Alfalfa sprouts have been implicated in several salmonellosis outbreaks in recent years. Electrolysis of a NaCl solution generates, in the anode side of a two-chamber electrolyzer, acidic electrolyzed oxidizing (EO) water which contains Cl₂, HOC1, dissolved oxygen, and it is characterized by a low pH and a high oxidation reduction...

This paper presents a review of existing literature concerning sprout suppression in stored potato. Currently available synthetic chemical suppressants are discussed and compared to alternative suppressants such as essential oils. Literature examining the efficacy of various commercially available essential oil products on potato sprout suppression are reviewed, and other essential...
Residual roots from previous stand components are often cited as a major benefit to stump-sprouts of tanoak in southwest Oregon and northern California. Established patterns of belowground carbon allocation and root/shoot maintenance suggest that residual root systems of stumps
will be reduced by carbohydrate depletion and root mortality and by...
Estrogen is a sex hormone responsible for the development and regulation of the reproductive system and secondary sex characteristics. They also play a critical role in the development of breast and uterine cancer. The formation of agonistic metabolites of estrogen, especially 16α-hydroxyestrone, have been found to have cancer-inducing effects meanwhile...
Tanoak (Lithocarpus densflorus (Hook and Am.) Rehd.), an evergreen hardwood tree that grows abundantly in southwest Oregon and
north California, sprouts vigorously after a disturbance, such as logging or fire These sprouts form clumps that can hamper conifer
regeneration on clearcuts and in shelterwoods. In order to obtain a quantitative...
Consuming cruciferous vegetables such as broccoli sprouts, kale, Brussels sprouts, and bok choy is associated with several health benefits, such as a decreased risk of certain cancers. Cruciferous vegetables contain the glucosinolate, glucoraphanin (GFN). Cutting, chopping or chewing these vegetables releases the enzyme myrosinase, which transforms GFN into sulforaphane (SFN)....
The consumption of cruciferous vegetables is associated with several health benefits, including cancer prevention. Many of these benefits are attributed to the phytochemical, sulforaphane (SFN), which is derived from cruciferous vegetables such as broccoli and broccoli sprouts. These vegetables contain glucoraphanin (GFN), SFN’s precursor, which is converted to SFN by...
Prostate cancer is the second leading cause of cancer related death in American men. Epidemiologic studies suggest that cruciferous vegetable intake may lower the risk for many cancers, including prostate and colon. Isothiocyanates (ITC) are phytochemicals derived from cruciferous vegetables such as broccoli, Brussels sprouts, cauliflower, and cabbage that may...
During the springs of 1988 1989, experiments were
conducted to determine effective methods of controlling damage
by ring-necked pheasants (Phasianus coichicus) to sprouting
corn in southwestern Idaho. Plot evaluations (1988) failed

food, and...
Salmonberry (Rubus spectabilis) and thimbleberry
(Rubus parviflorus) are clonal shrub species common to
reforestation sites in the Oregon Coast Range. These
species have economic importance, because they reduce
conifer seedling growth and survival. A population modeling
approach was used to facilitate study of the biology of
these species and to...
Pacific madrone, tanoak, and California black oak are the most economically promising native California hardwoods. Volume and value data indicate upward trends in growing stock levels and prices received for their products. These trends are likely to continue. They suggest research is particularly needed for: (1) seed fall and
regeneration,...
Quaking aspen (Populus tremuloides) is an important tree species in the western United States and there has been much concern about its persistence. In this thesis, I report on aspen in a portion of its range that has not been previously evaluated: the eastern and western slopes of the Central...
Four experiments were conducted to evaluate the effects of
growth-promoting treatments on potato sprouts and plantlets grown in
vitro, and to determine the relationships between growth rate and

The approach consisted of exposing plant material to potential
growth-regulating treatments, selecting the more...
Giant chinquapin (Chrysolepis chrysophylla) is an evergreen hardwood often found as a shrubby understory component of coniferous forests in the Pacific Northwest United States. Due to its ability to sprout quickly after disturbances such as fire and logging it is often viewed as a pest by forest managers. Like its...
More than one-fourth of the forest land in the Pacific Northwest is growing timber at reduced capacity as the result of brush encroachment. Increasing use of chemicals in brush control requires that more information be available regarding their use. Bigleaf maple, Oregon oak and vine maple are among the more...
The role of fire as a natural disturbance, its interactions with nonnative species and effects of repeated fires in the Hawaiian Islands have received little investigation.

Indole-3-carbinol (I3C), the most abundant metabolite of glucobrassicins, is
found in cruciferous vegetables such as broccoli, Brussels sprouts, cabbage and
cauliflower. I3C has been shown to have anticarcinogenic activity against many
chemical carcinogens in multiple target organs in animal models. However, the
anticarcinogenic activity of I3C is considered indirect since...
Indole-3-carbinol (I3C) is a naturally occurring plant alkaloid, found in significant concentrations in cruciferous vegetables such as broccoli and Brussels sprouts. I3C is an unstable compound that undergoes rapid oligomerization in an acidic environment to form higher order condensation products (I3C-ACPs), such as 3-3'-diindolylmethane (DIM). Both I3C and DIM are...
Targeting the epigenome, including the use of histone deacetylase (HDAC) inhibitors, is a novel strategy for cancer chemoprevention. Sulforaphane (SFN), a compound found at high levels in broccoli and broccoli sprouts, is a potent inducer of Phase 2 detoxification enzymes and inhibits tumorigenesis in animal models. SFN also has a...
While previous research has suggested that bitterness is the key determinant of vegetable disliking, it is unknown what role odor plays in vegetable hedonics. We therefore investigated the impact of odor as well as taste on liking and disliking of four vegetables (steamed asparagus and Brussels sprouts; fresh celery and...

Wheat (Triticum aestivum) is one of the world’s major staple food crops, with flour produced from starchy endosperm being used for breads, cakes, noodles and various other wheat-based foods. The unique bread making properties of wheat are primarily attributed to its gluten-forming storage proteins: gliadins and glutenins. This study investigated...

During physiological ageing of seed potatoes, the stored tuber
undergoes certain biochemical changes which cause the breaking of
dormancy and the initiation of bud growth. The ageing process can
be manipulated through storage temperature and duration. Higher
temperatures usually accelerate seed tuber ageing. In order to
define the process of...
Colonization of N. densiflorus tissues by P. ramorum is not well understood. The pathogen is able to colonize nearly all tissues of this host but it is unclear how a tree is ultimately killed. Because this is such a destructive invasive pathogen, it is important to investigate its pathogenic strategy....
