English. A number of physiological traits are proposed as selection criteria for drought tolerance. Physiological traits affected by drought can be correlated with the CO2 assimilation rate (Lal et al. 1996; Escalona et al. 1999; Lawlor and Cornic 2002; Guo et al. 2008; Robredo et al. 2010), PSII photochemical activity (Araus et al. 1998; Lu and Zhang 1999; Kocheva et al. 2005; Oukarroum et al. 2007; Kalaji et al. 2011; Jedmowski et al. 2013), leaf water conservation (stomatal conductance, transpiration rate, relative water content – RWC) (Chen et al. 2004; Bencze et al. 2011; Jedmowski et al. 2013) or plasma membrane integrity (Babu et al. 2004). The reliability of physiological and biochemical traits in the discrimination of drought susceptibility depends on species, genotypes (Kumar 2005; Praba et al.2009) and developmental stage (Szira et al. 2008).
