Recovery of Penncap-M from Foraging Honey Bees and Pollen Storage Cells

Creator:: Burgett, D. Michael and Fisher, Glenn C.
Abstract:: Foraging honey bees (Apis mellifera L.), exposed to birdsfoot trefoil (Lotus corniculatus L.) bloom treated with microencapsulated methyl parathion, continued to display pollen and midgut microcapsule contamination up to 9 days postspray. Nearly 10% of all pollen storage cells examined in combs taken from honey bee colonies exposed to the...

Development of an in vitro and modification of an in vivo bioassay to screen cherry genotypes for response to inoculation with Pseudomonas syringae pv. syringae

Creator:: Roche, M. Margaret
Abstract:: The bacterium Pseudomonas syringae affects different crops worldwide. In the Willamette Valley of Oregon, P. syringae causes bacterial canker in sweet cherry, severely limiting its production. High grafting of susceptible sweet cherry cultivars to resistant rootstocks is practiced in the Willamette Valley to reduce incidence of this disease. The research...

Micropropagation and regeneration of hazelnut (Corylus species)

Creator:: Yu, Xiaoling
Abstract:: A micropropagation system was developed for hazelnut cultivars and rootstocks. Culture establishment was affected by explant source, explant collecting season, and type of explant. The highest frequency of culture initiation and lowest tissue oxidation and contamination were obtained from internodes with single axillary buds from grafted greenhouse-grown plants early in...

Improving nitrogen management with cover crops in organic broccoli production

Creator:: Garrett, Amy
Abstract:: Legume cover crops can serve as important sources of nitrogen (N) in sustainable agriculture and can be economically beneficial when fertilizer inputs are reduced without a yield reduction. Synchronizing N mineralization from organic materials with the needs of the subsequent crop is a challenge for organic growers. Predicting plant available...

Nondestructive evaluation of in vitro-stored plants : a comparison of visual and image analysis systems

Creator:: Aynalem, Hailu M.
Abstract:: In-vitro plants in slow-growth storage must be routinely evaluated for repropagation and assessment of viability. It is often difficult to determine plant health by visual assessment due to variation in growth patterns and plant structure among genera. In order to evaluate cold-stored germplasm, laboratories need more effective approaches for viability...

Pressure trunk injections of potassium as a possible short term corrective measure for potassium deficiency in sweet cherry (Prunus avium L.) and prune (Prunus domestica L.)

Creator:: Robbins, Scott Hill
Abstract:: The effect of pressure trunk injections of K₂HPO₄, and K₂SO₄. solutions on the mineral content, growth, yield and fruit quality of sweet cherry and mineral content of prune were investigated. A complimentary study presented in Appendix 1, was conducted to evaluate the short term effectiveness of K soil amendments, mulching...

Suitability of diverse composts as soil amendments for highbush blueberry (Vaccinium corymbosum L.)

Creator:: Costello, Ryan C.
Abstract:: Highbush blueberry (Vaccinium corymbosum L.) is adapted to soils with high organic matter and acidic pH. Composts provide organic matter and nutrients for growing blueberry in mineral soils, but many composts are high in pH and soluble salts. Acidification with elemental sulfur (S°) can remedy high pH, but the process...
