Abstract

Cotinus coggygria Scop. is widely used in ethnopharmacology such as antiseptic, anti-inflammatory, antimicrobial, hepatoprotective, as well as for countering diarrhea, gastric and duodenal ulcers. Total phenols, flavonoids and tannins were determined as the main group of biologically active compounds. Tannins, however, have proven mutagenic in different studies.

Highlights

Root biomass is of paramount importance to the contribution of plants to organic carbon in soils and to the real benefits of climate change mitigation methods [1]
Basal area: The analysis of variance showed a significant difference (F = 8.87, P = 0.043 < 0.05) between the average basal areas within the stands. It is highest in Khaya senegalensis stands with (11.56 ± 0.57 m2/ha) and gradually decreases in Burkea Africana stands (8.97 ± 0.35 m2/ha) towards Anogeissus leiocarpus stands with (5.08 ± 0.22 m2/ha) and Piliostigma reticulatum stands with (2.94 ± 0.13 m2/ha) (Table 2)
The results show that the total large and fine roots biomass is higher in Khaya senegalensis stands

Summary

Introduction

Root biomass is of paramount importance to the contribution of plants to organic carbon in soils and to the real benefits of climate change mitigation methods [1]. The amount of root biomass, and its carbon concentration, should be considered when trying to measure the carbon reserve of a plant [2]. The two main functional roles of the roots are the acquisition of nutrients and water [4]. The woody roots with bark have rather an anchoring role as well as means of transportation and reserve of nutrients. Soils are a major reservoir of carbon [7]. As an indicator of soil health, soil organic carbon is important for its contributions to food production, climate change mitigation and adaptation, and the achievement of sustainable development goals [8].
