Plant root morphology and soil biological indicators under primary development of various swards

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2017
Plant nutrition conditions are limited in naturally acidic soil due to harmful hydrogen and aluminium ions. More favourable conditions for plant nutrition (soil liming) will affect root qualitative and quantitative parameters and influence ecosystem ...

Mowing Modulates the Biotic Filter of Expansive Species

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
Management type and expansive species influence plant community diversity in complex ways. Overall increase of expansive species cover acts as biotic filter in reducing the alpha and beta taxonomic and phylogenetical diversity. However, the filtering effect is modulated by management type, being more intense under mown grasslands.

Using in vitro methods to estimate metabolizable energy content of five forage legumes harvested under different defoliation systems / Einsatz von in vitro Methoden zur Schätzung der umsetzbaren Energie in fünf Futterleguminosen aus unterschiedlichen Nutzungssystemen

open access: yesDie Bodenkultur, 2016
Two in vitro methods were tested to establish their potential to predict the metabolizable energy (ME) content of forage legumes: the Tilley and Terry (TT) method and the pepsin-cellulase method (CM). Different samples of white clover (Trifolium repens L.

Evaluating the Quantitative Accuracy and Application of DNA Metabarcoding for Dietary Reconstruction in Ruminants

open access: yesEcology and Evolution, Volume 16, Issue 1, January 2026.
This study assessed the accuracy of DNA metabarcoding using ITS2 and trnL markers to reconstruct sheep diets under controlled feeding trials with high‐ and low‐digestibility forage, and in a secondary trial with low‐level inclusions of Medicago sativa. ITS2 offered higher species‐level resolution, while trnL provided broader taxonomic coverage but less

The formation of fungal associations in a mountain agricultural habitat of Trifolium pratense L. and Dactylis glomerata L.

open access: yesActa Mycologica, 2014
The communities of fungi in the soil, rhizosphere, planosphere and roots of Trifolium pratense L. and Dactylis glomerata L. were examined in pure and mixed crops. The plants were cultivated for four years under mountain conditions .

Plant identity determines pollinator, natural enemy, herbivore, and decomposer abundances in flower plantings

open access: yesEcosphere, Volume 17, Issue 1, January 2026.
Abstract Flower plantings in agricultural landscapes can contribute to sustainable crop production by enhancing pollination and biological control services. However, selecting plant species that promote multiple ecosystem services is challenging, since plants that favor pollinators may not equally foster natural enemies, and potential trade‐offs, such ...

Dalsze studia cyto-embriologiczne di-, tetra- i oktoploidaluych form Trifolium [Further cyto-embryological studies on di, tetra- and octoploid forms of Trifolium]

open access: yesActa Agrobotanica, 2015
In the course of this study no significant differences in the length of pollen-tubes of ecological types collected from natural stations (Trifolium pratense L. var. spontaneum Willk., T. hybridum L. and T.

Isolation, chemical characterization and biological activity of red clover (Trifolium pratense L.) root saponins

open access: yesActa Societatis Botanicorum Poloniae, 2014
Crystalline saponins were isolated from red clover (Trifolium pratense L.) roots. They were a mixture of two glycosides showing no haemolytic or fungistatic activity. Acid hydrolysis of these saponins yielded soyasapogenols B. C. D. E and F and rhamnose.
