Drying of fibrous roots strengthens the negative power relation between biomechanical properties and diameter

Aims Test the effects of root drying on biomechanical properties of fibrous roots. Methods Tensile strength and Young’s modulus of Festuca arundinacea roots were tested after full hydration and during progressive drying. Root diameter, water loss, and water content were measured for all treatments....

Zusammenfassung:Aims Test the effects of root drying on biomechanical properties of fibrous roots. Methods Tensile strength and Young’s modulus of Festuca arundinacea roots were tested after full hydration and during progressive drying. Root diameter, water loss, and water content were measured for all treatments. Results Hydrated roots showed weak relations between biomechanical properties and diameter. After only 30 min air-drying, both tensile strength and Young’s modulus increased significantly in thin roots (
