Soil carbon dioxide fluxes in natural and CO2-enriched systems
Carbon dioxide fluxes between the soil and atmosphere were determined on the 1991 free-air carbon dioxide enrichment (FACE) experiment at the Maricopa Agricultural Center, Maricopa, Arizona. The study was conducted on drip-irrigated cotton in conjunction with other physical and physiological measurements. Fluxes were measured with a 1.6 1 closedchamber static sampling system. The main treatment...
متن کاملRunning title: Multi-locus polymorphism in Populus tremula Keywords: demography, linkage disequilibrium, nucleotide polymorphism, Populus tremula Multilocus patterns of nucleotide polymorphism and the demographic history of Populus tremula
I have studied nucleotide polymorphism and linkage disequilibrium using multilocus data from 77 fragments, with an average length of fragments 550 bp, in the deciduous tree Populus tremula (Salicaceae). The frequency spectrum across loci showed a modest excess of mutations segregating at low frequency and a marked excess of high frequency derived mutations at silent sites, relative to neutral e...
متن کاملElevated CO2 and/or ozone modify lignification in the wood of poplars (Populus tremula x alba)
Trees will have to cope with increasing levels of CO(2) and ozone in the atmosphere. The purpose of this work was to assess whether the lignification process could be altered in the wood of poplars under elevated CO(2) and/or ozone. Young poplars were exposed either to charcoal-filtered air (control), to elevated CO(2) (800 μl l(-1)), to ozone (200 nl l(-1)) or to a combination of elevated CO(2...
متن کاملA novel antioxidant phenyl disaccharide from Populus tremula knotwood.
The complete characterization of two compounds obtained from the acetone extract of Populus tremula knotwood has been was achieved using LC-DAD-MS, MS/MS, IR and NMR. The new compounds were unequivocally identified as a mixture of the ester isomers of the (E) and (Z) p-coumarate of 1-O-rutinose. The isomers showed the capacity to inhibit lipid peroxidation induced by tert-butylhydroperoxide and...
متن کامل20-(Z)-Cinnamoylsalicortin: A novel salicinoid isolated from Populus tremula
Using a combination of NMR and mass spectroscopic techniques, we have isolated a new salicinoid from the foliage of European aspen (Populus tremula) and identified it as 20-(Z)-cinnamoylsalicortin. The relatively high amounts in foliage and the similarity in structure to bioactive salicinoids isolated from other salicaceous trees indicates that this compound may have implications for the study ...
