“…found that reduced photosynthetic electron transfer in photosystem II (Fv/Fm) occurred in the sepals under elevated [O 3 ] (Keutgen & Pawelzik, ), but no further work has been done investigating direct O 3 uptake by sepals or other floral organs. Exposure of flowers to elevated [O 3 ] can lead to increased flower abortion (Feder, ; Black et al ., ; Fernandez‐Bayon et al ., ; Findley et al ., ), which can negatively affect seed set, fruit number and fruit weight, even in the absence of visible foliar injury (Black et al ., ). Our meta‐analysis and other literature suggests that an increase in flower abortion at elevated [O 3 ] may be dose‐dependent and/or species dependent.…”

“…Our meta‐analysis and other literature suggests that an increase in flower abortion at elevated [O 3 ] may be dose‐dependent and/or species dependent. For example, flower number was decreased in carnation (Feder & Campbell, ; Feder, ), Lemna perpusilla (Feder & Sullivan, 1969b), Brassica napus (Black et al ., ), Citrillus lanatus and Cucumis melo (Fernandez‐Bayon et al ., ) under elevated [O 3 ], whereas studies done on Lycopersicon esculentum (Oshima et al ., ), Plantago major (Reiling & Davison, ), Phaseolus vulgaris (Kohut et al ., ) and Prunus salicina (Retzlaff et al ., ) all reported an increase in flower number under elevated [O 3 ]. Certainly, more studies of the effects of elevated [O 3 ] on flower initiation and abortion are needed to understand the mechanisms by which O 3 alters flower development.…”

Tropospheric ozone (O 3 ) is a harmful air pollutant that can negatively impact plant growth and development. Current O 3 concentrations ([O 3 ]) decrease forest productivity and crop yields and future [O 3 ] will likely increase if current emission rates continue. However, the specific effects of elevated [O 3 ] on reproductive development, a critical stage in the plant's lifecycle, have not been quantitatively reviewed. Data from 128 peer-reviewed articles published from 1968 to 2010 describing the effects of O 3 on reproductive growth and development were analysed using metaanalytic techniques. Studies were categorized based on experimental conditions, photosynthetic type, lifecycle, growth habit and flowering class. Current ambient [O 3 ] significantly decreased seed number (À16%), fruit number (À9%) and fruit weight (À22%) compared to charcoal-filtered air. In addition, pollen germination and tube growth were decreased by elevated [O 3 ] compared to charcoal-filtered air. Relative to ambient air, fumigation with [O 3 ] between 70 and 100 ppb decreased yield by 27% and individual seed weight by 18%. Reproductive development of both C 3 and C 4 plants was sensitive to elevated [O 3 ], and lifecycle, flowering class and reproductive growth habit did not significantly affect a plant's response to elevated [O 3 ] for many components of reproductive development. However, elevated [O 3 ] decreased fruit weight and fruit number significantly in indeterminate plants, and had no effect on these parameters in determinate plants. While gaps in knowledge remain about the effects of O 3 on plants with different growth habits, reproductive strategies and photosynthetic types, the evidence strongly suggests that detrimental effects of O 3 on reproductive growth and development are compromising current crop yields and the fitness of native plant species.

“…3). The sensitivity to ozone varied between racemes, with the losses of reproductive sites being greatest in the second and third lateral racemes (Bosac, 1992 ;Black et al, 1993). However, although ozone-treated plants of both cultivars exhibited greater losses of fertile sites up to 25 d after exposure, the number present at final harvest was not significantly different from control plants, demonstrating that oilseed rape is capable of compensating for ozone-induced losses of fertile sites during flowering (Bosac et al, 1994).…”

Sexual reproductive development is a crucial stage in the life cycle of higher plants as any impairment of the processes involved might have significant implications for the productivity of crop plants and the survival of native species. There is considerable evidence that exposure to ozone, even at current ambient levels in many industrialized countries, reduces grain and fruit yields and adversely affects yield quality. It is also well established that sensitivity to ozone may differ not only between species, but also between cultivars and populations of individual species, and that the impact of exposure is highly dependent on ozone concentration and the duration and timing of exposure. However, few studies have attempted to distinguish between the direct effects of air pollutants on reproductive development, and indirect effects mediated by injury to the vegetative organs and associated changes in the supply of assimilates and other essential resources to support reproductive growth, or the levels of endogenous growth regulators. This review considers the impact of ozone on the reproductive biology of agricultural and native species, and examines its direct effects on specific reproductive processes. The extent to which compensatory responses redress the adverse effects of exposure is also explored, with particular reference to recent studies of Brassica napus (oilseed rape), Brassica campestris (Wisconsin Fast Plants), Plantago major (greater plantain) and Triticum aestivum (wheat).
