Abstract

•	Biochar application decreased soil exchangeable Na⁺ and Ca²⁺, but increased soil exchangeable K⁺ and electrical conductivity.
•	Biochar increased apoplastic pH, but reduced root growth, stress damage and stress response during drought for the drought-sensitive KN5585.
•	Biochar improved osmotic protection, trehalose accumulation, and fresh weight during drought for the drought-tolerant Mo17.
