A New Species Of Silene (Caryophyllaceae) From East Anatolia (Turkey): Silene Gevasica Hamzaoğlu Sp. Nova, Ergi̇n Hamzaoğlu, Murat Koç, Ümi̇t Budak
Turkish Journal of Botany
Silene gevasica Hamzaoğlu sp. nova is described as a new species from Gevaş district (Van province). The specimen was collected from calcareous rocks, at an altitude between 2100 and 2200 m from Artos mountain. The new species is similar to Silene araratica Schischk. The differences between these 2 taxa are discussed.
Population Dynamics Of Parthenium Hysterophorus (Asteraceae) And Its Biological Suppression Through Cassia Occidentalis (Caesalpiniaceae), Jai Knox, Disha Jaggi, Manoj Stephen Paul
Turkish Journal of Botany
Phytosociological analysis performed over 2005 to 2009 revealed that Cassia occidentalis L. is a dominant species at 3 of 4 sites in Agra district, India, that were previously observed to be dominated by heavy populations of Parthenium hysterophorus L. In order to determine the role of biomolecular interaction, i.e. the allelopathic effect, if any, on this shift of floral pattern effects, aqueous shoot and root cold leachates were determined on seed germination, shoot cut bioassay, seedling bioassay, chlorophyll, nitrogen, and protein content of P. hysterophorus. A significant reduction in germination percentage, shoot cut bioassay, seedling bioassay, and chlorophyll of P. …

The Revision Of The Genus Fritillaria L. (Liliaceae) In The Mediterranean Region (Turkey), Mehtap Tekşen, Zeki̇ Aytaç
Turkish Journal of Botany
This paper presents a systematic revision of Fritillaria L. (Liliaceae) in the Mediterranean region of Turkey. The genus used to contain 22 taxa in the Mediterranean region, but in this study it has been evaluated on the basis of 23 taxa. We concluded that F. armena Boiss. and F. zagrica Stapf are synonyms of F. pinardii Boiss. Phylogenetic orders of F. forbesii Rix and F. kittaniae Sorger in the Flora of Turkey were changed. F. crassifolia Boiss. & Huet. subsp. crassifolia was suggested as an Irano-Turanian element. Red list categories of endemic taxa of Mediterranean Fritillaria were revised according to …

Turkish Journal of Botany
In this study, the roots of Viburnum punctatum Buch.-Ham. ex D.Don, Viburnum coriaceum Blume, and Viburnum erubescens Wall. ex DC. were collected from the Nilgiri and Coimbatore hills in Tamil Nadu, India. Transverse sections of plant roots were prepared with the aid of a rotary microtome. The sections, each at a thickness of 10 µm, were stained and fixed in Canada balsam and the morphoanatomical features of each specimen were noted. The specimens were powdered using a mechanical grinder and were mounted in suitable media for starch grains, sclereids, druses, fibres, and vessels. Morphoanatomical features of diagnostic importance were recorded …

Comparison Of Growing Media For Container Grown Plants, Paul Harris, David Longer, Derrick Oosterhuis, Dimitra Loka
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Greenhouse and growth chamber experiments are conducted worldwide in efforts to produce solutions that would increase yields of agronomic crops. However, the results of those experiments vary due to the many growth media being used. An experiment was conducted in the fall of 2010 to identify a broadly acceptable growth media that would produce uniform stands and optimum results in greenhouse and growth chamber settings. A total of six growth media were tested on cotton (Gossypium hirsutum) at the Arkansas Agricutural Research and Extension Center’s Altheimer Lab in Fayetteville. The plants grown in each medium were harvested six weeks after …

Active canopy sensors are currently being studied as a tool to assess crop N status and direct in-season N applications. The objective of this study was to use a variety of strategies to evaluate the capability of an active sensor and a wide-band aerial image to estimate surface soil organic matter (OM). Grid soil samples, active sensor reflectance and bare soil aerial images were obtained from six fields in central Nebraska before the 2007 and 2008 growing seasons. Six different strategies to predict OM were developed and tested by dividing samples randomly into calibration and validation datasets. Strategies included uniform, …

Soil Fertility And Crop Yields In Long-Term Organic And Conventional Cropping Systems In Eastern Nebraska, Samuel E. Wortman, Tomie D. Galusha, Stephen C. Mason, Charles A. Francis
Department of Agronomy and Horticulture: Faculty Publications
Organic agriculture aims to build soil quality and provide long-term benefits to people and the environment; however, organic practices may reduce crop yields. This long-term study near Mead, NE was conducted to determine differences in soil fertility and crop yields among conventional and organic cropping systems between 1996 and 2007. The conventional system (CR) consisted of corn (Zea mays L.) or sorghum (Sorghum bicolor (L.) Moench)–soybean (Glycine max (L.) Merr.)–sorghum or corn–soybean, whereas the diversified conventional system (DIR) consisted of corn or sorghum– sorghum or corn–soybean–winter wheat (wheat, Triticum aestivum L.). The animal manure-based organic system (OAM) …

The soybean cyst nematode (SCN; Heterodera glycines Ichinohe) is the most economically important soybean [Glycine max (L.) Merr.] pathogen in the United States. Field SCN populations are adapting to the narrowly based SCN resistance currently deployed in soybean cultivars. The objective of our research was to measure the effects of combinations of SCN resistance genes or quantitative trait loci (QTL) from the wild soybean (Glycine soja Siebold & Zucc.) PI 468916 and the domesticated soybean accessions PI 88788 and PI 437654. Two populations were developed to test the combinations of QTL and genes. Both populations segregated for the …

Moving Micronutrients From The Soil To The Seeds: Genes And Physiological Processes From A Biofortification Perspective, Brian M. Waters, Renuka P. Sankaran
Department of Agronomy and Horticulture: Faculty Publications
The micronutrients iron (Fe), zinc (Zn), and copper (Cu) are essential for plants and the humans and animals that consume plants. Increasing the micronutrient density of staple crops, or biofortification, will greatly improve human nutrition on a global scale. This review discusses the processes and genes needed to translocate micronutrients through the plant to the developing seeds, and potential strategies for developing biofortified crops.

Turkish Journal of Botany
This study reports, for the first time, an efficient in vitro plant regeneration protocol for Digitalis lamarckii Ivan. (dwarf foxglove) via direct shoot organogenesis. Two sets of experiments were carried out; the first compared different concentrations of 6-benzylaminopurine (BAP), kinetin, thidiazuron (TDZ), and zeatin alone using leaf explants excised from in vitro germinated seedlings, while the second set tested the combinations of indole-3-butyric acid (IBA) with BAP, kinetin, TDZ, and zeatin for shoot multiplication from the leaf explants, which were already cultured and developed numerous shoots during the first set of experiments. For shoot regeneration (the first set of experiments), …

Artemisia lancea Vaniot, A. argyi H.Lév. & Vaniot, and A. lavandulaefolia DC., all native from eastern Asia, are reported as new alien taxa from Romania. A. lancea has not been recorded so far in Europe, while A. argyi and A. lavandulaefolia are naturalised in the European part of the former USSR. All 3 species were collected in the Socola railway yard in northeastern Romania; the specimens were deposited in the IASI Herbarium, at the University of Agricultural Sciences and Veterinary Medicine Iaşi. Their introduction was accidental, through the rail transport from the former USSR. The 3 species are perennial herbs, …
