    The Nutrient Content in Soybean Seeds (Glycine Max L. Merr.) After Application of Exogenous Growth Regulators
    (Wydawnictwo Uczelniane Zachodniopomorskiego Uniwersytetu Technologicznego w Szczecinie, 2015) Nowak, Anna; Wróbel, Jacek; Laboratory of Dermatological Pharmacotherapy, Pomeranian Medical University, Szczecin, Poland; Department of Plant Physiology and Biochemistry, West Pomeranian University of Technology, Szczecin, Poland
    A two-year pot experiment was carried out at the Experimental Hall, West Pomeranian University of Technology in Szczecin. The experiment examined the effect of exogenous growth regulators, i.e. indolilo-3-butyric acid (IBA) and 6-benzylaminopurine (BAP) used separately and in a mixture, on the content of nutritionally valuable macronutrients (Na, K, Ca, P and Mg) and sulphur amino acids (methionine and cysteine) in the seeds of three Polish soybean (Glycine max L. Merr.) cultivars, i.e. Aldana, Progres and Jutro. During plant vegetation, double spraying with growth regulators at a concentration of 30 mg · dm–3 was applied. Plants from the Jutro cultivar sprayed with 6-benzylaminopurine (BAP) were characterized by the highest content of Na, K, Ca and Mg and sulphur amino acids but also the lowest content of nitrates. Other variants of growth regulators also had a positive effect on the improvement of qualitative traits in the soybean cultivars examined but to a lesser extent. Growth regulators significantly but variably influenced the nutritional content of macronutrients in the seeds of three soybean cultivars. The content of calcium, potassium and magnesium increased regardless of the type of growth regulators. On the other hand, a decrease in the nitrate form of nitrogen content was observed. BAP significantly increased the content of nutritionally valuable elements such as calcium and magnesium, and essential amino acids, especially in the Jutro and Progres cultivars. The results indicate a positive effect of growth regulators on the biological value of the tested cultivars of soybean seeds.
