“…In numerous studies, morphological and stress-related traits with agricultural importance were the main objective (Joergensen, 1992;Gunasekera et al, 1994;Ceccarelli & Grando, 1996;Forster et al, 1997;Lu et al, 1999;Ivandic et al, 2000Ivandic et al, , 2003Suprunova et al, 2004;Chen et al, 2004;Verhoeven et al, 2004a and b). The analysis of immediate stress responsive genes in accessions of H. spontaneum from different habitats demonstrated a strong correlation between genetic variability and adaptation to different environmental stress factors (Turpeinen et al, 2001(Turpeinen et al, , 2003Huang et al, 2002;Maestri et al, 2002;Suprunova et al, 2004). On the other hand, there is little information about the variation of physiological adaptations to different environmental stress factors.…”
