Figure 4

Correlations between electrolyte leakage (EL) and three chlorophyll fluorescence parameters under two different drought−cold systems in V. amurensis and ‘Muscat Hamburg’. (a)(c): Correlation between EL and Fo (a), Fv/Fm (b) and Fv/Fo (c) under gradient cooling (GC) mode; (d)(f): Correlation between EL and Fo (d), Fv/Fm (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.
