摘要: ABSTRACTDifferences between two maize and triticale genotypes grown in low soil compaction (LSC), moderate (MSC) severe (SSC) with a limited (D) or excess (W) water content were observed as decrease shoot (S) root (R) biomass, leaf greening (SPAD) increase membrane injury (LI), potential (ψ), photosynthesis (Pn), transpiration (E) stomata conductance (gS). Close correlations ψL ψR, differences ψR (Δψ) found. Drought waterlogging LSC conditions both resulted higher WUE than control plants (LSC C), but under the SSC declined. However, for WUE, treatments small insignificant. In general, changes markers greater sensitive to (Ankora, CHD-12) resistant ones (Tina, CHD-247) seedlings conditions.Abbreviations: ψL: l...
