Senescence parameters and respiration activities of harvested litchi fruit. (A) Disease index; (B) browning index; (C) proportion of edible fruits; (D) membrane permeability; (E) respiration intensity; (F) V
; and (G) ρV
. Data are the mean ± standard deviation (n = 3). An asterisk represents a significant difference (p < 0.05) between ATP-treated fruit and the untreated control.
