ABSTRACT = {Mineral nutrient malnutrition, especially deficiency in selenium (Se),
affects the health of approximately 1 billion people worldwide. Wheat, a staple
food crop, plays an important role in producing Se-enriched foodstuffs to increase
the Se intake of humans. This study aimed to evaluate the effects of different Se
application methods on grain yield and nutritional quality, grain Se absorption and
accumulation, as well as 14 other trace elements concentrations in wheat grains.
A sand culture experiment was conducted via a completely randomized 3 × 2 × 1
factorial scheme (three Se levels × two methods of Se application, foliar or soil ×
one Se sources, selenite), with two wheat cultivars (Guizi No.1, Chinese Spring).
The results showed that both foliar Se and soil Se application methods had effects
on wheat pollination. Foliar Se application resulted in early flowering of wheat,
while soil Se application caused early flowering of wheat at low Se levels
(5 mg kg−1
) and delayed wheat flowering at high selenium levels (10 mg kg−1
),
respectively. For trace elements, human essential trace elements (Fe, Zn, Mn, Cu,
Cr, Mo, Co and Ni) concentrations in wheat grains were dependent of Se application methods and wheat cultivars. However, toxic trace elements (Cd, Pb, Hg, As,
Li and Al) concentrations can be decreased by both methods, indicating a possible
antagonistic effect. Moreover, both methods increased Se concentrations, and
improved grain yield and nutritional quality, while the foliar application was better than soil. Accordingly, this study provided useful information concerning
nutritional biofortification of wheat, indicating that it is feasible to apply Se to
conduct Se biofortification, inhibit the heavy metal elements concentrations and
improve yield and quality in crops, which caused human health benefits.},
