Methylisothiocyanate as a wood fumigant : fungitoxicity to Poria carbonica in wood and gelatin encapsulation for use in wood products

Creator:: Zahora, Andrew Roy
Abstract:: Experiments were conducted to determine both the influence of wood moisture content on the fungitoxicity of methylisothiocyanate (MIT) to the wood-decay fungus Poria carbonica, and the ability of gelatin to safely en-capsulate MIT for efficient treatment of wood products. The fungitoxicity of MIT was studied by determining the product of...

Anatomical changes in the secondary phloem of grand fir (Abies grandis (Dougl.) Lindl.), induced by the balsam woolly aphid (Adelges piceae Ratz.)

Creator:: Saigo, Roy Hirofumi
Abstract:: The balsam woolly aphid (Adelges piceae Ratz.) feeds by inserting its stylets intra- and intercellularly into the cortex or outer phloem of the true firs. While feeding, the aphid injects into the bark an unknown stimulatory substance which affects the adjacent cortical parenchyma cells, the activity of the vascular cambium...

The effects of DMSO on wound periderm formation in potato tuber tissue

Creator:: Davidson, Roy M., 1939-
Abstract:: A study was conducted to determine the influence of DMSO (dimethyl sulfoxide) on suberization and wound periderm formation in cut potato tuber tissue, and to determine the effectiveness of DMSO as a potato seedpiece treatment for prevention of seedpiece decay in the field. The influences of tuber storage conditions, varieties,...

Contracting nucleolar vacuoles in somatic tobacco cells growing in microcultures

Creator:: Johnson, John Morris
Abstract:: Contracting nucleolar vacuoles are a general and consistent feature of somatic tobacco cells growing in microcultures. Nucleolar vacuoles were studied in cells from callus tissues of two single-cell clones, H-196 and H-239, of hybrid tobacco (Nicotiana tabacum X N. glutinosa). Vacuoles periodically contracted either completely or incompletely, apparently releasing a...

Ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae)

Creator:: Campanella, Donald M.
Abstract:: A study consisting of three parts was undertaken to investigate how variation in species interactions, population genetic structure, epidemiological parameters, and plant breeding system may influence the ecology and biological control of an apomictic invasive plant, Chondrilla juncea (Asteraceae). Interactions between natural enemy species may modify their net effect on...

Cytokinin oxidase activity from Phaseolus vulgaris L. cv. Great Northern callus tissues

Creator:: Chatfield, J. Mark
Abstract:: Cytokinin oxidase activity in callus tissues of Phaseolus vulgaris L. cv. Great Northern has been examined using an assay based on the oxidation of radioactively labeled N⁶ -(Δ² -isopentenyl) adenine (i⁶Ade) to adenine (Ade). Conditions for the quantitative extraction and assay of the enzyme have been established. The substrate specificity...

The Influence of Nitrogen Fertility on Hop Quality, Pest Management, and the Stability of Biological Control

Creator:: Iskra, Anne E.
Abstract:: A multi-year field study was conducted in Oregon and Washington to evaluate the influence of nitrogen fertilization rate and timing on cone quality, nitrate accumulation in cones, severity of powdery mildew (caused by Podosphaera macularis), arthropod pests, and the stability of conservation biological control of the twospotted spider mite (Tetranychus...

Incompatibility reactions and nuclear condition of three Phellinus species

Creator:: Hennon, Paul E.
Abstract:: Phellinus arctostaphyli (Long) Niemela, P. igniarius (L. ex Fr.) Quel., and P. tremulae (Bond.) Bond. et Boriss., heartrotting hymenomycetes in the family Hymenochaetaceae (Aphyllophorales), all conform to a multi-allelic heterothallic mating system. Both compatible and incompatible reactions result from pairings of homokaryons from the same basidiocarp. Homokaryons isolated from different...
