“…3). Such linear irradiance responses have been previously reported for Vicia faba and Platanus acerfolia (Seiler and Giehl, 1977), Oryza sativa (Yonemura et al, 1999), and Sequoiadendron gigantum (Derendorp et al, 2011).…”

“…In darkness, the mean temperature response of the emission of the two plant species resulted in α = 11 nmol CO m −2 h −1 and a temperature sensitivity β = 0.104. Thus, the mean temperature sensitivity under UV-B is so low that it indicates an abiotic process (Derendorp et al, 2011). In darkness, however, the temperature sensitivity for the green leaves resembled the activation energy associated with biological processes.…”

“…The exact nature of the origin of the produced CO in fresh leaves remains unclear, but it may be cellulose. UV-induced emission rates of CO from dead plant material have been observed to be oxygen dependent in several studies (Tarr et al, 1995;Yonemura et al, 1999;Derendorp et al, 2011). In studies on green lima bean leaves, Tarr et al (1995) Biogeosciences , indicated that the photo-production of CO occurred inside the leaves.…”

“…However, we did measure the CO emission of dried material (litter), and found, as others (Tarr et al, 1995;Yonemura et al, 1999;Derendorp et al, 2011), that the CO emission is about one order of magnitude larger in dried leaves compared to that of fresh leaves. Hence, more knowledge is also needed in order to evaluate how a higher degree of leaf desiccation may increase rates of CO emission.…”

“…However, in the studies underlying the photo-induced CO emission by living plants, which were incorporated into previous global CO budgets (IPCC 1995(IPCC , 2001, the UV component of (sun)light was not considered (Seiler and Giehl 1977;Seiler et al, 1978). In studies of photochemically induced release of CO by dead plant material, it was demonstrated that the more energy-rich UV light had a very significant impact on the total CO emission (Tarr et al, 1995;Schade et al, 1999a;Derendorp et al, 2011). The aim of this study was thus to examine the potential of UVinduced CO emission from living plants in relation to plant species and environmental conditions.…”

Abstract. The global burden of carbon monoxide (CO) is rather uncertain. In this paper we address the potential for UV-induced CO emission by living terrestrial vegetation surfaces. Real-time measurements of CO concentrations were made with a cavity-enhanced laser spectrometer connected in closed loop to either a chamber on a field of grass or a plant-leaf scale chamber. Leaves of all plant species that were examined exhibited emission of CO in response to artificial UV radiation as well as the UV component of natural solar radiation. The UV-induced rate of CO emission exhibited a low dependence on temperature, indicating an abiotic process. The emission of CO in response to the UV component of natural solar radiation was also evident at the natural grassland scale.

11During the past few decades it has been documented that the ultra-violet (UV) component of natural 12 sunlight alone or in combination with visible light can instantaneously stimulate aerobic plant production of 13 a range of important trace gases: CH 4 , CO 2 , CO, short-chain hydrocarbons/ non-methane volatile organic 14 compounds (NMVOC), NO x and N 2 O. This gas production, near or at the plant surface, is a new discovery 15 and is normally not included in emission budgets (e.g. by the Intergovernmental Panel on Climate Change, 16 IPCC) due to a lack of information with respect to validation and upscaling. For CH 4 it is known that the light 17 dose controls emission under ambient and artificial light conditions, but the atmospheric gas composition 18 and other environmental factors can influence gas production as well. Several plant components, including 19 pectin and leaf wax, have been suggested as a precursor for CH 4 , which equals 7-24% 28 of the natural terrestrial source strength accounted for ). In this review, we 29 summarize current knowledge, based on experimental work with sunlight and artificial light, and estimate 30 potential emission ranges and uncertainties, placing the available data into perspective. We discuss the 31 state of the art in proposed mechanisms, precursors, and environmental relationships, we consider the 32 relevance of measured emission rates, and we also suggest a range of future research topics. Furthermore 33 we propose and describe methods and techniques that can be used for future research. 34
