Granite rocks of the Sierra Nevada batholith underlie the study area. The eastern watershed of Owens Peak is botanically diverse, with 64 families, 230 genera, and 440 taxa currently documented. Floristic elements within the study area include the southern Sierra Nevada, Great Basin, and Mojave Desert. The flora previously was poorly documented, as discovered …
Cantua Dendritica (Polemoniaceae), A New Species From Peru, And Two New Cantua Names, J. Mark Porter, L. Alan Prather
Cantua Dendritica (Polemoniaceae), A New Species From Peru, And Two New Cantua Names, J. Mark Porter, L. Alan Prather
Aliso: A Journal of Systematic and Floristic Botany
Cantua dendritica is described as new. This species is apparently restricted to the region around Paucartambo, Department of Cusco, Peru. Related to, and frequently identified as, Cantua flexuosa, this new species differs in its glandular calyx, highly branched trichomes on the margin of the corolla lobes, and its softly herbaceous, glandular pilose leaves. In addition, two new names are proposed in Cantua for the two species of Huthia that have been transferred to Cantua, C. volcanica (formerly Huthia caerulea), and C. mediamnis (formerly H. longiflora).

Effects Of Storage Temperature And Duration On The Milling Properties Of Rice, Tanya Pereira, Nora Cooper, Terry Siebenmorgen
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
To maximize rice quality, it is essential to quantify the various factors that affect milling properties of rice. Rice aging, a process during which rice undergoes a series of chemical and physicochemical changes, affects head rice yield (HRY) and the rate at which HRY changes with degree of milling (DOM). This study examined effects of storage duration (0, 2, and 4 months) and storage temperature (4, 21, and 35°C) on milling properties of ‘Wells’ (long-grain) and ‘Jupiter’ (medium-grain) rice cultivars. In general, HRY increased with storage duration, most significantly for Wells cultivar. Millability curves were developed by plotting HRY vs. …

Geographic Variation In The Pollination Biology Of Passiflora Lutea (Passifloraceae), J. Burks Holland, J. Lanza
Geographic Variation In The Pollination Biology Of Passiflora Lutea (Passifloraceae), J. Burks Holland, J. Lanza
Journal of the Arkansas Academy of Science
Like most species of Passiflora, P. lutea is reported to produce one-day flowers with complicated floral movements and requires deposition of non-self pollen for fruit production. Medium sized bees are the most likely pollinators in central Texas. We report on a series of observations and experimental manipulations that compare the reproductive biology of P. lutea in central Arkansas to that reported previously from plants about 800 km distant in central Texas. We observed floral movements and floral visitors, compared fruit production of flowers available to pollinators versus flowers from which pollinators were excluded, and compared fruit production of flowers that …
Algae In Agricultural Fields From St. Francis County, Arkansas, T. Smith
Algae In Agricultural Fields From St. Francis County, Arkansas, T. Smith
Journal of the Arkansas Academy of Science
On August 9th, 2007, two agriculture fields (rice and sorghum fields) were sampled for freshwater algae in St. Francis County. The purpose of this study was to document the algal species in the rice and sorghum fields and compare the similarities of species composition. There were a total of 53 species identified. Overall, diatoms and cyanobacteria were equally dominant with both represented by 21 species (39.6% of the total) and 11 green algal species (20.8%) were present. The sorghum field was dominated by Chlorogloeopsis fritschii and Chroococcus limneticus, while Anabeana cylindrica was abundant in the rice field.
Physicochemical Properties And Fungitoxicity Of The Essential Oil Of Citrus Medica L. Against Groundnut Storage Fungi, Emmanuel Peter Essien, Joseph Peter Essien, Basil Nse Ita, Godwin Asukwo Ebong
Physicochemical Properties And Fungitoxicity Of The Essential Oil Of Citrus Medica L. Against Groundnut Storage Fungi, Emmanuel Peter Essien, Joseph Peter Essien, Basil Nse Ita, Godwin Asukwo Ebong
Turkish Journal of Botany
The in vitro antifungal effect of the essential oil of Citrus medica L. on storage fungi of Arachis hypogea L. stored for 6 months was evaluated using the disc diffusion agar method. The oil exhibited a wide spectrum of fungitoxicity, inhibiting all 14 fungus species tested. Thus, the oil can be exploited as a fumigant against storage fungi for the preservation of stored legume seeds due to its wide range of activity, non-phytotoxicity, and long-term persistence of fungitoxicity.

Theodor Von Heldreich (1822-1902) And His Turkish Collections, Asuman Baytop, Kit Tan
Turkish Journal of Botany
The distinguished German botanist Theodor von Heldreich (1822-1902) visited Anatolia on at least 6 separate occasions as documented by specimens cited in Flora of Turkey and Flora Orientalis. His first visit was in 1845 and his last, to İzmir, in 1852. Within this period of less than seven years he collected c. 3000 sets of specimens. They included the types of nearly 200 new taxa and, if including syntypes and lectotypes, the figure is 207. The majority stem from the first expedition of 1845. The non-type specimens cited in the Flora are 280. It is difficult to trace Heldreich´s itinerary …

An Acreage Response Model For Arkansas Rice Farms, J. Grant Ballard, Michael R. Thomsen
An Acreage Response Model For Arkansas Rice Farms, J. Grant Ballard, Michael R. Thomsen
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
In recent years, market forces have signaled a strong demand for rice as well as other Arkansas crops. However, high fuel, fertilizer, and chemical costs have negatively impacted farm income, and these input costs are widely known to impact planting decisions of farmers. The goal of this study is to develop and estimate an acreage response model for rice. The model is used to compute acreage response elasticities and provides insight into roles that input costs and crop prices play in acreage decisions made by producers. Economic theory predicts that prices for important inputs such as fuels and fertilizers as …

The Effect Of Austrian Winter-Pea Cover Crop And Cow-Pea Companion Crop On Corn Yield, Matthew Marsh, David Longer, Vaughn Skinner
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Leguminous cover crops have the potential to combat the rising input cost of commercial nitrogen (N) fertilizers. This experiment examines benefits of implementing a leguminous cover and/or companion crop into a corn production system. Legumes biologically fix nitrogen from the atmosphere, adding to the nitrogen content of the soil. In this experiment Austrian winter peas (Pisum arvense) (AWP) were used as the leguminous cover crop and cowpeas (Vigna unguiculata) were used as the companion crop. A two year experiment was carried out in which winter peas were planted on half the field in the fall and allowed to grow until …
Subcritical Water And Carbonated Water Extraction Of Anthocyanins From Grape Pomace, Lydia Rice, L. R. Howard
Subcritical Water And Carbonated Water Extraction Of Anthocyanins From Grape Pomace, Lydia Rice, L. R. Howard
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Grape pomace, a by-product of juice and wine processing, is a rich source of anthocyanins, antioxidant compounds that may afford protection against cancer and coronary heart disease. Unfortunately, traditional extraction of these antioxidants involves use of organic solvents, which pose serious safety and disposal problems for industry. Clearly a need exists for “green” extraction technologies—such as use of subcritical water—that eliminate or reduce the amount of organic solvents. In this study, we determined the efficacy of subcritical and carbonated water in extraction of anthocyanins from red grape pomace. Extraction variables including particle size, pomace mass, and temperature were optimized, and …

Investigating The Utilization Of Silica Gel Packets In Drying Research-Scale Rough Rice Samples, Ashley Wiedower, George Ondier, Terry Siebenmorgen
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Rice moisture content (MC) must be reduced to approximately 12.5% MC to prevent spoilage during storage. Desiccants may provide an improved method for drying research-scale rice samples. This study investigated the effects of 1) rice mass to be dried, 2) placement method of silica gel packets in rice samples, 3) regeneration and re-use of the packets, 4) drying temperature, and 5) initial MC on the effectiveness of silica gel packets to dry rough rice samples to the desired 12.5% MC. Multiple masses (200, 500, and 1000 g) of long-grain rice samples were dried using three desiccant placement treatments: 1) intimate …

Desert Rocks – A Habitat Which Supports Many Species That Were New To Science In The Last 40 Years, Avinoam Danin
Turkish Journal of Botany
Hard limestone, dolomite, sandstone, and granite constitute, under certain conditions, smooth-faced outcrops in desert areas of SW Asia. This habitat supports the most rare plant species in the desert including most of the desert endemics of Israel, Sinai, and Jordan. The smooth-faced outcrops efficiently contribute runoff water to the rock crevices and events when water is available for plant utilisation take place at a higher frequency than in the other habitats in the desert. In many sites plants are isolated and protected by impermeable rocks from competition from other plants. The rare and special plants found in this habitat include …
15n Effects On Chlamydomonas Reinhardtii, Ryan Geraets, Brett Kollars
15n Effects On Chlamydomonas Reinhardtii, Ryan Geraets, Brett Kollars
The Journal of Undergraduate Research
Non-radioactive isotopic labeling has become a regular technique for efficiently labeling a wide range of macromolecules. The overall goal for this project was to develop a method of globally measuring plant protein turnover rates. In order to do so, an isotopic labeled environment that does not induce stress had to be used. The objective of this particular segment of research was to develop a 15N-labeled Tris-Acetate-Phosphate (TAP) media in which Chlamydomonas reinhardtii can successfully grow without eliciting stressed physiological responses. Our results illustrate that we have successfully developed 15N-labeled TAP that does not stress Chlamydomonas reinhardtii.

Effects Of Deuterium On Chlamydomonas Reinhardtii, Brett Kollars, Ryan Geraets
The Journal of Undergraduate Research
In order to develop software tools to monitor rates of total protein turnover in plants, attempts were made to maximally label all the proteins in vivo. Our study focused on the use of the stable isotope of hydrogen, deuterium, to label proteins of C. reinhardtii. The goal of this study was to determine the effect of the label on algal growth. C. reinhardtii is a unicellular green algae that is heterotrophic, photoautotrophic and mixotrophic. The results showed that increasing concentrations of deuterium in the algal growth medium had a negative effect on the growth of the algae. These preliminary results …

The Effects Of Ultraviolet Radiation On The Contents Of Chlorophyll, Flavonoid, Anthocyanin And Proline In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari
The Effects Of Ultraviolet Radiation On The Contents Of Chlorophyll, Flavonoid, Anthocyanin And Proline In Capsicum Annuum L., Kobra Mahdavian, M. Ghorbanli, Khosrow Manochehri Kalantari
Turkish Journal of Botany
Although ultraviolet radiation is potentially harmful, it is an important component of terrestrial radiation to which plants have been exposed since invading land. Since then, plants have evolved mechanisms to avoid and repair UV radiation damage. Therefore, it is not surprising that photomorphogenic responses to UV-B and UV-C are often assumed to be adaptations to harmful radiation. Most of the compounds accumulated are directly involved in UV-B and UV-C protection: they are either efficient in filtering excess radiation or in scavenging radicals. In this study plants were grown for 5 weeks in controlled environment room. The plants were grown in …
