Abstract
În prezenta lucrare ne-am propus scopul de a testa acţiunea exopolizaharidelor izolate din Spirulina platensis şi modificate prin selenizare (Se-EPS) asupra unor procese din meristemele radiculare la plantele-test. Au fost studiate efectele diferitor concentraţii de Se-EPS (0,5, 1,0, 1,5 şi 2,0 mg/ml) asupra capacităţii germinative a seminţelor de ceapă şi asupra activităţii mitotice a celulelor meristematice radiculare. S-a constatat că soluţiile de Se-EPS, în concentraţiile utilizate, au un efect bioinhibitor asupra capacităţii germinative a seminţelor şi diviziunii mitotice a celulelor meristemelor radiculare. Extrapolarea acestor rezultate poate prezenta oportunităţi în prevenţia şi tratamentele terapeutice ale cancerului.
This paper aims to test the action of exopolyisaccharides isolated from Spirulina platensis and modified by selenization (Se-EPS) on processes from radicular meristems to test-plants. Effects of different concentrations of Se-EPS (0.5, 1.0, 1.5 and 2.0 mg / ml) on the germination capacity of onion seeds and on the mitotic activity of root meristematic cells were studied. It has been found that Se-EPS solutions in the concentrations used have a bioinhibitory effect on seed germination capacity and mitotic division of root meristematic cells. Extrapolation of these results may present opportunities in the prevention and therapeutic treatments of cancer.
