In the temperate zone of Japan, Pinus densiflora Sieb. et Zucc. bears needles of up to three age classes in the upper crown and up to five age classes in the lower crown. To elucidate the effects of leaf age on photosynthetic parameters and its relationships with leaf mass per unit area (LMA) and leaf nitrogen (N(l)) concentration on an area (N(a)) and mass (N(m)) basis, we measured seasonal va...

The name Miconia densiflora Cogn. (1886) is a later homonym of Miconia densiflora (Gardner) Naudin (1851), but since we propose it as a taxonomic synonym of Miconia caudata (Bonpl.) DC. (1828), we do not provide a new name. The name Miconia longicuspisHerzog (1909) is a later homonym of Miconia longicuspis Cogn. (1891) and we here propose its replacement by Miconia longicuspidata S.S. Renner & ...

In this study, phenolic content of Pinus brutia’s bark was examined using an ultra-performance liquid chromatography tandem mass spectrometry with electrospray ionization source (UPLC-ESI-MS/MS) working in multiple reaction monitoring mode. Ultrasonic extraction method with 50% ethanol solution was used for the extraction of bark. The bark of Pinus brutia consisted of 15 compounds: gallic acid,...

Background and objective Particulate matter (PM) is the most dangerous form of air pollution, causes many diseases. Plants act as bio-filters to help reduce PM in atmosphere. also influences growth plants, so selecting suitable plant species for specific environmental conditions very important. The pollution tolerance index (APTI) was used determine level each pollution. purpose this study vari...

Aqueous fractionation of wood has been proposed as a suitable processing method for biorefineries. When treatments are performed under low severity conditions, water-soluble components (which could be detrimental in further processing stages) are removed, whereas polysaccharides, lignin, and other water-insoluble constituents remain in solid phase with little alteration. In order to explore the...
