Effects of selenium application on nutrient uptake and nutritional quality of Codonopsis lanceolata

Effects of foliar selenium application on growth and rhizospheric soil micro-ecological environment of Atractylodes macrocephala Koidz

“…Generally, Se often exerts a dual effect on plant growth ( Han et al., 2013 ; Hawrylak-Nowak et al., 2015 ; Zhu et al., 2017 ). In this experiment, Se potentially stimulated the growth of A. macrocephala at low levels but showed an inhibitory effect at high levels ( Table 1 ), which was consistent with the findings of previous studies on Nicotiana tabacum L. ( Han et al., 2013 , 2015 ), cucumber ( Hawrylak-Nowak et al., 2015 ) and Codonopsis lanceolata ( Zhu et al., 2017 ). The leaf area and the leaf width were significantly increased by 5.0 and 10.0 mg m −2 Se treatments, but under 20.0 mg m −2 Se level, the leaf area was significantly decreased ( Table 1 ), demonstrating the dual effects of Se on A. macrocephala growth.…”

“…The Se biofortification of plants was mainly applied on grain crops, fruits and vegetables, such as rice ( Deng et al., 2017 ), blueberry ( Li et al., 2018 ), tomato ( Zhu et al., 2018 ) and lentil ( Ekanayake et al., 2015 ), and only a few studies have been conducted on medicinal plants. Recently, Zhu et al. (2017) reported that the application of Se remarkably increased the polysaccharide and total flavonoid contents in Codonopsis lanceolata , which enhanced its health benefits for human beings.…”

“…Previous studies revealed that yield was the best index for evaluating growth state of plants ( Zhu et al., 2017 ). In this study, foliar Se application of ≤ 10.0 mg m −2 level increased the yield of A. macrocephala but decreased when Se level reached 20.0 mg m −2 ( Fig.…”

“…Previous studies revealed that Se application can affect the morphological, physiological and molecular characteristics of plants ( Ekanayake et al., 2015 ; Han et al., 2013 ; Schiavon and Pilon-Smits, 2017 ). Generally, Se often exerts a dual effect on plant growth ( Han et al., 2013 ; Hawrylak-Nowak et al., 2015 ; Zhu et al., 2017 ). In this experiment, Se potentially stimulated the growth of A. macrocephala at low levels but showed an inhibitory effect at high levels ( Table 1 ), which was consistent with the findings of previous studies on Nicotiana tabacum L.

Impact of Seedling Infection of Septoria Tritici Blotch on Bread Wheat

“…Application of Se fertilizer can increase the Se content in edible parts of plants. Moreover, Se contents generally improved with the increase of Se application rates (Zhu et al, 2017). In this experiment, both foliar Se and fertigated Se application methods significantly improved Se contents in sink-source organs (flag leaves, husks and grains) of 2 genotypes (Fig 1).…”
