The effect of cytokinins with different chemical structures, adenine-type: N6-benzylaminopurine (BAP), N6-furfurylaminopurine (FAP) and derivative of urea - 1,3-diphenylurea (DPU) applied in optimal physiological concentrations of 10-6-10-4 M on the mixotrophic plant Wolffia arrhiza during the period of 20 days of culture, was examined. The cytokinin highest influence on the metabolites level in W...
Research on the influence of sex steroids: ß-estradiol, testosterone and corticosteroids: cortisone, cortisole (glucocorticoids), 11-deoxycorticosterone (mineralocorticoid) and prednisolone (chemical derivative of hydrocortisone) on changes of soluble proteins, nucleic acids and reducing sugars as a content of Wolffia arrhiza ( Lemnaceae ) has been conducted. Wolffia has been cultivated in Bialystok’s...
This paper presents the study concerning the influence of hydrocortisone and progesterone on the growth and the content of protein and sugar in the green alga Chlorella vulgaris Beijerinck (Chlorophyceae). Progesterone, at the concentration of 10-4 M, showed a lethal effect on C. vulgaris and hydrocortisone - at the concentration of 10-3 M. Hydrocortisone, in range of concentrations 5×10-5-10-4 M,...
Studies carried out on the alga Chlorella vulgaris (Chlorophyceae) showed that hydrocortisone applied in a concentration range of 10-4 - 10-5 M has a stimulating effect on its growth, i.e. the content of fresh and dry mass, and on the chlorophyll and carotenoid contents. Hydrocortisone was found to have its greatest stimulative effect on the biochemical parameters analysed in a concentration of 5x10-5...
