  • B concentrations were calculated based on root and shoot water content. Data are presented as means ± se (n = 4).

  • a Xylem concentrations were measured after 13 d of growth (n = 3).

  • b Yields in 5 mm B treatment were significantly (P < 0.05) lower than yields in low B nutrient solution.
