Abstract:: There are over 35 known virus and virus-like diseases of sweet cherry (Prunus avium), some with potential to cause severe economic impact by reducing vegetative growth, vigor, and/or quality of fruit. Oregon is the second-ranked state for sweet cherry production in the United States with 13,000 acres and $70.8 million...

Creator:: Lawson, Roger Harold
Abstract:: Three viruses were isolated from dahlias using a modification of Yarwood's leaf-disc method of inoculation. Two of these isolates have been reported previously in dahlias. In addition, a fourth virus was isolated using a liquid-nitrogen transmission technique. Dahlia virus isolate 1 possessed host range and thermal inactivation properties similar to...

Abstract:: Recent investigations indicate that several latent viruses of apples exist in common commercial apple stocks, but these viruses and their relationships are incompletely understood. This thesis describes investigations of crab apples as indicators of latent viruses of apples. Eighty-eight varieties and species of crab apples were tested as indicators of...

Creator:: Xu, Ling, 1963-
Abstract:: Polyclonal antisera were raised against isolates of bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV) using conventional serological methods. Infected tissues containing, respectively, 22 recognized BCMV and BCMNV isolates were tested against the two antisera by antigen-coated plate (ACP) ELISA and double antibody sandwich (DAS) ELISA....

Creator:: Ruttum, Joanne C.
Abstract:: Lily hybrids vary in their ability to produce virus-free (VF) bulblets when grown from virus-infected scales in tissue culture. Asiatic hybrids typically produce a higher percentage of in vitro VF scale bulblets than do Lilium longiflorum cultivars. Three hypotheses concerning the cause of this variation are tested on five lily...

Creator:: Halgren, Anne B.
Abstract:: The objective of this study was to characterize an unknown agent associated with decline in black raspberry (Rubus occidentalis) in Oregon. A virus was found consistently associated with decline symptoms of black raspberries and was named Black raspberry decline associated virus (BRDaV). Double stranded RNA extraction from BRDaV-infected black raspberry...

Creator:: Quito-Avila, Diego F.
Abstract:: The United States is the third-largest producer of raspberries in the world. Washington State leads the nation in red raspberry (Rubus idaeus L.) production. 'Meeker', the most grown red raspberry cultivar in the Pacific Northwest (Washington, Oregon and British Columbia, Canada) is highly susceptible to Raspberry crumbly fruit, a virusinduced...
