In Vitro Production Protocol Of Vaccinium Uliginosum L. (Bog Bilberry)Growing In The Turkish Flora, Mustafa Cüce, Atalay Sökmen

Turkish Journal of Agriculture and Forestry

This novel approach was designed to increase the production capacity of Vaccinium uliginosum L. via direct organogenesis. Lateral buds containing one or two leaves were initially cultured in McCown woody plant medium (WPM), Anderson's rhododendron medium, and Murashige and Skoog basal media, each supplemented with zeatin/indole-3-butyric acid (IBA) and zeatin/naphthalene acetic acid (NAA) (1.0/0.1 mg L-1). WPM containing the zeatin/IBA combination was the most effective as the basal medium. Various plant growth regulators (PGRs) were then investigated for the best shoot multiplication, and zeatin was found to be most favorable PGR in all cases. The highest shoot length and shoot …

Influence Of Vermicompost Application On Soil Consistency Limits And Soil Compactibility, Serdar Sari, Ekrem Lütfi̇ Aksakal, İlker Angin

Turkish Journal of Agriculture and Forestry

Soil organic matter (SOM) is a composite indicator of soil quality. Recycling of organic wastes is one of the environmentally compatible and economically viable options to increase and/or maintain SOM content. Our study was conducted to evaluate the effects of vermicompost (0%, 0.5%, 1%, 2%, and 4% w/w) on the consistency limits and the Proctor compaction test parameters of three texturally different soils (sandy loam, loam, and clay) from similar climatic conditions and cropping management practices. Results showed that vermicompost increased the optimum moisture content (OMC) with an associated decrease in maximum dry soil bulk density (MBD). The increase in …

Response Of Five Triticale Genotypes To Salt Stress In In Vitro Culture, İsmai̇l Bezi̇rğanoğlu

Turkish Journal of Agriculture and Forestry

Salinity is one of the important abiotic stresses that restrict plant development. Triticale is a highly adaptable crop, known for its high-quality grain, yield potential, and resistance to disease. Responses of five cultivated genotypes (Ümran Hanım, Mikham 2002, Melez 2001, Tatlıcak, and Alper Bey) of triticale to salt stress were tested in callus and embryogenic callus formation in this study. Cotyledon explants were selected as explants for callus induction and embryogenic callus formation. The five tested triticale genotypes varied in their callus growth and embryogenic callus formation. Ümran Hanım, Tatlıcak, and Alper Bey were observed for better callus induction; similarly, …

Turkish Journal of Agriculture and Forestry

Changes in chemical composition and quality traits of carrot roots (Daucus carota L.) grown in organic (ORG) and integrated (INT) farming systems were investigated during two successive years. Three carrot cultivars (Fanal, Rodelika, and Rolanka) were included. Determinations of sugars, organic acids, α- and ß-carotene, and vitamin C were performed with an HPLC system, and a liquid chromatography-mass spectrometry (LC-MS) system was used for the identification and quantification of phenolics. A higher yield of carrot in the ORG system was observed (42-44 t ha-1) as compared with the INT system (37-40 t ha-1). The impact of farming system on morphometric …

Turkish Journal of Biology

Given the importance of borage (Borago officinalis L.) as a medicinal herb, androgenic studies are necessary in order to speed up the breeding programs of this plant species. In this work, we evaluated the effect of silver nitrate, activated charcoal, ascorbic acid, and polyvinylpyrrolidone (PVP), previously described as antibrowning agents and promoters of androgenesis. Adding silver nitrate at a concentration of 5 mg L-1 significantly enhanced the androgenic responses of cultured anthers up to ~2-fold for total calli production (53.33%) and up to ~2.5-fold for embryonic calli and embryo formation (30% and 0.3 embryos/anther, respectively) compared to control culture medium. …

What Do Undergraduate Students Know About Scholarly Communication? A Mixed Methods Study, Catherine Fraser Riehle, Merinda Kaye Hensley

University of Nebraska-Lincoln Libraries: Faculty Publications

Amid movements that recognize undergraduate students as knowledge creators, transformative work is being done at the intersection of information literacy and scholarly communication. Absent from the literature so far is research related to students’ perception and understanding of scholarly communication. This paper reports a mixed methods study at two major research universities in the United States, where undergraduate student researchers were surveyed and interviewed about their scholarly communication practices and perceptions. This work informs development of programming at the intersection of scholarly communication and information literacy in general, and for those involved with undergraduate research experiences in particular.
