Osmotic stress vigor test for wheat seed

Creator:: Currans, Sean
Abstract:: Seed vigor tests have been developed to evaluate the relative ability of seed lots to produce stands of seedlings in the field. Some workers have suggested the possibility of differentiating vigor levels by germinating seeds under osmotic stress, but have not conducted field trials to evaluate the usefulness of the...

Nucleotide sequence of two chloroplast genes from a Chlorella-like green alga : the large subunit of Ribulose-1,5-bisphosphate carboxylase/oxygenase and ribosomal protein S14

Creator:: Amberg, Sean M.
Abstract:: Chlorella is a genus of unicellular, enkaryotic green algae. Chlorella-like algae are found as endocellular symbionts within a number of animal species. Two chloroplast genes were sequenced from the exsymbiotic strain Chlorella N la, originally isolated from Paramecium bursaria. The genes for the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcL) and...

The effect of forest stand thinning on selected strength and pulp-ing characteristics of Douglas-fir

Creator:: Johnson, Donna A.
Abstract:: The purpose of this study was to determine if amount and kind of thinning had an effect on wood specific gravity, modulus of rupture, modulus of elasticity, growth rate, or pulp yield and kappa number. The study involved 24 1/5-acre plots, three plots in each of eight thinning treatments. The...

Design, construction and application of an instrument for simultaneous measurement of molecular fluorescence, absorbance and chemiluminescence

Creator:: Yappert, Marta Cecilia
Abstract:: An instrument was constructed to measure molecular fluorescence (FL) or chemiluminescence (CL) and absorbance (ABS) simultaneously. The lower, middle, and upper portions of the test solution are probed to obtain ABS, FL, and CL data. Optical fibers are used extensively. The ABS and FL or CL spectra are acquired in...

Factors in the Selection of Home Birth : A Comparative Study of Birthing Alternatives in Western Oregon

Creator:: Fuhr-Dunn, Susan D.
Abstract:: Increasing demand for home birth has created an upheaval in the American medical profession and, is a controversial political and legal issue as well. This research, utilizing ethnographic, historical, and survey data analyzes contemporary home birth. A review of the so called "medicalization" of childbirth is presented noting that the...

Factors affecting stand establishment and yield of meadowfoam (Limnanthes alba Benth.)

Creator:: Nyunt, San
Abstract:: Germination of meadowfoam (Limnanthes alba Benth.) seed is inhibited by warm soil temperatures. This has led to recommendations for planting from early to mid-October when soil temperatures are below about 15°C. Objective data on the effects of planting date on stand establishment and yield are not available. These studies were...

Effect of seed deterioration on germination of wheat under environmental stresses

Creator:: Than, Mya
Abstract:: Germinating seeds often encounter stress conditions of temperature, moisture and oxygen in the field. Germination tests conducted under these stress conditions in the laboratory might be methods of differentiating high and low vigor seeds. The objectives of this study were to (1) determine if these stress conditions reduce germination performance...

Horticultural weed control report : 1980-81

Creator:: Oregon State University. Department of Horticulture
Abstract:: Crops were grown using accepted cultural practices within the limits of experimentation or trials were conducted on growers' fields, Most experiments were designed as randomized complete blocks with two to five replications. Herbicide treatments were applied uniformly with equipment ranging from precision plot sprayers to quart jars (granular applications). Unless...

Characterization of antibiotic resistant enteric bacteria that contaminate vegetables

Creator:: Salama, Maysoon
Abstract:: Previous studies revealed the high incidence of drug resistant bacteria from foods. In this study, market vegetables were tested for their contamination with antibiotic resistant (ABR) enteric bacteria. A total of 402 bacterial strains from surface vegetables (e.g., lettuce) and 321 from root vegetables (e.g., carrots) were examined for their...
