Table 2 Effect of salinity on shoot biomass, leaf growth, and mineral contents in the leaf growing zone

From: Effects of salinity on the transcriptome of growing maize leaf cells point at cell-age specificity in the involvement of the antioxidative response in cell growth restriction

  1. Effect of salinity on shoot biomass and leaf elongation rate (A), and on Relative elemental growth rate (REGR); % dry mater (DM), Na, Cl and Ca contents of growing leaf tissue from two locations along the growing zone: 15-30 mm and 30-50 mm from the leaf base (B). Plants were grown at 1mM NaCl (control) or 80 mM NaCl (Salt). Data are means ± SE (n=5).
