Source identification of western Oregon Douglas-fir wood cores using mass spectrometry and random forest classification1
PREMISE OF THE STUDY We investigated whether wood metabolite profiles from direct analysis in real time (time-of-flight) mass spectrometry (DART-TOFMS) could be used to determine the geographic origin of Douglas-fir wood cores originating from two regions in western Oregon, USA. METHODS Three annual ring mass spectra were obtained from 188 adult Douglas-fir trees, and these were analyzed usin...
متن کاملAssessment of genetic diversity in Pythium aphanidermatum isolates using ISSR and rep-CR methods
Sixty isolates of Pythium aphanidermatum as the causal agent of sugar beet root rot were selected on the basis of their geographical origins, morphological and genetic diversity studies. Pathogenicity test using the Kruskal-Wallis analysis showed significant differences between the pathogenic potential of isolates. Based on the growth rate, isolates were categorized in two groups with low and h...
متن کاملEffects of Alfalfa Particle Size on Ensalivation Rate, Chewing Efficiency, and Functional Specific Gravity of Particulate Matter in Hereford Steers
Six ruminally fistulated Hereford steers (body weight=414±13 kg) were used in a switch back design to determine whether two particle sizes of alfalfa hay (18.75 and 4.65 mm theoretical cut length) influenced salivary secretion during eating. The experiment carried out in two 26-d periods, with 11-d of adaptation to ration, followed by 5 d for determining the level of voluntary feed intake, 7-d ...
متن کاملComparison of growth rate and fatty acid profile of Nereis diversicolor fed with faeces and food of rainbow trout
Rainbow trout farms released always a large amount of organic matter into the environment, resulting in environmental contamination. If these waste can be used as a food source for the production of a secondary organism such as Nereis diversicolor, in addition to increasing production, it will reduce the volume of contamination originating from fish farms. In this regard, determining the nutrit...
متن کاملGenetic diversity of Fusarium semitectum isolates from rice, using RAPD and REP-PCR markers
In order to determine genetic variability among 33 isolates of Fusarium semitectum, morpho- logical and molecular studies were carried out. Isolates from different paddy fields in the north of Iran were separated from each other in four morphotype groups. The isolates showed a high level of variation in aerial mycelium, color of colony, number of septa and growth rate on potato dextrose agar (P...
