title: [Effects of elevated ozone concentration on wheat grain protein components with FACE system].
abstract: In 2006-2009, a Free-Air Controlled Enrichment (FACE) system was applied to study the effects of elevated ozone concentration ([O3]) on the grain protein components and their dynamics of four winter wheat varieties Yannong 19, Yangmai 16, Yangmai 15, and Yangfumai 2. Two levels of [O3] were installed, i. e., ambient level (CK-O3) and 50% higher than the ambient level (E-O3). With the increase of [O3], the grain protein content of the varieties increased, with the increment being 7.55% - 16.37% (2006 - 2007), 4.93% - 22.63% (2007 - 2008), and 2.29% - 17.65% (2008 - 2009) in the three years, respectively, and the differences between treatments, varieties, and years being all significant. Adversely, the grain protein yield was decreased significantly by 1.83% - 11.64% (2006 - 2007), - 0.41% - 24.22% (2007 - 2008), and -1.90% - 15.81% (2008 - 2009), respectively in the three years. The contents of four grain protein components (albumin, globulin, gliadin, and glutenin) were significantly higher under E-O3 than under CK-O3, and the differences between treatments, varieties, and years were significant, except the albumin and glutenin contents between treatments.
