Factors affecting storage of Yellow Globe Danvers onion : abscisic acid during maturation and storage and phenolic substances inhibitory to Botrytis allii and Botrytis cinerea

Creator:: Boonyakiat, Danai
Abstract:: Free abscisic acid (ABA) in Yellow Globe Danvers onion tissues was determined during maturation and storage. The amount of ABA in leaf tissue reached a maximum (1.81 ng/gm dry weight) at 40% top fall. Neck tissue ABA reached a maximum (0.33 ng/gm dry weight) at 60-70% top fall. ABA of...

The chemical curing of Oregon Danvers onions

Creator:: Bubl, Charles Edward
Abstract:: Pre-harvest foliar desiccation of Yellow Globe Danvers onions was investigated as a means to improve harvest procedure and to reduce storage losses. Foliar desiccation tended to increase storage disease and sprouting incidence versus the untreated controls. Paraquat approximately doubled storage disease in both years. Stoddard solvent and ethephon increased disease...

Biological assessment of soils for potential development of take-all root rot

Creator:: McGeehan, Steven L.
Abstract:: Take-all root rot (Gaeumannomvces araminis var.tritici) is a major disease of wheat (Triticum aestivum) in western Oregon. Control of take-all is dependent on management practices such as crop rotation and soil fertility-plant nutrition relationships. The objective of this study was to develop a bioassay that could measure the influences of...

Environmental Factors Affecting Phytophthora Root Rot of Rhododendron

Creator:: Mestas, Angie
Abstract:: Phytophthora root rot decreases availability and quality of rhododendrons produced in the USA. Symptoms of Phytophthora root rot include root necrosis, leaf chlorosis, stunting, and permanent wilt. The purpose of this thesis was to better understand the impact of root damage, soil moisture, nitrogen fertilizer application, and pathogen species on...

Factors affecting inter-tree root contact and the transmission of Phellinus weirii in young-growth Douglas-fir

Creator:: Reynolds, Keith M.
Abstract:: Groups of second-growth Douglas-fir (Mirb.) Franco were excavated in plots of two to six trees on two sites in the vicinity of Cowichan Lake, Vancouver Is., British Columbia. Eleven excavation plots provided 36 trees which could be studied in pairs (a total of 50 pairs) in order to ascertain the...

Effect of resident epiphytic fungi development of brown rot blossom blight of stone fruits

Creator:: Wittig, Hans P. P.
Abstract:: Antagonistic effects of Epicoccum purpurascens, Aureobasidium pullulans, Trichoderma spp., and Botrytis cinerea on establishment of Monilinia fructicola infections in cherry and peach blossoms were assessed in field and mist chamber studies. Conidia of each fungus were applied to blossoms that were subsequently inoculated with conidia of M fructicola. Mist chamber...
