这个博士后研究奖学金项目的重点是调查大气臭氧对生物挥发性有机化合物排放,叶蜡形态和植物生理学的影响。通过提高对臭氧暴露和植物损害背后的潜在机制的理解,可以提高预测臭氧空气污染对农作物影响的能力。本研究侧重于两个重叠的不确定性领域:大气臭氧(O3)污染如何影响植物生产力和植物生物挥发性有机化合物(BVOC)的排放。这项研究的目的是:(1)量化O3暴露对植物生理的影响,(2)确定O3暴露如何改变BVOC排放和植物生理的温度和二氧化碳(CO2)依赖性,(3)量化O3暴露对BVOC排放的影响,以及(4)确定植物从O3胁迫中恢复的能力。这项研究的更广泛的影响包括图书馆展览和针对4-6年级学生的教育研讨会。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
英文摘要
This Postdoctoral Research Fellowship project is focused on an investigation of the impact of atmospheric ozone on biogenic volatile organic compound emissions, leaf wax morphology, and plant physiology. By increasing the understanding of the underlying mechanisms behind ozone exposure and damage to plants, improvements can be made in the ability to predict impacts from ozone air pollution on crops.This research focuses on two overlapping areas of uncertainty: how atmospheric ozone (O3) pollution impacts both plant productivity and plant emissions of biogenic volatile organic compounds (BVOC). The objectives of this research are to: (1) quantify the impacts of O3 exposure on plant physiology, (2) identify how O3 exposure changes the temperature and the carbon dioxide (CO2) dependence of BVOC emissions and plant physiology, (3) quantify the impacts of O3 exposure on BVOC emissions, and (4) determine the ability of plants to recover from O3 stress.The broader impacts of this research include a library exhibit and workshops targeted toward educating students in grades 4-6. An educational pamphlet on ozone pollution will be created and made available to teachers and the public through web pages and the library.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
