高等植物对甲醇的释放和利用
Emission and utilization of methanol in higher plants
摘要
Abstract
Methanol, as one of the major volatile organic compounds (VOCs) found in the atmosphere, has been proved to be emitted from leaves of most plant species. The formation, emission and metabolism of methanol in higher plants were reviewed in this paper. Photosynthetic processes and chlorophyll a fluorescence parameters were measured on peony leaves treated with different methanol concentrations. The primary results revealed that photosynthesis was greatly improved by methanol, as indicated by higher photosynthetic rates and stomata conductance (GS). Strikingly different patterns were observed for photochemical quenching (qP), non-photochemical quenching (qN and NPQ), and electron transport rate (ETR). Decreases in Fm/Fo, Fv/Fo and φPSⅡ caused by methanol revealed dual effect of methanol (stimulation or inhibition) on the peony leaves, which were determined by the concentration of methanol and time duration. The data suggested that methanol can not only serve as carbon source, but also regulate energy distribution and dissipation, especially for non-photochemical quenching and photorespiration.关键词
