Other claims from this paper (11)
- Intervention effect Increasing iron toxicity reduced rice germination rates.
- Intervention effect Increasing iron toxicity reduced seedling height and root length and number.
- Method / resource Relative seedling height and root length reductions at germination may better screen iron tolerance than other parameters.
- Intervention effect Plant height, tiller number and leaves rose slightly relative to controls until stated exposure days.
- Association Relative growth reduction grew with higher iron concentration.
- Association Relative growth reduction grew with longer exposure time.
- Observation After stress relief, plant height recovered by 3 – 12%.
- Observation After stress relief, tiller number recovered by 1-11%.
- Observation After stress relief, root number recovered by 7-19%.
- Observation Two cultivars differed significantly in relative growth and recovery changes.
- Method / resource The authors propose growth and recovery parameters as a simple screening method for iron-tolerant genotypes.
