Spring grazing of annual ryegrass (Lolium multiflorum L.) seed
fields with sheep is a common practice in the Willamette Valley of
Oregon. However, the effect of grazing on seed yield in Oregon has
not previously been investigated. This experiment was designed to
determine the effects of duration of spring grazing...
The relationship between Leaf Area Index (LAI) and current stem-wood
production was examined in selected stands in eastern
Washington. Stands were sampled with an angle gauge (prism). LAI
was estimated from sapwood area; current stem-wood production from
DBH, height, and radial increment.
Maximum LAI attainable on a given site has...
Lodgepole pine seedlings were used to test a general hypothesis of how water and nitrogen stress affect a plants' monoterpene composition. Four treatments, consisting of high and low levels of both water and
nitrogen, were applied to the trees. Growth measurements, consisting of shoot and needle lengths, needle fresh weights...
