Nutritive value and mineral composition of husked and naked spring wheat species in relation to cultivation technology

Abstrakt

The test material originated from a field experiment conducted in 2011–2013, at the Experimental Farm in Felin (51°22ʹ N, 22°64ʹ E), which belongs to the University if Life Sciences in Lublin. A two-factor experiment was conducted in randomised blocks with 4 replicates. The chemical composition of grain of 4 spring wheat species was analysed: common wheat (Triticum aestivum ssp. aestivum L.) cv. Parabola, durum wheat (Triticum durum Desf.) cv. SMH 87, spelt (Triticum aestivum ssp. spelta (L.) Thell.) cv. Blauer Samtiger, and emmer wheat (Triticum dicoccum (Schrank, Schubler) line PL 24062 (material acquired from the National Centre of the Plant Gene Pool), grown at different production technology intensity (medium and high level of cultivation technology). The analyses on wheat grain included the content of total protein, crude ash, crude fat, crude fibre, carbohydrates, phosphorus, potassium, magnesium, calcium, copper, iron, manganese and zinc. The results were subjected to an analysis of variance, while the differences were estimated by the Tukey’s test at the significance level of p = 0.05. The were calculated coefficients of variation (CV, %). Irrespective of the level of cultivation technology, husked wheats had higher quality parameters compared to naked cultivars. Emmer wheat was characterised by the highest content of proteins, ash, and macro and microelements in the grain and the spelt wheat cultivar Blauer Samtiger was characterised by the highest fat content. Compared to the husked species, the common wheat cultivar Parabola had the lowest content of proteins and ash, and a low content of macro and microelements. Both the husked and the naked wheats had better quality parameters in treatments with more intensive cultivation technology.
