(1) The growth of Lavatera arborea was investigated in sand culture by subjecting the seedlings to three salinity and phosphate treatments in a 3 × 3 factorial design. (2) Additional phosphate enhanced growth in non-saline and saline conditions, but growth was most in 40% sea water with additional phosphate. (3) The limit of salt tolerance of this species without additional phosphate was about 50% sea water but the limit was increased with additional phosphate. (4) Phosphate enhanced root growth at high salinity and resulted in increased potassium, calcium, magnesium and phosphorus contents in the shoot. (5) The results are discussed in relation to the halophytic nature and the salt tolerance of the species.
