Other claims from this paper (12)
- Observation Drought had a rapid negative impact.
- Observation Salt stress had a more long-lasting effect.
- Intervention effect Drought and salt stress significantly decreased photosynthesis, transpiration and stomatal conductance.
- Intervention effect Drought and salt stress significantly decreased Fv/Fm and ΦPSII.
- Intervention effect Drought and salt stress increased nonphotochemical quenching.
- Association Under stress, PSII efficiency was strongly negatively correlated with xanthophyll pigment composition.
- Mechanism The authors infer nocturnal retention of zeaxanthin and antheraxanthin under stress.
- Intervention effect Salt stress inhibited leaf isoprene emission.
- Observation Isoprene emission responded less to stress than stomatal conductance and photosynthesis.
- Intervention effect Photosynthetic parameters fully recovered after rewatering and salt washing.
- Mechanism The authors infer that photosynthesis was downregulated rather than permanently impaired.
- Observation Sweetgum trees withstood and survived moderate drought and salt events without increasing isoprene emission.
