Figure 3 in Ionic homeostasis, biochemical components and yield of Italian zucchini under nitrogen forms and salt stress

Figure 3. Accumulation of sodium (Na+) (A), sodium/potassium ratio (Na+/K+) (B), sodium/calcium ratio (Na+/Ca++) (C and D) and sodium/ magnesium ratio (Na+/Mg++) (E and F) in Italian zucchini plants nourished with different forms of nitrogen and irrigated with saline waters. Means followed by different letters indicate significant difference by Tukey test at 0.05 probability level. * and ns - Significant at 0.05 probability level (p<0.05) and not significant (p>0.05), respectively.
