Significance for science
Novelty of present research and important for the scientific word are especially findings about the effect of Se on aquatic plants and metabolism of Se in crop plants and plants grown in natural environment. Data about the effect of Se on aquatic plants and especially about the metabolism of Se in aquatic plants are first in Slovenia and scarce also in international level.
Results showed on differences in Se metabolism between selected crops and aquatic plants. Cabbage and red cabbage transformed applied inorganic form - Se(VI) into SeMet. Myriophyllum spicatum and Ceratophyllum demersum, treated with Se(VI), accumulated Se in the form of Se(VI). M. spicatum, C. demersum and Potamogeton perfoliatus transformed added Se(IV) to SeMeSeCys and SeMet. Aquatic moss Fontinalis antipyretica accumulated Se in inorganic forms only. All investigated species accumulated high amount of Se, therefore they can be used for phytoremediation of Se. This research demonstrates an impact of Se in Tartary buckwheat on the progeny plants of Se sprayed plants. Se affected physiological characteristics of Se-treated progeny plants. Se substances were involved in epigenetic changes.
It was found out how we can achieve optimal concentration od Se in plants, used for food and which Se species accumulated in edible parts of the treated plants.
Significance for the country
Se is added to feedstuff and fertilizers from where it is spilled to the environment. We found out that concentration of Se in waste waters from animal farms was higher comparing to water in watercourses. Aquatic plants, grown in watercourses that flow through agricultural environment had higher concentration of Se comparing to plants, grown in watercourses flowing in more pristine areas. Selected aquatic plants in rivers can be used for biomonitoring of Se, that is especially true for aquatic moss Fontinalis antipyretica. All investigated species accumulated high amount of Se, therefore they can be used for phytoremediation of Se.
100g of Se treated cabbage contained 44 µg Se. Thus, Se treated plants can be used as food supplements. Broccoli sprouts, grown from Se treated seed can be used as functional food.
In the case of Tartary buckwheat sprouts, grown after soaking in the Se solution with 30 mgSe(VI)/L in greenhouse, the European recommended daily doses would be covered by consuming about 10.7 to 25.0 g of fresh sprouts daily, or in the case of USA recommendation about 19.6 g. Se fortified Tartary buckwheat sprouts have possibility as functional food and/or food supplement because of suitable content of Se and high flavonoid content.
The large proportion of the soluble Se in Se-enriched Tartary buckwheat seeds was in the form of SeMet, which is known to be the major nutritional source of Se for animals and it is highly bioavailable. All those indicate that Se-enriched buckwheat is a potential source of dietary Se for animals and humans. Our outcomes can be the basis for the development of new functional products.
