Fagopyrin and rutin concentration in seeds of common buckwheat plants treated with Se and I / Vsebnost fagopirina in rutina v semenih navadne ajde tretirane s selenom in jodom
Very little data about impact of simultaneous addition of selenium and iodine on plants exists. Plants of common buckwheat Fagopyrum esculentum Moench. were grown outdoors and were foliarly treated at the beginning of the flowering with different forms of Se (selenite, selenate) and I (iodide, iodate) and their combinations. Plants were harvested and seeds were collected and grounded, and the concentrations of fagopyrin and rutin were determined. Nor Se, nor I, alone or their combination had an influence on the concentration of fagopyrin. Selenium, iodine and their combination affected the amount of rutin in common buckwheat grain.
Key words: fagopyrin, rutin, common buckwheat, seeds, Se, I
Zelo malo je znanega o sočasnem vplivu elementov selena in joda na rastline. Rastline navadne ajde (Fagopyrum esculentum Moench.) gojene na prostem, smo v začetku cvetenja tretirali z raztopinami selena (selenit, selenat) in joda (jodit, jodat) ter njihovimi kombinacijami. Zrnje tretiranih rastlin je bilo zmleto in izmerili smo koncentracije fagopirina in rutina. Na koncentracijo fagopirina v zrnju ni vplivalo niti tretiranje rastlin s selenom niti z jodom, pa tudi ne kombinacija obeh elementov. Na koncentracijo rutina v zrnju pa so značilno vplivala tako posamična tretiranja z raztopinami obeh elementov kot tudi kombinirano tretiranje.
