Correlation matrix using phenotypic mean values for recovery (REC), electrolyte leakage (EL) from leave and chlorophyll a fluorescence parameters. The parameters of JIP test were calculated and described as in Rapacz (2007): absorbed energy flux per leaf cross-section (CS) and the single, active PSII reaction center (RC) (ABS/CS, ABS/RC respectively); trapped energy flux in PSII reaction centers per leaf cross-section and the single, active PSII reaction center (Tr0/CS, Tr0/RC, respectively); the energy flux for electron transport per leaf cross-section and the single, active PSII reaction center (ET0/CS, ET0/RC, respectively); dissipation of energy in PSII reaction centers per leaf cross-section and the single, active PSII reaction center (DI0/CS, DI0/RC, respectively); yield of the energy trapping in PSII (Fv/Fm); performance indexes of PSII (PI) normalized for minimal and maximal densities of active reaction centers per leaf cross-section (PICS0 and PICSm, respectively); minimal and maximal densities of active reaction centers per leaf cross-section (RC/CS0 and RC/CSm, respectively); the quantum yield of electron transport (φEo); and the efficiency of the electron transfer from QA- to QB (ψo)
