Abstract
Growth regulators: 3-indolebutyric acid (IBA), alpha-naphthylacetic acid (NAA), triacontanol (TRIA), benzylaminopurine (BAP) and gibberellic acid (GA3) were applied as foliar fertilizers, alone or in combinations with a 5 percent aqueous solution of magnesium sulphate, twice in the growing season of spring triticale - at the stage of earing and right before flowering. In the first year of the experiment the growth regulators applied with magnesium sulphate caused a significant stem elongation. An interaction was also found between growth regulators and magnesium sulphate (a significant increase in thousand grain weight under the influence of NAA + Mg, and a significant decrease in thousand grain weight in triticale under the influence of triacontanol and benzylaminopurine + magnesium sulphate). In the second and third year of the experiment some growth regulators (NAA, IBA and GA3) caused a significant increase in the total aboveground weight of triticale plants. Means of three years indicate a significant increase in grain weight caused by IBA and GA3 applied in combinations with magnesium sulphate. Most of the growth regulators used in the study, especially when applied together with magnesium sulphate, increased the proportion of grain in the total aboveground weight of spring triticale plants
