Chloroplast DNA (cpDNA) variability and phylogeny were
studied via analysis of restriction site mutations and DNA
sequencing in a complex of three closely related species of
pines: Pinus radiata D. Don, P. attenuata Lemm., and
muricata D. Don. Genomic DNA from 384 trees representing
20 populations in the complex were...
Imaging spectra of plant tissues yield considerable potential and useful information
for basic studies and agriculture practice. We constructed an imaging spectrophotometer
with spectral range from 400 nm to 1100 nm, which was used to study various
physiological events of plant germplasm: location of bundle sheath and mesophyll cells in...
According to Engel, Blackwell, and Miniard (1993), evaluative criteria refer to
"the standards and specifications used by consumers to compare different products and
brands" (p. 51). Many studies have examined the importance of clothing evaluative
criteria used by consumers in their decision making. However, few studies have compared
the clothing...
Fresh ripe, cantaloupes were processed into juice and
juice concentrate. Processing trials were conducted on
fresh and frozen fruits with and without rind. The effects
of maceration enzymes and fining agents on yield and quality
were investigated. Compositional measurement included
°Brix, pH, titratable acidity, formol values, ascorbic acid
content, total...
It was the goal of this research to determine if sago
starch could be used to replace wheat flour as an adhesive
extender of Urea-formaldehyde plywood adhesives through
either chemical modification of the starch or modification
of the adhesive formulation strategy. Guiding principles of
the research would be that a...
Growth phenology (i.e., timing of growth initiation and cessation) is important to adaptation. This study examined the extent of genetic control of bud and cambial phenology and their relationships with stem
growth in pole-size Douglas-fir (ages 13 to 16 years) from 60 open-pollinated families. The availability of bud phenology data...
Forest soils with low bulk densities are often considered less
susceptible to compaction than soils with higher bulk densities. The
objective of this study was to determine if soil strength controlled the
compression of soils with low bulk density. Four soils were selected
for this evaluation. Three of these were...
