Sampling studies were conducted to compare the efficiency of the four officially recommended methods of sampling small seeds: automatic sampling--at two sampling speeds, hand sampling, Nobbe tier sampling, and stick trier sampling. Synthetic lots of orchard-grass, ryegrass, Kentucky bluegrass, and alfalfa seed were prepared containing known numbers of the common...
A comparison of the agglutinating and precipatiating
antigens of Enteric Redmouth Bacterium (ERMB) was made.
There are two major and one minor agglutinating antigens
which describe two serotypes (I and II). Only serotype I
metabolizes sorbitol. A bacterin from serotype I cross
protected against a challenge of bacteria of serotype...
Populations of coastal cutthroat trout, Oncorhynchus clarki clarki, were sampled in 16 headwater streams from logged (20-30 and 40-60 years ago) and unlogged (stand age 125-150 years) basins. Basins logged 20-30 years ago supported the widest range of mean biomass of age 1+ or older cutthroat trout (g/m2) and the...
Extensive information on rootstock resistance to lime is available since it has been one of the major selection criteria in Europe an rootstock breeding programs. Information regarding the performance of rootstocks in acidic soils however, is not so prevalent. Differences in genotype tolerance to high acidity maybe related to different...
