Response of Corn and Palmer amaranth to Mesotrione
Mesotrione is a herbicide used for the selective pre- and post-emergence control of a wide range of broadleaf and grass weeds in corn (Zea mays). It inhibits the enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) which leads to stop biosynthesis of plastoquinone, a key factor in the synthesis of carotenoid pigment. The depletion of carotenoids leading to bleaching symptoms followed by necrosis in sensitive plants. Palmer amaranth (Amaranth Palmeri) is one of the major weeds in corn production system. This study was conducted to test the hypothesis that mesotrione may be effective to control Palmer amaranth and safe for use in corn. Therefore, the objective of this research was to evaluate response of corn and Palmer amaranth to mesotrione. Corn and Palmer amaranth plants were treated with mesotrione at 105 g ai ha-1,and plant survival data was collected at 3 week after application. There was no injury reported to any of the corn plant, and plant survival rate was reported 100%. However, Palmer amaranth plants showed bleaching symptoms followed by necrosis and plant death. Only 12.5% Palmer amaranth plants survived after mesotrione application. These results demonstrated the tolerance of corn and sensitivity of Palmer amaranth to mesotrione
Eva Palmer-Sikelianos Dances Aeschylus: The Politics of Historical Reenactment when Staging the Rites of the Past
Eva Palmer-Sikelianos (1874–1952), along with her husband, the poet Angehlos Sikelianos,
founded the first modern Delphic Festival in 1927 in an effort to revive the Ancient Greek rites that
took place on that spot over 2,500 years before. She invited “overseers of culture” from around
the globe to convene in the holy city of Delphi for a reenactment of the performance of Prometheus
Bound by Aeschylus in the ancient amphitheater, an Olympic-styled athletic contest,
and an exhibition of Greek crafts. This paper explores Palmer-Sikelianos’s choreography, music
and dramaturgy for her reconstructed Prometheus Bound in light of her own research on ancient
Greek culture and our modern theories of historical reenactment. Based on silent film records of
Palmer-Sikelianos’s 1930 festival, her own autobiography, her collaborations with Natalie Barney
on Greek-themed theatricals in the early 1900s, and comparisons to the movement vocabulary
and other contemporary stagings of ancient Greek festivals and sport, I demonstrate how Palmer-
Sikelianos blended the oldest sources on ancient Greek ritual music and dance that she could find
with what she saw as an authentic “spirit” of Greek culture as observed in modern Greek society.
Compared to the Ballets Russes’s reenactment of ancient Greece, Palmer-Sikelianos’s project to
reenact “authentic” Greek theater and choreography illustrates that theories of theatrical historical
reconstruction in the early twentieth century were heavily influenced by contemporary theatrical,
political, and social events. And like the Fokine and Nijinsky models, Palmer-Sikelianos’s staging
redefines ancient dance through the prisms of ancient sources and modern aesthetics

A comparative yield trial with 24 named varieties and numbered selections of potatoes was
conducted at the University of Alaska Fairbanks, Agricultural and Forestry Experiment Station’s
Palmer Research Center during the 1988 growing season. The trial was conducted at the
Matanuska Research Farm, located six miles west of Palmer on Trunk Road. Nonirrigated trials
have been conducted annually since 1982, and irrigated trials started in 1985. Results of previous
trials have been recorded in AFES Circulars 49, 54, 58 and 65. These circulars are available at the
Agricultural and Forestry Experiment Station offices in Fairbanks and Palmer.Introduction -- Matanuska Farm Yield Trials: Cultural Practices - Environmental Conditions, Results and Discussion; Trials at Other Locations in Alaska: General Procedures; Specific Site Information: Ambler, Delta Junction, Kake, Kenai - Soldotna, Kodiak, Kotzebue, Palmer, Pt.

Circular 118
A yield trial comparing 30 cultivars of potatoes
(Solatium tuberosum L.) was conducted during the
1999 growing season at the University of Alaska
Fairbanks, Agricultural and Forestry Experiment
Station’s (AFES) Palmer Research Center,
Matanuska Farm, located six miles west of Palmer,
Alaska. Similar to 1998, this trial included irrigated
but not irrigated treatments. Data from previous
studies has documented the consistent need for irrigation
as well as the magnitude of increases in yield
that can be realized through irrigation

Managing Alaska Soils
This publication is for the gardener who wants to gain a more thorough understanding of soil basics, including soil components, texture, structure, water permeability and chemistry. There is also information on soil fertility and plant nutrients.This publication replaces the following Extension publications: Soil Fundamentals by C.L. Johnson, former Extension Assistant, Palmer Research Station, University of Alaska Fairbanks and Soil Fertility Basics and Soil Sampling and Analysis by J.L. Walworth, former Soil Scientist, Agricultural and Forestry Experiment Station, Palmer Research Center, University of Alaska Fairbanks
Circular 65
A comparative yield trial with thirty-six
named varieties and numbered selections of
potatoes was conducted at the University of
Alaska Fairbanks, Agricultural and Forestry
Experiment Station’s (AFES) Palmer Research
Center during the 1987 growing season. The
trial was conducted at the Matanuska Research
Farm, located 6 miles west o f Palmer on Trunk
Road.
Nonirrigated trials have been conducted
each year beginning in 1982, and irrigated trials
were begun in 1985. Results of previous trials
have been recorded in Circulars 49, 54, and
58, available at the Agricultural and Forestry
Experiment Station offices in Fairbanks and
Palmer. Varieties with a history of commercial
production in the Matanuska Valley (including
'Alaska 114', 'Bakeking', 'Green Mountain',
'Kennebec', and 'Superior') are included and
serve as a comparative base for newly developed
varieties, numbered selections, or older
varieties that heretofore have not been tested at
this location. Varieties that com pare favorably
with the above-listed standards may warrant
some consideration by commercial growers.
Also included in this report are the results
of abbreviated versions of the AFES

individuals and agencies at nine locations
throughout the state.Introduction -- Matanuska Farm Yield Trials: Cultural Practices and Environmental Conditions, Results and Discussion -- Trials at Other Locations in Alaska: General Procedures, Specific Site Information: Ambler, Copper Center, Delta Junction, Fairbanks, Kake, Kenai and Soldotna, Kodiak, Kotzebue, Palmer, Trapper Cree

Chaos and Shadowing Lemma for Autonomous Systems of Infinite Dimensions
For finite-dimensional maps and periodic systems, Palmer rigorously proved
Smale horseshoe theorem using shadowing lemma in 1988. For infinite-dimensional
maps and periodic systems, such a proof was completed by Steinlein and Walther
in 1990, and Henry in 1994. For finite-dimensional autonomous systems, such a
proof was accomplished by Palmer in 1996. For infinite-dimensional autonomous
systems, the current article offers such a proof. First we prove an Inclination
Lemma to set up a coordinate system around a pseudo-orbit. Then we utilize
graph transform and the concept of persistence of invariant manifold, to prove
the existence of a shadowing orbit
