Are you longing to enjoy the fragrance and color of roses in your
yard? With thoughtful attention to planting and care, many types of
roses can be grown successfully in Central Oregon. The following tips
will help you grow this popular landscape plant.
An isolate of Coniothyrium obtained from a stem canker on
Nocturne rose from the Botany Department Farm, Corvallis, Oregon
was studied with respect to morphological and cultural characters,
pathogenicity and mineral nutrition. The hyphae of the isolate were
smooth, septate and branched. The hyphal cells averaged 16.37 X
3.52 microns....
Covers July 1, 1970 to June 30, 1971. Reports on studies of spawning and larval rearing of Manila littleneck clams, native littleneck clams, butter clams and gaper clams, including field work. "Field studies comparing growth and survival of laboratory-reared and imported Pacific and Kumamoto oysters were completed. We continued studies...
"Laboratory studies during the 1971-72 project year consisted primarily of developing mass culture and planting techniques for Manila littleneck clams (Venerupis semidecussata). Field studies continued utilizing laboratory-reared juvenile Manilas... Adult red abalone (Haliotis rufescens) were obtained from California for spawning. Experiments were initiated for culturing diatoms in the laboratory as...
"COMPLETION REPORT: July 1, 1970 to June 30, 1973" Work included laboratory and field studies of Manila littleneck clams. The work also included spawning experiments on red abalone, and monitoring of test plots of abalone.
"The Pacific Coast oyster industry is dependent upon imported oyster seed from Japan. Inconsistent quantity and quality of the imported seed is limiting growth and expansion of the oyster industry while the demand for marketable oysters is increasing. The development of oyster hatcheries on the Pacific Coast could provide the...
"The first year of the project was devoted to developing laboratory spawning and larval rearing techniques for Pacific Coast clams and oysters. The objectives of the past year were to: (1) refine these spawning and rearing techniques to achieve higher larval survival to the adult form and (2) initiate growth...
During the 1969-70 project year emphasis was placed on spawning and rearing clams which had not been previously spawned successfully. Salinity-temperature tolerances were determined for the laboratory-reared clam larvae. Field studies comparing growth of laboratory-reared and imported Pacific and Kumamoto oysters were continued. In addition, studies comparing various methods of...
This report is a brief overview of the status of Oregon’s oyster aquaculture in the mid to late 1970s, including discussions of trends in harvests and research into oyster breeding.
