Other claims from this paper (13)
- Intervention effect Nickel alone reduced total shoot length by 22%.
- Intervention effect Selenium significantly improved shoot and root growth compared with nickel alone.
- Intervention effect Selenium decreased nickel accumulation in shoots and roots.
- Intervention effect Selenium partly alleviated nickel-induced decreases in shoot iron and magnesium concentrations.
- Intervention effect Nickel stress increased electrolyte leakage.
- Intervention effect Selenium diminished shoot electrolyte leakage under nickel stress.
- Intervention effect Nickel decreased chlorophyll a and b contents.
- Intervention effect Nickel increased the chlorophyll a/b ratio.
- Intervention effect Nickel did not affect carotenoid concentration.
- Intervention effect Selenium increased chlorophyll b content relative to nickel alone.
- Intervention effect Nickel decreased maximum quantum yield of photosystem II.
- Intervention effect Adding selenium improved photosystem II photochemical activity under nickel exposure.
- Mechanism The authors suggest that reduced nickel uptake may explain selenium protection.
