e0“The addition of Si significantly (P < 0.05) reduced root length, dry weight, shoot nitrogen (N) and phosphorus (P) concentration, root N and potassium (K) concentration, and increased root P concentration of barley plants exposed to 75 μmol L−1 Al and above.”

Other claims from this paper (14)
- Intervention effect Aluminum increased plasma membrane permeability, and silicon did not alleviate it.
- Intervention effect Silicon reduced root length in barley exposed to at least 75 μmol L−1 Al.
- Intervention effect Silicon reduced dry weight in barley exposed to at least 75 μmol L−1 Al.
- Intervention effect Silicon reduced shoot nitrogen (N) in barley exposed to at least 75 μmol L−1 Al.
- Intervention effect Silicon reduced phosphorus (P) concentration in barley exposed to at least 75 μmol L−1 Al.
- Intervention effect Silicon reduced root N in barley exposed to at least 75 μmol L−1 Al.
- Intervention effect Silicon reduced potassium (K) concentration in barley exposed to at least 75 μmol L−1 Al.
- Intervention effect Aluminum at 75 μmol L−1 or above inhibited barley nutrient uptake regardless of silicon.
- Intervention effect Silicon alleviated aluminum effects on barley growth at 50 μmol L−1 Al.
- Intervention effect At 50 μmol L−1 Al with silicon, dry matter weight differed little from aluminum-deprived barley.
- Intervention effect At 50 μmol L−1 Al with silicon, nutrient uptake differed little from aluminum-deprived barley.
- Intervention effect Under aluminum stress, increasing silicon increased barley shoot aluminum concentration.
- Intervention effect Increasing aluminum decreased barley shoot silicon concentration.
- Mechanism The authors attributed silicon-enhanced aluminum toxicity partly to mineral nutrient imbalances.
