The experiments in this thesis are reported as two journal
articles. The first article. The effect of rootstock and scion on
above- and below-graft leaf mineral nutrient content of sweet cherry,
is a field sampling experiment dealing with the effect of Stockton-
Morello and F 12-1 mazzard rootstocks on 'Royal...
Thiamin and ascorbic acid content and retention were determined
in raw, blanched, pouched and canned green beans immediately
after processing and after storage for four months at room temperature
or at 37.5°C. Ascorbic acid was also determined in raw, pouched
and canned Royal Ann cherries immediately after processing and after...
Research was initiated to find a secondary bleach to remove brown discoloration on sulfur dioxide brined sweet cherries. In addition, studies were carried out to determine the effects on texture of not only the secondary bleaches, but also the primary bleach (sulfur dioxide). Three bleaches were found to remove the...
Oregon's Willamette Valley sweet cherry growers have
developed a market for large, high quality, stem-on brining cherries.
The maturity indices pull force (PF), percent soluble solids (SS),
and weight (Wt) were chosen as being the most probable indicators of
maturity.
The rate of change of PF during the harvest period...
Air temperatures and soil temperatures at the surface, two inches,
and four inches under a grass cover were recorded over a 93 day period.
These data were used along with other temperature data from bare soil
in the construction of three sets of models for the prediction of
maximum and...
The structure of the Royal Anne cherry cuticle (Prunus avium
L.) and its penetration by a SO₂-calcium bisulfite brine was determined. The structural features of the cuticle are interpreted in the
light of its possible significant to cuticular penetration.
The morphology of the cuticle was determined by standard
histological and...
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...
Ten, twenty, and thirty percent of dextrose were used
in place of sucrose to preserve the Maraschino-type cherries
because of the expectation that the smaller sized molecules
would enter the cherry tissue more readily and thus increase
the weight and volume of the fruit. Other samples, sucrose
and percent dextrose...
