Creator:: Schisler, David Albert
Abstract:: Fusarium spp. frequent conifer nursery soils yet are rarely recovered from coniferous forest soils. Experiments were performed to determine what influence humic-rich organic amendments and volatiles from soil, ectomycorrhizal fungi and ectomycorrhizae have on the populations of several physiologic and taxonomic microbial groups potentially related to this phenomenon. A comparative...

Creator:: Woods, Wendy W.
Abstract:: The abundance of algal species and their parasites was monitored weekly for two years in a sewage lagoon at the Corvallis Airport, Oregon. During the cooler months, Euglena species were dominant followed by a Chlamydomonas assemblage in the spring and a predominantly Scenedesmus assemblage in the summer and fall. Parasites...

Creator:: Hural, Kirsten
Abstract:: The influence of atmospheric humidity on three aspects of sporulation of Sphaerotheca pannosa (Wallr.) Lev. var. rosae Wor., which causes rose powdery mildew, was studied on leaf disks of susceptible Rosa cultivar Samantha. To study conidiophore production, leaf disks were inoculated on the adaxial (upper) surface with conidia of S....

Creator:: Valverde, Bernal E.
Abstract:: Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from North Carolina, South Carolina, and Mississippi was analyzed in greenhouse experiments. Leaf area and biomass measurements, including root, shoot, above-ground, and total dry weights were similar among the biotypes studied....

Creator:: Lopez-Jurado, Gerardo
Abstract:: Field experiments were established in 1982 and 1983 on a Woodburn silt loam soil (Aquultic Argixeroll) to examine the effect of S fertilizer on dinitrogen fixation and dry matter yield of 10 week-old seedling alfalfa (Medicago sativa L. cv. 'Apollo'). Six levels of S fertilizer (0 to 67.2 kg S/ha)...

Creator:: McCoy, Edward L.
Abstract:: The principles of continuum mechanics provide a consistent framework for the derivation of mathematical statements describing transport of water and solute, and growth in plant tissue. These derivations are based upon the explicit consideration of the tissue as a mathematical continuum composed of a cell wall matrix, water, and solute...
