Figures & Tables

Figure 1

Effects of nutrient deficiency on the shoot macronutrient concentrations in BA and AL seedlings. Different letters indicate statistically significant difference between means (p < 0.05). –N, –P and –K indicate media without N, P and K, respectively. AL, Alook (Prunus scoparia L.); BA, bitter almond (Prunus dulcis L.).
