Title

EFFECTS OF SIMULATED ACID RAIN STRESS ON GAS EXCHANGE AND CHLOROPHYLL A FLUORESCENCE PARAMETERS IN LEAVES OF LONGAN

Qiu Dong Acta Phytoecologica Sinica 2002

Other claims from this paper (11)

Intervention effect Acid rain inhibited photosynthesis and raised light compensation point.
Intervention effect Acid rain increased the light compensation point.
Intervention effect At pH 3.0, gas exchange and fluorescence parameters fell at 6 hours and recovered by 72 hours.
Intervention effect At pH 2.5, photosynthetic and fluorescence measures declined and failed to recover by 72 hours.
Intervention effect At pH 2.5, fluorescence decrease and quenching measures fell without recovery by 72 hours.
Intervention effect Intercellular CO2 fell at pH 2.5, then rose above control by 72 hours.
Intervention effect Acid rain increased dark respiration, which recovered at pH 3.0 but not pH 2.5.
Mechanism The authors infer restricted CO2 assimilation and proton-gradient establishment.
Mechanism The authors infer reduced photosynthetic electron transport and energy transformation efficiency.
Observation Nonphotochemical quenching was more sensitive to acid rain than photochemical quenching.
Recommendation Fv/F0 and qN are proposed as indicators of acid-rain damage in Longan.
