Other claims from this paper (11)
- Intervention effect With MgSO4, high K (21 mM) significantly antagonized Mg uptake and reduced total Mg content in tomato.
- Intervention effect With MgSO4, high K (21 mM) negatively affected plant growth and root-to-shoot ratios at both Mg supply levels in tomato.
- Intervention effect The K3 (21 mM) treatment reduced total biomass by 45.35% compared with the K2 (7 mM) treatment in tomato.
- Intervention effect A high K supply combined with low Mg intake exacerbated Mg deficiency in tomato.
- Observation The optimal K:Mg ratio for tomato growth was 7:1.
- Mechanism K-Mg antagonism occurred mainly during root uptake, with excessive K leading to increased Mg2+ efflux in the root elongation zone of tomato.
- Intervention effect Mg(OH)2 nanoparticles alleviated K-induced Mg deficiency in tomato, shown by no significant correlation between K supply and relative Mg concentrations in nano-Mg-treated plants.
- Intervention effect With MgSO4, Mg concentration in tomato shoots decreased by 17.54% at K2.
- Intervention effect With MgSO4, Mg concentration in tomato shoots decreased by 35.63% at K3.
- Intervention effect With MgSO4, Mg concentration in tomato roots decreased by 27.72% at K2.
- Intervention effect With MgSO4, Mg concentration in tomato roots decreased by 37.08% at K3.
