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 کاملStudies on the structure of the plant wax nonacosan-10-ol, the main component of epicuticular wax conifers.
The main component presents in the epicuticular waxes of needles of Pinus halepensis and the most of conifers, the secondary alcohol nonacosan-10-ol, has been investigated by X-ray diffraction and differential scanning calorimetry. The results obtained from these physical techniques permitted to establish a definitive structural model of the molecular arrangement of this wax, basically in good ...
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...
متن کاملAllelopathic Effects of Pinus halepensis Needles on Turfgrasses and Biosensor Plants
Fresh, senesced, and decaying pine needles from Pinus halepensis were evaluated for their allelopathic potential on Festuca arundinacea, Cynodon dactylon and the biosensor plants Avena sativa and Lemna minor through in vivo and in vitro studies. The in vivo study was performed in growth chambers, using 6, 12, and 18 g of pine needle tissue mixed with screened perlite as a substrate. The effects...
متن کاملThe effect of (NH4)2HPO4 and (NH4)2SO4 on the spontaneous ignition properties of Pinus halepensis pine needles
The spontaneous ignitability of Pinus halepensis pine needles was evaluated. Fire points and times taken for irradiated fuels to be ignited were correlated, at given heat intensity, to the airflow around the specimen and the sample size. The tests showed that increase of the airflow rate above 1.5 lmin 1 increased considerably the fire point values and ignition delay times. On the contrary, the...
