Other claims from this paper (8)
- Observation In complete nutrient solution, rhizosphere pH around mature root cells of the Al-tolerant wheat cultivar Atlas 66 was slightly higher than in the bulk solution.
- Observation In CaSO4 solution, rhizosphere pH did not differ significantly between the wheat cultivars.
- Mechanism Rhizosphere pH of mature root tissue is not directly involved in the mechanism of differential Al tolerance in wheat.
- Intervention effect In Al-tolerant Atlas 66 grown with 5 micromolar Al, net K(+) influx, H(+) efflux and root-cell membrane potential in mature root tissue showed little change relative to the solution without Al.
- Intervention effect In Al-sensitive Scout treated with Al, K(+) influx was dramatically inhibited relative to the solution without Al.
- Intervention effect In Al-sensitive Scout treated with Al, H(+) efflux was moderately reduced relative to the solution without Al.
- Intervention effect In Al-sensitive Scout treated with Al, the membrane potential of mature root tissue depolarized relative to the solution without Al.
- Association Increased Al tolerance in wheat is associated with a greater ability of the tolerant plant to maintain normal ion fluxes and membrane potentials in root cells in the presence of Al.
