Growth of individual goosegrass (Eleusine indica (L) Gaertn.) plants of
three dinitroaniline-herbicide resistant (R) and three susceptible (S) biotypes from
North Carolina, South Carolina, and Mississippi was analyzed in greenhouse
experiments. Leaf area and biomass measurements, including root, shoot,
above-ground, and total dry weights were similar among the biotypes studied....
The leaching of water soluble phenolic compounds from
cold stressed Rhododendron leaves was found to be a reliable
indicator of tissue damage. In sublethally stressed leaf
tissues, more and novel phenolic compounds appeared and were
hypothesized to be precursors of cell wall components such
as lignin and suberin. Subsequent radiolabeling...
The lag phase, the specific growth rate, the minimum a [subscript w]
required for growth and the temperature characteristic of
Fsendomonas fluorescens, Brochothrix thermosphacta, Salmonella
typhlmurium, Streptococcus faecalis and, Staphylococcus aureus
have been studied in liquid model media under controlled temperature
and a [subscript w] conditions. The results show that...
The purposes of the research presented in this thesis were
to: (l) assess the nutritional status of vegetarian and nonvegetarian
Seventh-day Adventists (SDA), non-SDA non-vegetarians,
and non-vegetarian hormone dependent cancer subjects; (2) determine
the relationship of various blood and urinary biochemical
parameters to dietary intake; (3) determine hormonal status in...
The biology of the two external Acarapis mites of honey bees,
Acarapis dorsalis Morgenthaler and Acarapis externus Morgenthaler
was studied. It was observed that both Acarapis species have similar
developmental period (8-9 days) with males emerging earlier than
females.
Mite load and infestation rate of A. dorsalis decreased as bees...
Microgard, a commercially-available pasteurized
fermented milk, was found inhibitory to gram negative
bacteria such as Pseudomonas putida, some well-known foodborne
pathogens (e.g. Salmonella, Yersinia and Aeromonas)
and some fungi as revealed by an agar incorporation assay
method. Gram positive bacteria, however, were not
inhibited. Rather, some bacteria in this group...
The project presented here emphasizes a specific biological problem affecting the salmon cage culture with the final goal being to propose a realistic management strategy for fjordic estuaries worldwide.
