Mineral Composition of Organically Grown Wheat Genotypes: Contribution to Daily Minerals Intake

Abstract

In this study, 321 winter and spring wheat genotypes were analysed for twelve nutritionally important minerals (B, Cu, Fe, Se, Mg, Zn, Ca, Mn, Mo, P, S and K). Some of the genotypes used were from multiple locations and years, resulting in a total number of 493 samples. Investigated genotypes were divided into six genotype groups i.e., selections, old landraces, primitive wheat, spelt, old cultivars and cultivars. For some of the investigated minerals higher concentrations were observed in selections, primitive wheat, and old cultivars as compared to more modern wheat material, e.g., cultivars and spelt wheat. Location was found to have a significant effect on mineral concentration for all genotype groups, although for primitive wheat, genotype had a higher impact than location. Spring wheat was observed to have significantly higher values for B, Cu, Fe, Zn, Ca, S and K as compared to winter wheat. Higher levels of several minerals were observed in the present study, as compared to previous studies carried out in inorganic systems, indicating that organic conditions with suitable genotypes may enhance mineral concentration in wheat grain. This study also showed that a very high mineral concentration, close to daily requirements, can be produced by growing specific primitive wheat genotypes in an organic farming system. Thus, by selecting genotypes for further breeding, nutritional value of the wheat flour for human consumption can be improved.

Chemical Composition and Nutritional Value of Emmer Wheat (Triticum dicoccon Schrank): a Review

“…Minerals are divided into two groups: (i) macro minerals, which are needed in large amounts, e.g., calcium (Ca), magnesium (Mg) and potassium (K), etc., (ii) micro minerals or trace elements, which are required in smaller quantities, e.g., copper (Cu), zinc (Zn), iron (Fe), boron (B), selenium (Se) (Martinez-Ballesta et al, 2010). Due to the high consumption of emmer wheat in a variety of food products all over the world, emmer is considered an important source of minerals (Hussain et al, 2010).…”

“…Eredményeik új adatokkal gazdagítják a hazai adatbá-zist. A külföldi vizsgálatokban összehasonlították a bio-és az intenzív termesztéssel kapott eredményeket (HUSSAIN et al, 2010), vagy az eltérő ökológiai körzetekben termesztett fajtákat (ZHAO et al, 2009) vizsgálták, sőt még a klímaváltozás és a cink-és vashiány közötti összefüggéseket is közölték a C 3 -as és a pillangós növé-nyek esetén (MYERS et al, 2014). Ezek az eredmények is azt bizonyítják, hogy további vizsgálatokra van szükség.…”
