Growth parameters [dry weight (DW, mg) and length (cm)], total boron concentration ([B_t], μg g^-1 DW) and total B content (B_t, μg) measured in roots, stems and leaves of <i>Citrus macrophylla</i> seedlings grown for 25 days in B-normal (50 μM, Ct) and B-toxic (400 μM, +B) nutrient solutions.

1Values of DW and length are the means ± SE of six independent plants per treatment (n = 6). 2Values of [Bt] and Bt are the means ± SE of three independent experiments (n = 3). For a comparison of means, an ANOVA followed by the LSD test, calculated at the 95% confidence level, was performed. Different letters indicate significant differences for each parameter and within each plant organ (P <0.05).
