In vitro culture and growth modeling of Tuber spp. and inoculation of hardwoods with T. melanosporum ascospores

Creator:: Michaels, Thomas Joseph
Abstract:: In vitro growth of twelve isolates of Tither spp., the true truffles, was quantified by an agar-melt procedure. All isolates grew poorly on media commonly used for the culture of mycorrhizal fungi, but responded markedly to the addition of nitrate, as well as other inorganic ions, to malt and potato-dextrose...

The growth of wild-type and genetically-marked strains of Tilletia caries and T. controversa in susceptible and resistant wheat cultivars

Creator:: Trail, Frances
Abstract:: The objective of this study was to provide basic information on the interaction of the bunt fungi Tilletia caries and T. controversa with their host, Triticum aestivum. Studies on the ability of haploid strains to colonize wheat heads provided the basis for experiments in which haploid strains were crossed in...

A systematic and ecological study of Astragalus diaphanus (Fabaceae)

Creator:: Wright, Carolyn E.
Abstract:: Astragalus diaphanus is a rare plant endemic to the John Day River drainage of north-central Oregon. This species has several interesting features, including the dimorphism of its fruit and its geographical isolation from the two nearest taxonomically related species, which occur in Colorado. This study addressed the species' distribution and...
