The plant's phenotypic plasticity was studied analysing anatomical, morphological, biochemical and physiological characteristics in specimens fromdifferent locations. Floating leaves were thicker, having abundant aerenchyma, lower chlorophyll a+b contents and higher chlorophyll a/b ratio. The relative amounts of total UV-B and UV-A screening compounds per leaf area were high and similar in all forms that indicated possibly saturated amounts. The measurement of fluorescence parameters revealed no disturbance in energy harvesting since the values of potential and effective photochemical efficiencies, photochemical and non-photochemical quenching were similar over the gradient</dc:description><dc:description xml:lang="sl">Amfibijska vrsta Glyceria fluirans se pojavlja v presihajočem ekosistemu Cerkniškega jezera, kjer se poplave izmenjujejo s sušnimi obdobji. Vrsta porašča širok pas na prehodu iz vode na kopno. Na podlagi nekaterih anatomskih, morfoloških, biokemijskih in fizioloških analiz rastlin na prehodusmo ugotavljali fenotipsko plastičnost vrste. Plavajoči listi so bili debelejši, z obsežnejšim aerenhimom, nižjo vsebnostjo klorofila a+b in višjim razmerjem med klorofiloma a in b. Relativna vsebnost UV-B in UV-A zaščitnih snovi na listno površino se med proučevanimi oblikami ni bistveno razlikovala kar kaže na saturirane vrednosti. Izmerjeni parametri fluorescence so odražalinemoten privzem energije, saj so bile vrednosti potencialne in dejanske fotokemične učinkovitosti ter fotokemičnega in nefotokemičnega dušenja podobne na celotnem prehodu iz vode na kopno</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-J1D88190"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-J1D88190" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-J1D88190/b12b8262-5353-435d-b02c-6a4a5acd6f10/PDF" /><edm:rights rdf:resource="http://creativecommons.org/licenses/by-nc-nd/4.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Društvo biologov Slovenije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-J1D88190/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-J1D88190" /></ore:Aggregation></rdf:RDF>
