Other claims from this paper (17)
- Intervention effect In aluminium-free solution, calcium and ionic strength did not significantly alter subterranean clover root length.
- Intervention effect In aluminium-free solution, soybean roots were longer at 500 pM calcium than at higher calcium concentrations.
- Intervention effect Raising ionic strength at 500 and 5000 pM calcium significantly decreased soybean root length.
- Intervention effect With aluminium present, soybean root length was maximal at 15 000 pM calcium.
- Intervention effect With aluminium present, subterranean clover root length was maximal at 15 000 pM calcium.
- Intervention effect Soybean root length at 5000 pM calcium was 87% of that at 15000 pM calcium.
- Intervention effect Subterranean clover root length at 500 pM calcium was 53% of that at 15000 pM calcium.
- Intervention effect Subterranean clover root length at 5000 pM calcium was 81% of that at 15000 pM calcium.
- Intervention effect At 500 pM calcium with aluminium, increased ionic strength improved soybean root growth by 86%.
- Intervention effect At 500 pM calcium with aluminium, increased ionic strength improved subterranean clover root growth by 45%.
- Intervention effect At 5000 pM calcium, increased ionic strength benefited subterranean clover by 14%.
- Intervention effect Increasing solution calcium decreased water-extractable and acid-extractable aluminium in soybean roots.
- Intervention effect Increasing solution calcium decreased water-extractable and acid-extractable aluminium in subterranean clover roots.
- Intervention effect Soybean seedlings transferred to aluminium-free calcium solutions after aluminium exposure substantially recovered primary root growth.
- Intervention effect Recovered soybean relative root length was significantly higher at 5000 pM calcium than at 1500 or 500 pM.
- Observation Soybean roots transferred to 500 pM calcium after 6 or 18 hours of aluminium exposure accelerated elongation after a 30–40 hour lag.
- Intervention effect At 138 hours, soybean root length after 6 or 18 hours of aluminium stress was not significantly different from unstressed controls.
