摘要：

We tested seven contemporary agrochemicals as potential plant protectants against ozone phytotoxicity. In nine experiments, Bel-W3 tobacco plants were experienced weekly exposures to a) 80 nmol mol(-1) of ozone-enriched or ozone-free air in controlled environment chambers, b) an urban air polluted area, and c) an agricultural-remote area. Ozone caused severe leaf injury, reduced chlorophylls' and total carotenoids' content, and negatively affected photosynthesis and stomatal conductance. Penconazole, (35% +/- 8) hexaconazole (28% +/- 5) and kresoxim-methyl (28% +/- 15) showed higher plants' protection (expressed as percentage; mean +/- s.e.) against ozone, although the latter exhibited a high variability. Azoxystrobin (21% +/- 15) showed lower protection efficacy and Benomyl (15% +/- 9) even lower. Trifloxystrobin (7% +/- 11) did not protect the plants at all. Acibenzolar-S-methyl + metalaxyl-M (Bion MX) (-6% +/- 17) exhibited the higher variability and contrasting results: in some experiments it showed some protection while in others it intensified the ozone injury by causing phytotoxic symptoms on leaves, even in control plants.
