摘要
The effects of simulated acid rain (SAR) on the photochemistry, net photosynthesis (Pn), morphological damage, and crop yield were studied on Vaccinium angustifolium Ait. Although there was an 8% decrease in fluorescence origin with the pH 1.5 SAR treatment when compared to the control, no effects on the quantum efficiency of photosystem II (PSII) photochemistry, Pn, leaf and berry wax deposition were detected. There was no SAR effect on crop yield or the physiological components studied.
