Needles of Pinus halepensis as Biomonitors of Bioaerosol Emissions
We propose using the surface of pine trees needles to biomonitor the bioaerosol emissions at a composting plant. Measurements were based on 16S rRNA gene copy numbers of Saccharopolyspora rectivirgula, a bioindicator of composting plant emissions. A sampling plan was established based on 29 samples around the emission source. The abundance of 16S rRNA gene copies of S. rectivirgula per gram of ...
متن کاملPollution-Induced Histochemical and Chemical Adaptation in Pinus Needles from the Palermo Area (Italy)
We examined adaptations in histochemical composition and chemical element content in pine needles caused by pollution stress. Phenol content and trace element concentrations were measured in mature needles of Pinus halepensis Mill. and Pinus pinea L. from an urban ecosystem (the city of Palermo, Italy) and compared with samples collected in periurban sites where air pollution is presumably lowe...
متن کاملCharacterization of phenolic compounds in Pinus laricio needles and their responses to prescribed burnings.
Fire is a dominant ecological factor in Mediterranean-type ecosystems. Management strategies include prescribed (controlled) burning, which has been used in the management of several species, such as Pinus nigra ssp laricio var. Corsicana, a pine endemic to Corsica of great ecological and economic importance. The effects of prescribed burning on Pinus laricio have been little studied. The first...
متن کاملDetermination of Phenolic Compounds in Pinus eldarica by HPLC
Background: The antioxidant components have been identified in some pine species. Antioxidant properties of proantocyanidins reduce free radicals induced by DNA fragmentation and lipid proxidation and also proanthocyanidines could curb lipid peroxidation. Objective: In this study, we analyzed different parts of Pinus eldarica (bark, seed and needle) and assessed their antioxidant contents. ...
متن کاملAggregated Cones in Pinus Halepensis
Aggregated female cones were found in 192 Pinus halepensis trees growing in 54 populations in Israel, in habitats of vastly differing ecological conditions. All of these trees also carried normal (1-5 in a whorl) female cones. The number of aggregates per tree varied from one to several dozen. Some of the trees formed aggregates every year, after the first year of aggregate formation, while oth...
