Determination Of Chilling Requirement Of Arkansas Thornless Blackberry Cultivars, Chrislyn A. Drake, John R. Clark
Determination Of Chilling Requirement Of Arkansas Thornless Blackberry Cultivars, Chrislyn A. Drake, John R. Clark
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Little research has been done to determine the chilling requirement for blackberry cultivars. However, field observations from areas where fewer hours of chilling occur indicate that ‘Navaho’ requires more hours of chilling than does ‘Arapaho’. The objective of our study was to determine a method for measuring the chilling requirement using whole plants of two blackberry cultivars, Arapaho and Navaho. One-year old, bare-root plants were field-dug on 26 October 1999 and placed in a cold chamber at 3ºC. Ten single-plant replications of each cultivar were removed at 100-hour intervals up to 1000 hours. The plants were potted and placed in …

Optical Transmittance Of A Rice Leaf Via Ray Tracing, Stephen Nicoletti, Alois (Al) J. Adams
Optical Transmittance Of A Rice Leaf Via Ray Tracing, Stephen Nicoletti, Alois (Al) J. Adams
Journal of the Arkansas Academy of Science
Optical reflectance from a plant leaf increases in response to stress and disease. Previous studies at the University of Arkansas at Little Rock found that, while the reflectance from a rice leaf increased with increased salinity, reflectance changes could not be used to differentiate one stress or disease from another. The objective of this study is to characterize the angular distribution of optical transmittance for a healthy rice leaf using a ray tracing technique and assuming a three-media optical model. The ultimate goal is to relate this distribution to specific plant pathologies. Three rays are traced through the cross section …
Floristic Status Of Log Ferns (Dryopteris) In Arkansas, James H. Peck
Floristic Status Of Log Ferns (Dryopteris) In Arkansas, James H. Peck
Journal of the Arkansas Academy of Science
The fern flora of Arkansas consists of 96 taxa, including five species and three hybrids of the Log Fern genus Dryopteri This report summarizes a twenty year floristic and ecologic study of their distribution and abundance in Arkansas. Historica data are presented to review the slow accumulation of taxa reported in floras of Arkansas from early collectors to 1980 and the rapid accumulation of taxa since 1980 employing modern field techniques. Chorological data and floristic data are presented based on field, herbarium, and literature studies to correct the record and document the known localities of the eight Arkansas taxa: Dryopteris …

Characteristics Of Some Fruiting Plant Species In Northwest Arkansas, And The Avian Assemblages That Feed On Them, John W. Prather, Kimberly G. Smith, Michael A. Mlodinow, Cecilia M. Riley
Journal of the Arkansas Academy of Science
Fruits continue to be recognized as an important food source for birds in temperate areas, particularly during the fall migration period. More than 20 species of plants producing fleshy fruits are found in the Arkansas Ozarks. However, only a few of these appear to be important resources for birds during the fall migration period (August - October). Among those are sassafras (Sassafras albidum), gray-backed grape (Vitis cinerea), black cherry (Prunus serotina), hercules club (Araliaspinosa) and pokeweed (Phytolacca americana). Over the past 4 years, we have documented the physical and nutritional characteristics of those fruits and taken observational data on the …
