ABSTRACT
Selenium (Se) is essential for human beings and animals and can be beneficial to plants. Wheat is a staple crop with the capacity to accumulate Se. Nitrogen (N) is essential for wheat growth and development and is closely related to wheat yield and quality. N contents in different wheat organs increased with the increase of N application rate under the same Se treatment. Similarly, wheat Se content increased with an increase of Se application rate in both years when exposed to the same N treatment. Interactions between Se and N applications on their respective contents were observed. With an increase of N application, the average Se content in organs initially increased and then decreased, suggesting that Se accumulation was N-dependent. The moderate N application promoted the uptake of Se, whereas high N dosage application inhibited Se accumulation.
