Abstract

The allelopathic potential of medicinal plant Filipendula vulgaris Moench, originated from two natural habitats: calcareous grasslands and humid meadows, was investigated using radish (Raphanus sativus L. var. radicula Pers.) as a model plant. Suppression influence of aqueous extracts at concentrations: 1%, 5%, 10%, obtained separately from under and aboveground parts of the species, was studied testing germination capacity, biomass and biometry of seedling, and electrolyte leakage. Additionally, two cultivars of the radish were used to test the sensitivity of frequently used plant in the laboratory tests. This study revealed the inhibiting effect of high concentration aqueous extracts from F. vulgaris organs on the germination of radish. It was significant for seed vigour index, speed emergence, germination stress tolerance index, and mean germination time. However, the stimulating effect of 1% of aqueous extracts from dropwort roots and shoots on the germination indexes was documented. Similarly, low concentration extracts had a positive effect on seedling elongation which was visible in biometric analyses and inhibition percentage index but it was not so obvious in the biomass analyses. In general, the aboveground extracts from dropwort grown on calcareous grassland demonstrated higher allelopathic potential than extracts from underground parts and meadow habitat.

Highlights

Medicinal plants have a long history as a source of potential therapeutic agents, that have been incorporated into modern medicine (e.g. Kamboj, 2000; Tapsell et al, 2006; Verma and Singh, 2008; Atanasov et al, 2015)
A decrease in seed germination capacity was observed with the increase in the concentration of aqueous extracts
The smallest differences were found between the control and 1% of Filipendula vulgaris root and shoot extracts regardless of the habitats

Summary

Introduction

Medicinal plants have a long history as a source of potential therapeutic agents, that have been incorporated into modern medicine (e.g. Kamboj, 2000; Tapsell et al, 2006; Verma and Singh, 2008; Atanasov et al, 2015). Medicinal plants have a long history as a source of potential therapeutic agents, that have been incorporated into modern medicine It is estimated that almost 53,000 flowering plant species are considered medicinal plants (Wakdidar, 2004). They are used mainly due to their natural compounds with biological activity that have a positive effect on maintaining human health. Secondary metabolites in medicinal plants have been reported as potent growth inhibitory agents indicating that such plants serve as a storehouse for allelopathic compounds (Batish et al, 2006). There is a growing interest to estimate the allelopathic potential of medicinal plants Received in revised form: 09 Dec 2020.
