Effects of stand density on site index in thinned stands of Douglas-fir in the Pacific Northwest

Creator:: Zumrawi, Abdel Azim M. A.
Abstract:: In site index studies, the hypothesis that height growth of most conifers is independent of stand density is commonly accepted. However, some studies have shown height growth to be influenced by density particularly on medium to poor sites. In this study two locations representing a high quality site (Hoskins area,...

Fish oral antigen delivery system development and optimization

Creator:: Zhang, Jia Ai (Allen)
Abstract:: Oral administration is the most practical way of vaccination of fish. It has advantages over intraperitoneal injection and immersion methods that include no stressful handling, no interference with routine fish husbandry and antigens can be delivered to the fish in their feed. An oral antigen delivery system was developed for...

Acute and chronic toxicity studies with monochlorobenzene in rainbow trout

Creator:: Dalich, George M.
Abstract:: The toxicity of chlorobenzene (CB) was investigated in rainbow trout following acute ip administration (1. 0 ml/kg, 1:1 in corn oil) and chronic exposure (2. 1 ppm and 2. 9 ppm) via the water in a continuously flowing system for 15 and 30 days. In the acute study, overt toxicity...

Responses of males to a pheromone blend of female Oriental fruit moth with and without E8, E10-dodecadien-1-ol, a pheromone component of codling moth (Lepidoptera: Tortricidae)

Creator:: Allred, Darin B.
Abstract:: E8,E10-dodecadien-1-ol, the primary component of the female sex pheromone of codling moth, Cydia pomonella L., has no attraction to male Oriental fruit moth (OFM), C. molesta (Busck). However, this compound when added to the OFM pheromone blend of Z8-dodecenyl acetate (85.5%), E8-dodecenyl acetate (5.5%), and Z8- dodecen -1 -ol (9.0%),...

Production of haploid plants in selected winter wheat genotypes through anther culture and intergeneric crosses with maize

Creator:: Mendoza, Maria Graciela
Abstract:: A higher level of efficiency in the production of doubled-haploids must be achieved if this procedure is to be beneficial in plant improvement. Of equal importance is the development of protocols, which are not genotypic specific and result in progeny that represent a random sample of gametes from the parental...

Food preferences of Thai adolescents and their mothers' attitudes and knowledge about foods and nutrition

Creator:: Sananmuang, Ratana
Abstract:: The purpose of this study was to investigate the relationships between adolescents' food preferences and their mothers' attitudes and knowledge about foods and nutrition in Phitsanulok Province, Thailand. Subjects included 30 boys and 35 girls randomly selected from 11th grade classrooms at two high schools in Phitsanulok, and their mothers....

Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

Phylogeny and zoogeography of glyptocephalines (Pisces: Pleuronectidae)

Creator:: Chiu, Tai-sheng
Abstract:: Hypotheses of phylogenetic and historical zoogeographic relationships of glyptocephalines (Glyptocephalus cynoglossus, G. zachirus, G. stelleri, Microstomus kitt, H. pacificus, H. achne, Embassichthys bathybius, and Tanakius kitaharae) were constructed based on comparative anatomy and external morphology. The phylogenetic approach was cladistic and character polarity was determined by using out-group comparison. One...

Forest ant composition, relative abundances, and foraging following aerial spraying of carbaryl to suppress Western Spruce budworm

Creator:: Murphy, Christopher F.
Abstract:: An outbreak of western spruce budworm Choristoneura occidentalis in the Blue Mountains of eastern Oregon in 1983 was treated with helicopter applied carbaryl. Effects of the spraying on forest ants were determined from pre- and postspray samples taken from two carbaryl sprayed and two unsprayed plots. In each 0.75-ha plot,...

Interactions between the immune system, stress and thymulin

Creator:: Christian, Richard L., (Richard Leroy), 1971-
Abstract:: This study was conducted to determine the effects of shipping stress on the immune system in domestic lambs (Ovis aries) and to determine the potential of the thymic peptide, thymulin, to reduce those effects of stress on the immune system. Treatments consisted of no shipping (as unstressed controls), shipping (as...
