Plant Growth and Root Morphology Are Affected by Earthworm-Driven (Eisenia sp.) Changes in Soil Chemico-Physical Properties: a Mesocosm Experiment with Broccoli and Faba Bean

چکیده
Abstract Earthworms are “ecosystem engineers” that improve soil water and nutrient content, macroporosity, aeration, provide suitable habitats for microbial populations. This study aimed at defining if the presence of epigeic earthworms ( Eisenia sp.) affected growth development two plant species Brassica oleracea Vicia faba ) via modifications chemico-physical properties. A mesocosm experiment, in which plants were grown outdoors 4 months with or without earthworms, was performed. The selected based on their different habitus root architecture morphology. Soil macroporosity M holding capacity WHC determined. Earthworm-driven bioturbation B measured by filling mesh bags artificial soil. Earthworm abundance biomass, together morphometric parameters (root leaf morphology imaging microscope techniques), end trial. increased (on average +16%) +9%) this accompanied a remarkable degree . In most cases, enhanced studied, significant positive influence majority shoot traits. increase stomatal density +24%) occurred leaves both earthworms. Our results confirmed hypothesis sp. had effect growth, independently from cultivated, these growth-promoting effects mediated changes parameters. By taking into account essential role maintaining healthy soils vegetation they support, can become more resilient against environmental perturbations climate change.

Earthworms are an important component of soil fauna because of their fundamental impact on soil physical, chemical and biological properties. To evaluate the effects of earthworms on some soil chemical properties as well as plant growth indicators, an experiment was carried out in a completely randomized design in greenhouse conditions. The first factor involved the presence or absence of earth...

Plant height of sunflower is a major agronomic trait affecting crop performance in the field and its adaptation to mechanical harvest. Field experiments were conducted to study the effect of foliar application of paclobutrazol (PBZ) at 12.5 g ai/ha, mepiquat chloride (MPC) at 25.0 g ai/ha and chlormequat chloride (CCC) at 1,500 g ai/ha in single or double applications on sunflower plant mor...

Biochemical biomarkers are widely used for the monitoring environmental quality since they can act as early warning signals, for potential ecosystem degradation caused by contaminants. In order to investigate the acute and chronic effects of a commercial formulation of glyphosate on antioxidant defenses (glutathione peroxidase, GPx; glutathione-S-transferase, GST; and reduced glutathione, GSH) ...
