We studied the emission of [alpha]-pinene from Quercus ilex leaves. Only abaxial side hypostomatous Q. leaf emits [alpha]-pinene. Light induced photosynthesis and emission. However, response to dark-to-light transitions was faster than that [alpha]-pinene, suggesting ATP controls The higher at 30 20[deg]C, whereas did not change. Therefore, relationship between does always hold. When CO2 removed air, transpiration stimulated but were inhibited. [alpha]-Pinene inhibition more rapid under low...
The carbon of the four main monoterpenes emitted by Quercus ilex L. leaves was completely labeled with 13C after a 20-min feeding 99% 13CO2. This labeling time course is comparable isoprene, terpenoid other species and synthesized in leaf chloroplasts. It also that phosphoglyceric acid. Our experiment therefore provides evidence Q. are formed from photosynthesis intermediates may share same synthetic pathway isoprene. By analyzing rate distribution different fragments, we looked for...
The occurrence of 2‐nitrofluoranthene and 2‐nitropyrene in particulate matter collected urban, suburban, forest, remote areas located Europe, America, Asia, Antarctica was investigated. results obtained confirm the photochemical origin these components by gas phase reactions with OH radicals their ubiquitous troposphere. An important role formation dispersion seems to be played carbon particles.
Abstract A method has been developed for the collection and analysis of polar non‐polar C 4 ‐C 14 hydrocarbons involved in formation photochemical smog. Enrichment from both polluted unpolluted areas achieved with three‐stage traps packed carbon adsorbents different surface area; use a home‐made desorption unit employing cryofocusing then enables determination compounds by HRGC‐FID. Two‐stage filled graphitic have used prior to GC‐MS identification quantitation producing overlapping peaks....
Quercus ilex L. leaves emit terpenes but do not have specialized structures for terpene storage. We exploited this unique feature to investigate biosynthesis in intact of Q. ilex. Light induction allowed us distinguish three classes terpenes: (i) a rapidly induced class including alpha-pinene; (ii) more slowly class, cis-beta-ocimene; and (iii) the most 3-methyl-3-buten-1-ol. Using 13C, we found that alpha-pinene cis-beta-ocimene were labeled quickly almost completely while there was delay...
The algorithm developed by Guenther et al . [1991] to describe the organic emission of isoprene‐emitting plants has been used for predicting monoterpene from Quercus ilex L., an evergreen oak typical Mediterranean basin. dependence on photosynthetically active radiation and temperature verified through laboratory experiments carried out single leaves as well field measurements at branch level. While describes under stationary state conditions, it is less accurate when rapid fluctuations...
HRGC-MS has been used to identify and quantify volatile organic compounds (VOC) emitted during the combustion of biomass commonly burned in Mediterranean area summer. More than 200 components were identified quantified emissions. Data obtained can be useful model impact that forest fires some agricultural practices might have on tropospheric ozone formation acid deposition.
