Title
Protective effect of divalent cations against aluminum toxicity in soybean
Ivo Ribeiro da Silva; Tarcísio Fernando Côrtes Corrêa; Roberto Ferreira Novais; et al. Revista Brasileira de Ciência do Solo 2008. doi:10.1590/s0100-06832008000500027
Other claims from this paper (9)
- Intervention effect Mn, Ba, Sr and Mg had positive or absent effects on soybean root elongation up to 100 µmol L-1.
- Intervention effect At 10 µmol L-1 aluminum, only Mg restored root growth to control levels.
- Intervention effect Higher tin doses slightly alleviated aluminum rhizotoxicity.
- Intervention effect Other cations reduced root growth or had no effect.
- Intervention effect Increasing exchangeable Ca:Mg ratio nearly doubled soybean shoot and root dry matter at constant soil pH.
- Mechanism Mg2+ alleviated aluminum toxicity more efficiently than Ca2+.
- Intervention effect CaCO3 increased soybean growth by increasing soil pH.
- Association Reduced aluminum toxicity coincided with lower aluminum accumulation in plant tissue.
- Mechanism The authors suggest Mg-induced absorption competition or exclusion explains lower tissue aluminum.
