Hard Fescue (Festuca longifolia Thuill.) has potential for in
creased turf use but does not respond well to normal seed production
management practices in Oregon. Field burning (the normal residue
management practice) results in reduced seed yields in commercial hard
fescue seed production fields but stimulates seed production in Chewings...
Dihydroquercetin [(2,3-trans)-3,3',4',5,7-pentahydroxyflavanonol]
was shown to be the precursor to the phenolic
stains that often develop in Douglas-fir [Pseudotsuga
menziesii (Mirb.) Franco] sapwood. Douglas-fir sapwood was
extracted with methanol and the methanol solubles were
fractionated by solvent partition, thin-layer chromatography,
silica-gel column chromatography, and Sephadex gelpermeation
chromatography. Tyrosinase, a commercially
available...
Nursery plants are often harvested, stored, and shipped bare-root for easier
and more economical handling. Some species of woody and herbaceous
perennials are less tolerant of postharvest handling than others. Desiccation
stress during the handling of bare-root plants has been identified as a major
problem contributing to poor survival and...
