Resource sharing in clonal plants - a review of labelling studies
Nováková, Tereza Anna ; Duchoslavová, Jana (advisor) ; Weiser, Martin (referee)
Clonal plants are characterised by their ability to reproduce without sexual reproduction. This is done by the formation of daughter rhizomes or ramets. By maintaining a functional link between them, ramets can share information and resources. The effect of sharing on the growth of clonal plants by sharing can be investigated using biomass experiments. To follow the movement of substances in more detail, labelled substances are used. I will discuss the work on tagging substances and recording their translocation in this thesis. These are carbon, water, nitrogen, phosphorus and calcium. The translocation of substances appears in many cases to be in the direction from the parent ramet to the daughter ramet, but there are plants translocating in the opposite direction. This is influenced by many factors such as plant species, anatomical structure, the age of the ramets and their current needs, as well as abiotic factors and the mobility of the particular element. Water as a carrier medium for minerals may also indicate some dependence of one on the other during translocation. In the future, it would be useful to add comprehensive information on sharing in individual species. Information on how sharing changes during ontogeny, multi-element clonal fragments and tracking of multiple elements in a plant...
