Distribution and Resorption Efciency of Macroelements (N, P, K, Ca, and Mg) in Organs of Rumex alpinus L. in the Alps and the Giant (Krkonoše) Mountains.

Popis výsledku v původním jazyce

Rumex alpinus, an alpine nitrophilous species, is a troublesome weed in pastures. Nutrient uptake and distributions in theorgans of Rumex alpinus are not well-studied. We aimed to determine the distribution of macroelements in organs of Rumexalpinus together with the nitrogen-phosphorus potassium ratio (NPK) and the resorption efficiency of N, P, K, calcium (Ca),and magnesium (Mg) in the Alps of Austria, Italy, and the Krkonoše (Giant) Mountains, Czech Republic. The pseudo-totaland plant-available N, P, K, Ca, and Mg in soils and organs of Rumex alpinus (emerging, mature, and senescent leaves, petioles,stems, and rhizomes) were extracted with aqua regia and Mehlich-3 procedures, respectively, followed by inductivelycoupled plasma-optical emission spectrometry. The contents of total and available macroelements in the soils reflected highvariability with localities. There was a significant effect of locality and organs on the element contents, indicating differencesin nutrition. Rumex alpinus exhibited higher N and P contents in emerging and mature leaves than in the senescentcompared to Ca and Mg. The N:P and N:K ratios in the mature leaves were within the normal range but were indicative ofcomparatively higher demand for P. The mean resorption efficiency for N, P, and K was 52, 50, and 22%, respectively, lowerthan values for most terrestrial plants (62, 65, and 70%). The relatively high availability of macroelements in soils and plantorgans with low N, P, and K resorption efficiency indicates a high N, P, and especially K-demanding species of Rumex alpinus.
