Other claims from this paper (11)
- Intervention effect Phosphorus up to the recommended rate enhanced rice growth by up to 35%.
- Intervention effect Silicon above 0.3 g Si kg−1 reduced rice growth.
- Intervention effect Photosynthetic rate was similar across P and Si treatments.
- Intervention effect Maximum PSII quantum yield was similar across P and Si treatments.
- Intervention effect Phosphorus increased shoot As concentration by up to 59% after P sufficiency.
- Intervention effect Silicon increased shoot As concentration by up to 28%.
- Intervention effect Silicon decreased shoot Cd concentration by up to 25%.
- Observation As accumulation rose tenfold from top to bottom leaves.
- Observation Cd accumulation rose 7.6-fold from top to bottom leaves.
- Recommendation The authors do not generally recommend P or Si for rice on soil contaminated by multiple heavy metals.
- Mechanism Rice plants were interpreted as efficiently translocating As and Cd to mature leaves.
