Ecophysiological Parameters of Medicinal Plant Filipendula vulgaris in Diverse Habitat Conditions

Abstract

This study attempts to determine which of the habitats occupied by Filipendula vulgaris creates better conditions for its growth and development. Selected physiological parameters—PSII activity, chlorophyll content, electrolyte leakage, hydrogen peroxide content as well as biomass, the occurrence of mycorrhiza, and soil characteristics—were investigated. Grassland soils had a higher content of macronutrients and a lower concentration of heavy metals. The degree of colonization of F. vulgaris by AMF (Arum type) oscillated around high values in both types of stands. Plants growing on xerothermic grasslands achieved much better fluorescence parameters than those collected from meadows. Similar results were obtained from the analysis of chlorophyll content. The destabilization degree of cell membranes was significantly higher in plants collected in meadows than in grasslands. Biomass analysis showed higher values of these parameters in grassland plants. In the case of the parameters of fluorescence emission, plants growing on grasslands achieved significantly lower values than plants collected from meadows. The analyses carried out showed that better conditions for growth and physiological activity of F. vulgaris are probably associated with grasslands on a calcareous substrate.

A review of significance of allelopathy in anticipating negative climate change effects

“…elatior), as the most well-known invaded species, has the potential to enhance its growth parameters and increase the relative concentrations of allelochemicals including major monoterpenes (DL-limonene 105%, β-myrcene 203%, and 1,3,6-Octatriene 258%) and sesquiterpenes (germacrene-D 138%, β-caryophyllene 421%) in association with CO 2 elevation. It's widely known that allelochemicals play a crucial role in influencing the invasiveness of plants by enhancing their competitiveness and overall fitness (Barabasz-Krasny et al, 2023). This, in turn, determines their global ecological boundaries (Applebee et al, 1999;Bae et al, 2019).…”

“…Additionally, these compounds have the potential to facilitate the successful establishment and proliferation of both native and exotic plants within their respective local or introduced/invaded ranges (Callaway, Ridenour, 2004;Xu et al, 2006;Wang et al, 2010;Zandi et al, 2020). Given the intrinsic advantage of invasive species in competing for environmental resources (Barabasz-Krasny et al, 2023), a raise in atmospheric CO 2 levels could potentially amplify their dominance over native species. This amplification may result in an expansion of their territorial reach, thereby posing a significant threat to native ecosystems and the preservation of natural biodiversity (Choi et al, 2011;Lehoczky et al, 2011).…”

“…These invaders often possess competitive advantages such as rapid growth rates, extensive resource acquisition, and effective defence mechanisms, allowing them to outcompete indigenous plants in their habitat (Fig. 1) (Zenni et al, 2016;Barabasz-Krasny et al, 2023). The displacement and suppression of native vegetation by invasive species can lead to a decline in biodiversity within affected ecosystems (Alldred et al, 2016).…”
