Physiological analysis of Earlistaple 7 and Nan Dan Ba Di Da Hua in response to various durations of salt stress. (A) Leaf relative water content (RWC) levels; (B) Leaf relative electrical conductivity (REC); (C) Leaf chlorophyll-a and chlorophyll-b content; (D) Root Na⁺ concentration; (E) Leaf Na⁺ concentration; (F) Ratio of leaf K⁺/Na⁺ concentration in 200 mM NaCl-treated and non-treated samples. Data represent means ± SE of three independent experiments (n = 3 or 9); * P < 0.05; ** P < 0.01; *** P < 0.001.
