Other claims from this paper (6)
- Intervention effect Biomass, photosynthetic parameters and qp value of both cotyledons and true leaves of Ricinus communis seedlings decreased with increasing salt-alkali stress.
- Intervention effect Salt-alkali stress reduced photosynthetic pigments and ΦPSⅡ in cotyledons.
- Intervention effect Salt-alkali stress did not affect photosynthetic pigments and ΦPSⅡ in true leaves.
- Observation Fv/Fm and NPQ differed in trend between cotyledons and true leaves under salinity and alkalinity.
- Observation The authors conclude that alkali stress could cause much more damage to castor bean seedlings.
- Observation The authors conclude that cotyledons and true leaves show different physiological responses and adaptive strategies under salt-alkali stress.
