“…This was due to higher translocation of carbohydrates to sink, leading to higher grain filling and grain weight (Wahid et al, 2006) in filtered air. Picchi et al (2010) studied the potential risk of O 3 damage for modern wheat cultivars and found durum wheat to be more sensitive showing more severe symptoms than common aestivum wheat. However, in our study we observed that T. aestivum was more sensitive than T. durum with respect many yield parameters under EO.…”

“…With urbanization the demand for durum wheat is on the rise due to higher fast food consumption in India. Picchi et al (2010) studied the potential risk of O 3 damage for modern wheat cultivars; however, there are not many studies on the impact of elevated ozone levels on growth and productivity of T. durum species of wheat especially in the tropical region. Thus the present study was carried out to assess the impact of elevated ozone on growth, yield and nutritional quality of two wheat species grown in Northern India.…”

Sensitivity to tropospheric ozone is highly variable in cultivars of different plant species. Wheat, an important cereal crop, has been found to be sensitive to elevated ozone levels leading to differences in grain yields. The objective of this study was to compare the effects of elevated tropospheric ozone on growth, yield and nutritional quality of two species of wheat, Triticum aestivum (PBW 343) and Triticum durum (HD 2936), which are tropical wheat cultivars commonly grown in northern India. Experiments were conducted growing winter wheat (rabi season) under elevated tropospheric ozone in northern India for two years in open-top chambers (OTCs) under charcoal-filtered air (CF), non-filtered air (NF), open air (OA) and elevated ozone (EO) concentration (NF + 25-35 ppb O 3 ). There were different species responses to EO, with the modern aestivum wheat cultivar being more sensitive than durum wheat. The declines in all growth and yield parameters were greater in T. aestivum than T. durum in both the years. On average there was a 7% greater reduction in the photosynthetic rate and stomatal conductance in T. aestivum as compared to T. durum under EO at the flowering stage, and a 6% more reduction in leaf chlorophyll was observed on T. aestivum as compared to T. durum. Exposure to elevated O 3 caused a decrease in the number of leaves and leaf area index, rubisco enzyme activity and chlorophyll in both the species. More reductions in grain yield were observed in T. aestivum (15 and 19%) as compared to T. durum (9 and 13%) under EO in the two years, respectively. Filtration of air significantly increased all growth and yield parameters in both species of wheat.

“…Genetic differences among cultivars and varieties in ozone responses have mostly been studied for wheat and rice Picchi et al, 2010;Shi et al, 2009;Sawada et al, 2012). Recently, Tripathi and Agrawal (2012) reported that two cultivars of B. campestris responded differently to ozone (ambient + 10 ppb) in terms of yield, photosynthesis and oil content.…”

“…The physiological or genetic basis for the variation in O 3 sensitivity between genotypes is poorly understood (Fiscus et al 2005); however, the differences in O 3 sensitivity between the two cultivars cannot be attributed to differences in g s and thus to differences in O 3 uptake or flux. Moreover, there are examples where the O 3 response of grain yield did not necessarily correlate to the extent of leaf damage (Picchi et al 2010). The data presented in this manuscript indicate a need to test whether high-yield varieties such as Peg are particularly sensitive to O 3 exposure.…”

The adverse effects of tropospheric ozone (O 3 ) on crop photosynthesis, growth and yield have been documented in numerous studies over the last decades, but little information from field experimentation exists on how modern European winter wheat cultivars respond to O 3 . Two winter wheat cultivars (Astron and Pegassos) differing in development characteristics were exposed to non-filtered ambient air or non-filtered air plus 30 ppb and non-filtered air plus 60 ppb O 3 (8 h day À1 ) in open-top field chambers. At several dates during growth, green leaf area was determined by destructive harvests. Leaf gas exchange, pigment content and xanthophyll cycle activity, and photochemical efficiency by chlorophyll a fluorescence were measured. O 3 exposure induced accelerated senescence with no difference between cultivars. Photosynthesis declined especially in Pegassos; however, stomatal conductance was hardly affected by O 3 . Pigment contents were reduced by O 3 exposure, and de-epoxidation index increased. Photochemical efficiency (F v /F m ) declined, whereas actual quantum yield (Φ PSII ) did not respond to O 3 . O 3 exposure reduced grain yield in both cultivars. However, yield of Pegassos was more affected by O 3 exposure than yield of Astron, suggesting a higher O 3 sensitivity of Pegassos. The data presented in this manuscript indicate a need to test whether high-yield varieties such as Pegassos are particularly sensitive to O 3 exposure.
