Accumulation of N, P, K, Mg, and Ca in 20 species of herbaceous plants in headwater riparian forest

Year: 2018
Type: article
Abstract: ABSTRACT In this study, results of research related to the bioconcentration of N, P, K, Mg, and Ca in shoots of 20 species of herbaceous plants growing along three headwater streams in northern Poland are presented. Shoots of plants and water samples from streams were taken three times during growing seasons in the period between 2012 and 2014. Concentrations of nutrients in plants represented substantial diversity depending on species, sampling period, and the stream. Based on the results, it was found that many plant species take up nutrients in quantities exceeding their physiological demand, which makes them usable in water purification. Potassium (8,118–42,314), nitrogen (11,716–41,645), and phosphorus (11,607–37,459) had the highest levels of bioconcentration factors (BF). Lower values of BF referred to magnesium (1,161–2,973) and calcium (85–393). Results of Kruskall–Wallis test showed significant statistical differences in values of BF between examined plant species in reference to all analysed nutrients, depending on the stream. The highest value of N, P, K, Mg, and Ca BF were found in shoots of Filipendula ulmaria, Athyrium filix-femina, and Ranunculus acris; Veronica beccabunga, Chrysosplenium alternifolium, and Epilobium palustre; Veronica beccabunga, Ranunculus acris, and Chrysosplenium alternifolium; Filipendula ulmaria, Stellaria nemorum, and Epilobium palustre; and Chrysosplenium alternifolium, Geranium robertianum, and Cardamine amara, respectively.
