Root and shoot dry matter (a,b), root and shoot phosphorus (P) concentration in dry matter (c,d), P translocation factor (shoot P/root P;e), P efficiency ratio (PER;f), a measure of P use efficiency calculated as Shoot Dry Matter/(Shoot P Concentration × Shoot Dry Matter), and root and shoot zinc (Zn) concentration in dry matter (g,h) of twoBrassica oleraceaaccessions (C6 and F103) grown hydroponically for two weeks in solutions containing 0.025 mM P (Low P; LP) and 0.25 mM P (High P;HP). Data are means (n= 18 for dry weight andn= 5–6 for concentrations, translocation factor and PER) and standard errors. Asterisks and different letters indicate statistically significant differences (two-way analysis of variance followed by Holm-Sidak post hoc test atP < 0.05)
