| Abstract: | "Tropospheric ozone (O(3)) affects isoprenoid emissions, and floral emissions in particular, which may result in potential impacts on the interactions of plants with other organisms. The effects of ozone (O(3)) on isoprenoid emissions have been investigated for many years, while knowledge on O(3) effects on floral emissions is still scarce and the relevant mechanism has not been clarified so far. We investigated the effects of O(3) on floral and foliar isoprenoid emissions (mainly isoprene, monoterpenes and sesquiterpenes) and their synthase substrates from three rose varieties (CH, Rosa chinensis Jacq. var. chinensis; SA, R. hybrida 'Saiun'; MO, R. hybrida 'Monica Bellucci') at different exposure durations. Results indicated that the O(3)-induced stimulation after short-term exposure (35 days after the beginning of O(3) exposure) was significant only for sesquiterpene emissions from flowers, while long-term O(3) exposure (90 days after the beginning of O(3) exposure) significantly decreased both foliar and floral monoterpene and sesquiterpene emissions. In addition, the observed decline of emissions under long-term O(3) exposure resulted from the limitation of synthase substrates, and the responses of emissions and substrates varied among varieties, with the greatest variation in the O(3)-sensitive variety. These findings provide important insights on plant isoprenoid emissions and species selection for landscaping, especially in areas with high O(3) concentration" |
