“…The final pH of the solution was adjusted to 6.0. P was added to the solutions as NaH 2 PO 4 at three rates: 0.31, 3.1, and 31 mg P L -1 and Se was added as Na 2 SeO 3 at 0.1 mg Se L -1 ( Liu et al, 2004 ; Liu H. et al, 2010 ). Three times was replicated in each treatment.…”

Selenium (Se) is a necessary trace element for humans and animals, and Se fertilization is an efficient way to increase Se concentration in the edible parts of crops, thus enhance the beneficiary effects of Se in human and animal health. Due to the similarity of physical and chemical properties between phosphate () and selenite (), phosphorus (P) supply often significantly impacts the absorption of Se in plants, but little is known about how P supply influences the subcellular distribution and chemical forms of Se. In this study, the effects of P supply on subcellular distribution and chemical forms of Se in winter wheat were investigated in a hydroponic trial with medium Se level (0.1 mg Se L-1). P was applied with three concentrations (0.31, 3.1, and 31 mg P L-1) in the experiment. The results showed that increasing P supply significantly decreased the concentration and accumulation of Se in the roots, stems, and leaves of winter wheat. An increase in P supply significantly inhibited Se accumulation in the root cell wall, but enhanced Se distribution in the organelles and soluble fraction of root cells. These findings suggest that increased P supply inhibited the root-to-shoot transport of Se. An increase in P supply enhanced Se accumulation in the cell wall of plant stems (both apical and axillary stem) and cell organelles of plants leaves, but inhibited Se distribution in the soluble fraction of stems and leaves. This suggests that P supply enhances Se transportation across the cell membrane in shoots of winter wheat. In addition, increased P supply also altered the chemical forms of Se in tissues of winter wheat. These findings will help in understanding of the regulation grain Se accumulation and provide a practical way to enhance Se intake for humans inform Se-enriched grains.

“…In a hydroponic trial, added P increased Mo uptake in Brassica napus shoots, and improved Mo translocation from roots to shoots. 39 This can also partly explain why AM plants had higher Mo accumulation than non-AM plants: the AMF-increased soil available P may enhance more available Mo to release into soil solution absorbed by plants. However, Mo addition decreased P uptake in shoots, and in AM plant shoots, P uptake decreased with the increasing Mo addition levels ( Fig.…”

“…As one of the most important commercial and agricultural crops, oilseed rape is sensitive to Mo deficiency in soil, which affects its growth, production and seed quality. Liu et al (2010a) reported that the dry matter, chlorophyll concentration and net photosynthesis ratio (P n ) of seedling leaves were increased with supplying Mo in oilseed rape, but affected by different phosphorus (P) levels. Additionally, the yield of oilseed rape was obviously increased only in the presence of P fertilizer (Liu et al 2010b).…”

Molybdenum (Mo) is an essential element for higher plants. The objective of this study is to evaluate the effect of different Mo levels on the photosynthetic characteristics, yield and seed quality of two oilseed rape cultivars (ZS11 and L0917) using a pot experiment at four Mo levels [0 (control), 0.15, 0.3 and 1.0 mg kg −1 ]. Results showed that the dry matter significantly increased with Mo concentration increasing at the stem elongation stage. The net photosynthesis rate (P n), stomatal conductance (G s) and transpiration rate (T r) were the highest at the 0.15 mg kg −1 level but reduced at 0.3 and 1.0 mg kg −1 levels. The yield and harvest index were highest at 0.15 and 0.3 mg kg −1 for ZS11 and L0917, respectively. Gray correlation model analysis showed that the synthetic characteristics of seed quality (expressed as gray relation degree) followed the sequence of Mo1.0 > Mo 0 > Mo 0.3 > Mo 0.15 mg kg −1 for L0917 and Mo 1.0 > Mo 0.15 > Mo 0 > Mo 0.3 mg kg −1 for ZS11. Our results demonstrate that the yield of oilseed rape reached a maximum at 0.15 and 0.30 mg kg −1 for ZS11 and L0917, respectively, while the integrated seed quality is optimal at 1.0 mg kg −1 for both cultivars in Mo-deficient soil.
