Résumé

Root penetration ability is critical for plant growth and development. When roots encounter soil impedance, hormones are activated that affect cells and tissues, leading to changes in root morphology and configuration that often increase root penetration ability. Factors, such as root system architecture, root anatomic traits, rhizosphere exudation and root-induced phytohormones, influencing root penetration ability and how they affect plant performance under soil impedance were summarized. Root penetration ability affects plant capturing water and nutrients, and thus determines plant performance and productivity in adverse environments. Great efforts have been made in searching for the underlying mechanisms of root penetration ability, and tools have been developed for phenotyping variability in root penetration ability. Therefore, with the continued development of agroecosystems based on the advocated low input costs and controlled tillage, crops or genotypes of a crop species with stronger root penetration ability may have the potential for developing new varieties with enhanced adaptation and grain yield under mechanical impedance in soil.
