Processing methods and physiological and biochemical indicators after cold treatments at various time points. (A) Two-month-old wild apple seedlings growing in tissue culture bottles (left); harvested leaf (right); (B) Treatment process and sampling time points; (C) sucrose content; (D) MDA content; (E) Fv/Fm values; (F) REC values; (G) endogenous ABA content; (H) endogenous JA content; and (I) endogenous IAA content. Bars represent the mean ± SD (n = 3). Accumulation levels were analyzed using a T-test. Within each figure, asterisks above the bars indicate statistical significance (*p < 0.05; **p < 0.01)
