The Impact of Selenium Fertilization on the Quality Characteristics of Spring Wheat Grain

Abstract

Selenium is a micronutrient that is important for the proper functioning of the body. The research presented in this paper investigated the impact of various methods of selenium fertilization at various stages of plant growth on its content in grain and the quality properties of spring wheat (Triticum aestivum L.). Selenium fertilization did not affect the grain yield; however, it increased the selenium content in the grain. The research results showed that the accumulation of Se depends not only on the dose of the fertilizer but also on the stage of plant growth when the element is introduced. The most effective method of fertilization proved to be seed treatment and soil application combined with the foliar application at the tillering and stem elongation stages (G + S + F1-2), as well as at the stem elongation stage alone (G + S + F2). In terms of quality characteristics, the impact of selenium fertilization was observed only in the case of the falling number and the total protein content; all the parameters allowed for the grain to be classified as suitable for bread-making. Selenium fertilization can be considered as a safe way of increasing the Se content in spring wheat, which may contribute to an increase in the technological quality of the grain and its nutritional value.

Screening of Durum Wheat Cultivars for Selenium Response under Contrasting Environments, Based on Grain Yield and Quality Attributes

“…In our case, Se increased the protein content from 12.09 to 13.10% under semi-arid conditions and from 13.46 to 14.81% under sub-humid conditions. This is in line with the results of Radawiec et al [ 40 ] on spring wheat. The obtained values are indicators of good grain quality since the protein content that made satisfactory pasta or leavened bread should be at least ≥13% [ 50 ].…”

“…The obtained results (33.02 and 35.05 cm 3 under Kef–Boulifa and Beja conditions, respectively) meet the requirements of grain intended for baking purposes for this feature. According to Radawiec et al [ 40 ], Se supply did not affect the gluten content and Zeleny sedimentation index. Another relevant component of dough rheological properties is the deformation energy, predicting flour processing behavior and sufficient firmness of well-cooked semolina products [ 57 ].…”

“…According to Nawaz et al [ 39 ], Se foliar application promoted growth and yield of wheat and can reach 24%. However, Radawiec et al [ 40 ] depicted that Se fertilization did not affect the grain yield. This beneficial effect might be attributed to several indirect actions of Se.…”

Assessment of coherent impacts of selenium and urea on the growth and physiological attributes of wheat (Triticum aestivum L.)

“…Also [17] observed the similar foliar effects on the growth and physiochemical parameters in which selenium produced considerably positive impacts on the growth and physiology of plants. The conclusion of [18] about the foliar applications of selenium on brassica plants based on yield and productivity are also supporting the current findings under same environmental circumstances. The study of [19] about fertilization of selenium has confirmed the enhancing capacity of urea in which liquid fertilizer DAM-390 (30 kg of N/ha) significantly increased the growth of wheat plant.…”

Humic acid chelated selenium is suitable for wheat biofortification

“…Selenium source can be divided into inorganic selenium, organic selenium and nanoselenium, and their toxicity order is inorganic selenium > organic selenium > nanoselenium. Current studies have focused on inorganic selenium and nanoselenium with respect to seed selenium content and yield 9,11‐13 . Research on organic selenium is relatively scarce.…”
