| 中文摘要: |
| 为深入研究不同筋型小麦籽粒品质对地表臭氧（O3）浓度升高的响应，本研究依托于开放式O3浓度增加系统（O3-FACE），于2021年和2022年分别以13个（4个强筋品种、5个中筋品种、4个弱筋品种）和12个（4个强筋品种、6个中筋品种、2个弱筋品种）小麦（Triticum aestivum L.）品种为供试材料，设置环境O3浓度（AA）和1.5倍环境O3浓度（E-O3）处理，研究不同筋型小麦对O3浓度升高的响应差异。结果表明：O3浓度升高下2021年Ca元素含量显著升高24.8%，2022年直链淀粉含量显著降低8.1%。不同筋型小麦籽粒品质对O3响应存在显著差异，强筋和中筋小麦2022年直链淀粉含量显著降低8.6%和7.6%，2021年Ca元素含量显著升高 24.7% 和 27.2%，弱筋小麦 2021年淀粉含量显著降低 6.7%，两年蛋白质含量增幅较强筋和中筋小麦更大。根据不同筋型小麦籽粒品质标准，高浓度O3将会有利于中筋和强筋小麦品质形成，而不利于弱筋小麦籽粒品质形成。高浓度O3对所有供试小麦均有重要影响，其中宁麦13、扬麦33和扬麦22对O3敏感。 |
| 英文摘要: |
| To investigate the response of wheat grain quality with different gluten types to elevated tropospheric ozone（O3）, 13 wheat （Triticum aestivum L.）cultivars（4 strong-gluten varieties, 5 medium-gluten varieties, 4 weak-gluten varieties）in 2021 and 12 cultivars （4 strong-gluten varieties, 6 medium-gluten varieties, 2 weak-gluten varieties）in 2022 were grown in the Free-Air O3 Concentration Enrichment system（O3-FACE）. Two O3 treatments：ambient air（AA）and elevated O（3 1.5×ambient O3 concentration, E-O3）were used to study differences in the responses of wheat gluten types to elevated O3. The results showed that E-O3 significantly increased the Ca element content by 24.8% in 2021, and the amylose content significantly decreased by 8.1% in 2022. There were significant differences in the grain quality of different wheat gluten types in response to E-O3. Strong-and medium-gluten wheat showed a significant decrease of 8.6% and 7.6% in amylose content in 2022, while Ca element content increased significantly by 24.7% and 27.2% in 2021, respectively. Weakgluten wheat showed a significant decrease of 6.7% in starch content in 2021, with a larger increase in protein content over the past two years compared to medium-and strong-gluten wheat. According to the quality standards of wheat grains with different gluten types, E-O3 will be beneficial for the formation of grain quality in medium-and strong-gluten wheat, but is not conducive to the formation of grain quality in weak-gluten wheat. In summary, E-O3 has a significant impact on all tested wheat cultivars, in which Ningmai 13, Yangmai 33, and Yangmai 22 are sensitive to O3. |
