (Potamogeton ×malainoides) from Myanmar

Indo-China floristic region is among the 34 richest floristic regions of the world, and its plant diversity is still under investigation. Here we report a new record of an aquatic plant, Potamogetondistinctus, from Myanmar, a part of the region, that is detected by means of DNA barcoding method. The molecular method further identified the other specimens as hybrids of Potamogeton: one is Potamo...

Potamogeton pectinatus Is Constitutively Incapable of Synthesizing Ethylene and Lacks 1-Aminocyclopropane-1- Carboxylic Acid Oxidase1

Spatio-temporal dynamics and plasticity of clonal architecture in Potamogeton perfoliatus

Aboveand below-ground clonal growth architecture was compared for two neighbouring patches of Potamogeton perfoliatus L. in Lake Constance, representing typical sparse and dense growth types. A detailed map of individual ramets and their corresponding rhizome network was produced and the seasonal development of ramet sprouting and rhizome growth was reconstructed. Rhizomes extended at rates ran...
