Integrated physiological, photochemical and anatomical responses reveal divergent drought-response strategies among herbaceous peony cultivars
Drought responses involve coordination across organs and functional levels, yet integrated cultivar strategies remain poorly resolved in herbaceous peony. Five cultivars, ‘Fen Guan’ (FG), ‘Jing Wang Fen’ (JWF), ‘San Dian Hong’ (SDH), ‘Cai Xia’ (CX) and ‘Xiao Ou’ (XO), were exposed for 30 d to nominal target regimes of...
