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...

Onion (Allium cepa L.) cultivar tolerance to bromoxynil

Creator:: Madrid, Modesto T.
Abstract:: In onions, sensitive cultivars diminish the usefulness of the selective herbicide bromoxynil. Tolerant cultivars can overcome this limitation. A better understanding of the biochemistry, physiology and genetics of bromoxynil tolerance could lead to improved weed control programs in onions. Onion cultivar response to bromoxynil was studied under greenhouse conditions. Tolerant...

Inheritance of resistance to Fusarium root rot in Phaseolus vulgaris L., and Phaseolus coccineus L.

Creator:: Azzam, Hassan Ahmed
Abstract:: Progenies of two bean crosses were studied for inheritance of resistance to dry root rot caused by Fusarium solani f. phaseoli. O.S.C. 22 (P. vulgaris) was used in both crosses as the susceptible parent. A Mexican line (P. vulgaris) and a line 2014 of the runner bean (P. coccineus) were...

Mapping QTL for root rot resistance, root traits, and morphological trait in a common bean recombinant inbred population

Creator:: Hagerty, Christina H.
Abstract:: Root rot diseases of bean (Phaseolus vulgaris L.) are a problem wherever they are grown, and are a major constraint to dry edible and snap bean production. Root rot is a primary yield limitation of snap bean production in the US, especially within the top three snap bean producing states...

Determining novel control methods for cabbage maggot (Delia radicum) in the Pacific Northwest

Creator:: Dugger, Chloe D.
Abstract:: Cabbage maggot, Delia radicum (Diptera: Anthomyiidae) impacts the production of Brassicaceae crops worldwide. The larva feed on the roots of crops causing reductions in yields due to impaired root function and unmarketability of crops. Chemical and cultural management programs are commonly used to control cabbage maggot with varying rates of...

Winter Squash: Production and Storage of a Late Winter Local Food

Creator:: Wetzel, Jennifer D.
Abstract:: Winter squash is an important late winter vegetable crop for local and regional markets; however, farmers in western Oregon report that this crop is marginally profitable due to losses in storage and relatively low yields for the high culinary value kabocha and buttercup types. In order to increase the sales...

Population dynamics, distribution, and control of nematodes in highbush blueberries

Creator:: Schroeder, Jan-Marie
Abstract:: Fluctuations in population density of Pratylenchus sp., Trichodorus sp., and Xiphinema americanum s. 1. in three blueberry fields were determined monthly for one year. Pratylenchus densities were greatest in August and least in October. Three distinct periods of population growth occurred; during January, April, and between June and August. Trichodorus...

On-farm inquiry and assessment of tillage and cover cropping for white mold control in snap bean production

Creator:: Harrison, Elizabeth Langham.
Abstract:: Cultural practices in snap bean production were evaluated at the Oregon State University Vegetable Research Farm Corvallis, Oregon. In addition, decision-making in snap bean production was assessed on five farms in the Coburg-Junction City-Harrisburg regions of the Willamette Valley, Oregon. A field experiment with cover crop and tillage techniques was...
