Premise The objective of this study was to optimize an existing DNA extraction protocol for recalcitrant plant taxa obtain high-quality from preserved herbarium tissue suitable downstream PCR applications. Methods and Results Leaf 30 diverse species obtained the U.S. National Arboretum Herbarium. Our previous (Gouker et al., 2020, Applications in Plant Sciences 8: e11403) improved by use 10X Tr...
Q. mongolica forests are representative forest types in Korea, belonging to the intermediate succession stage with highest species diversity. Identifying community structure and growth rate of by vegetation climate zone can help planning efficient restoration strategies for each zone. The proportions major communities based on zones newly adjusted Korea National Arboretum 2020 were determined. ...
Abstract—Geometrical shape of bamboo usually assumed as tapered hollow pipe. This study proved that the dimensional changes along the bamboo stem significantly affected to its Modulus of Rupture (SR) value which measured from third point loading bending test. Therefore if the bending test applied using third point loading configuration, the SR value should be adjusted by strength ratio of taper...
Essential oils from fresh Piperaceae leaves were obtained by hydrodistillation and analyzed by gas chromatography mass spectrometry (GC-MS), and a total of 68 components were identified. Principal components analysis results showed a chemical variability between species, with sesquiterpene compounds predominating in the majority of species analyzed. The composition of the essential oil of Piper...
To provide baseline data for physiological studies of extreme low-temperature (LT) tolerance in boreal conifers, we profiled LT stress responses, liquid nitrogen (LN(2))-quench tolerance, and sugar concentrations in foliage of boreal-temperate species pairs in the genera Abies, Picea and Pinus, growing in an arboretum in a temperate oceanic climate from August 2006 through April 2007. The borea...
