This project describes a web-based information management system which has been
widely used by staff members and students at OSU. Without this system, it was very
hard for the staff members to manage a variety of fees; for example, if they want to
change a certain fee, staff members had...
This study was to determine whether postharvest hydrogen sulfide (H2S) fumigation effected surface pitting development of 'Lapins' and 'Regina' cherries after cold storage, and if so, how it minimizes surface pitting injury and its relation to cell wall metabolism. Fruit were exposed to H2S gas released from an aqueous solution...
To optimize storage quality of 'd'Anjou' pears (Pyrus communis L.) produced in the US Pacific Northwest regions, the recommended harvest maturity as indicated by flesh pressure is 67 to 58 N. Over-mature pears are more susceptible to superficial scald and inferior eating quality after storage. However, a significant portion of...
On June 20, 2017, members of the environmental engineering and science (EES) community convened at the Association of Environmental Engineering and Science Professors (AEESP) Biennial Conference for a workshop on antimicrobial resistance. With over 80 registered participants, discussion groups focused on the following topics: risk assessment, monitoring, wastewater treatment, agricultural...
Controlled atmosphere (CA) allows long-term storage of European pears (Pyrus communis L.) without chemical treatment to deliver a natural melting (buttery and juicy) texture for consumers. However, the relationship between textural properties and cell wall metabolism as influenced by O-2 regimes has not been comprehensively determined. In this study, 'Golden...
The effects of hydrogen sulfide (H2S) on storage quality, cellular water distribution, and cell wall metabolism of strawberry fruit after subjected to shelf or cold storage were investigated. Fruit were fumigated with a range of aqueous NaHS solution (0.4-3.2 mmol/L), then stored at 20 degrees C for 3 d or...
Six Ca(NO3)(2) sprays at 0.3% and 0.6% from pit hardening (PH) to 1 week before harvest (1WBH) most effectively increased Ca uptake in sweet cherry (Prunus avium). Low concentration (< 0.3%) did not affect the absorption of Ca; high concentration (> 1.6%) caused burning of leaf margins. Fruit treated with...
Recent trends towards greater fresh market use of 'Bartlett' pears has increased the need to extend its storage life to prolong the packing and marketing season in the United States Pacific Northwest region. Sixteen and 38%, respectively, of control fruit developed senescence disorders following 5 and 6 months of storage...
Liriomyza sativae and L. trifolii are highly invasive leafminer pests of vegetable crops that have invaded southern China in
recent years. Liriomyza sativae was the first of these species to invade China, but it is now being displaced by L. trifolii. The
rate and extent of this displacement vary across...
