Floods and ensuing damage have always been a problem for man.
Initial reaction to the frequent destruction was to avoid siting
permanent domiciles on flood-prone lands. As a result of increasing
population and pressure for development, flood control structures
were built. Instead of reducing flood losses, however, flood control
projects...
Thirty-three genotypes of red fescue were selected on the
basis of diverse origin, anthesis date, and type of spreading from a
space-planted introduction nursery.
Open-pollinated, single-cross, and top-cross progeny
nurseries were established into a randomized block with four replications,
20, 9, 8 entries, respectively, with nine plants per entry
on...
Six parent clones and their 15 single-crosses of tall fescue (Festuca arundinaceae, Schreb) were row-planted in Corvallis, Oregon, row and sward-planted in Columbia, Missouri, and evaluated for genetic variability, genotyp-eenvironment interactions and interrelationships in acid detergent fiber (ADF), neutral detergent fiber (NDF), hemicellulose (HCL), crude protein (CP) and in vitro...
In the last 30 years, birdsfoot trefoil (Lotus corniculatus L. )
has been recognized as a great potential source of forage. Since the
1930's, many studies have been reported in relation to birdsfoot
trefoil characteristics, including some directly related with the
association between seed yield and its components.
The purpose...
Two diverse genotypes of tall fescue, Festuca arundinacea Schreb (6X=42), with normal fertility, produced upon intercrossing, vigorous F

hybrid plants that were sterile. One parent genotype (P₁)
was from P. I. 234-906, introduced from Switzerland and the other
(P₉) was an introduction from Turkey, P. I. 174-209. P₁

The turbulent interchange of matter between parallel adjacent
subchannels in a simulated rod bundle for single phase flow was investigated
to determine the effects of mass flow rate and rod spacing.
The simulated rod bundle was made by placing six 1-inch diameter
rods in a square-square array. The overall test...
