Serological and molecular approaches for distinguishing bean common mosaic and bean common mosaic necrosis potyviruses and their respective pathogroups

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....

The use of flowering crab apples for the detection of latent viruses in apples

Creator:: Reynolds, James Edward
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...

Succession and certain adaptive features of plants native to the sand dunes of the Oregon coast

Creator:: Kumler, Marion Lawrence, 1941-
Abstract:: The vegetation of the Oregon coast is characterized by a variety of stages of plant succession which are repeated widely throughout the sand dune area. During the years from 1960 to 1963 the gradation of upland sand dune succession was studied on 48 plots within a 150 mile section of...

Relation of nitrogenous substances in rose leaves to powdery mildew resistance

Creator:: Bartlett, Allan B.
Abstract:: There is considerable variation among rose varieties in susceptibility to mildew, and as a result of maturation, leaves of most susceptible varieties become resistant to infection. The nature of resistance has been sought in various studies involving environmental, morphological, and physiological factors. An attempt was made in the present investigation...

Fungitoxicity of silver salts

Creator:: Guilford, Roger Kirby
Abstract:: The demand for new fungicides to control plant diseases has led to experimentation with both previously used and newly developed fungicides. Silver, an older but little used fungicide, was selected for evaluation because of its high toxicity to microorganisms. Silver nitrate and a silver electrolytic cell were tested as potential...

Isolation and identification of dahlia viruses

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...

Production of pectic enzymes by Verticillium albo-atrum

Creator:: McIntyre, Gary Allen
Abstract:: The main objectives of this study were to determine the effect of certain environmental conditions on the quantity of poly-galacturonase (PG) produced by V. albo-atrum, and to partially purify and characterize the PGs produced by this fungus in culture and in infected tomato plants. V. albo-atrum produced twenty times as...
