The aim of this work was determination of effects of growth regulators and their mixtures with magnesium sulphate on content and distribution of phosphorus in buckwheat plants. Growth regulators - benzylaminopurine (BAP), alpha-naphthylacetic acid (NAA), triacontanol (TRIA) and gibberellic acid (GA) - were applied to leaves, alone or in combinations with a 5 percent aqueous solution of magnesium sulphate. It was found that the growth regulators applied in the experiment (except BAP) caused a considerable increase in the phosphorus content of buckwheat leaves. A significant interaction was observed between BAP and TRIA with magnesium sulphate with respect to phosphorus concentration in stems and leaves in treatments with NAA, TRIA and GA, with magnesium sulphate
