Correlations between electrolyte leakage (EL) and three chlorophyll fluorescence parameters under two different drought−cold systems in
and ‘Muscat Hamburg’. (a)−(c): Correlation between EL and Fo
(b) and Fv/Fo
(c) under gradient cooling (GC) mode; (d)−(f): Correlation between EL and Fo
(e) and Fv/Fo
(f) under non−acclimated freezing (NAF) mode. Data were from those shown in Figures 2 and 3 as well as controls.
