The Influence Of Poultry Litter Biochar On Early Season Cotton Growth, Taylor D. Coomer, David E. Longer, Derrick M. Oosterhuis, Dimitra A. Loka
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Cotton is known for being sensitive to cool, wet soils, especially in the early stages of growth. Amendments to soil can aid cotton seedlings in development and nutrient uptake. However, soil amendments can be costly and detrimental to the environment, and alternatives such as the addition of biochar have been considered. Biochar is produced from biomass that has gone through pyrolysis and has been shown to improve plant yield, microbial response, soil structure, soil cation–exchange capacity, and water use efficiency. This study was conducted to evaluate the effect of biochar on early season cotton growth. The aim of this study …

Morphology, Structure, Function And Evolution Of Infrastaminal Scales In Cuscuta (Convolvulaceae), Stephanie Riviere
Theses and Dissertations (Comprehensive)
Cuscuta (dodder, Convolvulaceae) is a genus of about 200 species of obligate stem parasites of cosmopolitan distribution. Infrastaminal scales (IFS) are staminode-like formations that surround the ovary in the flowers of dodders. Their morphological diversity has historically provided some of the most useful taxonomic diagnostic characters at the species-level, however, their function had not been determined. I performed a comparative study of the IFS in 147 taxa using light, scanning and transmission electron microscopy, and results were analyzed in relation to a Cuscuta phylogeny obtained from a combined analysis of rbcL and 26S rDNA gene sequences. To test the hypothesis …

Turkish Journal of Botany
The leaf epidermis of 14 Onosma L. species was examined by light and scanning electron microscopy (SEM). The leaf characters studied showed some variations. Morphologic features of the epidermal cells such as shape, structure of the anticlinal walls, stomatal size, outer stomatal rims, peristomatal rims, and apertures were summarised in the examined taxa. It was found that these characters are variable in the genus but usually they are stable within a species. Epidermal cells of the investigated taxa are polygonal, elongated, or irregular. Anticlinal walls of the epidermal cells are generally straight to curved and repand. Apertures are long, ellipsoidal, …
Comparative Morphological, Epidermal, And Anatomical Studies Of Pinus Roxburghii Needles At Different Altitudes In The North-West Indian Himalayas, Satyendra Prakash Tiwari, Pradeep Kumar, Deepika Yadav, Devendra Kumar Chauhan
Turkish Journal of Botany
The aim of the present study was to understand the ecological adaptation of Pinus roxburghii Sarg. in the North-West Himalayan region. P. roxburghii needles showed morphological, epidermal, and anatomical variation at different altitudes. Needle length was negatively correlated with altitude. Stomatal characters like stomatal density, stomatal index, and guard cell lengths were found to be affected by environmental factors and showed a direct correlation with altitude. The results showed that potential conductance index was dependent on the climatic conditions of the habitat. The anatomical properties of needles exhibited variation from lower to higher elevation, especially in the number and position …

Size-Fractionated Phytoplankton And Nutrient Dynamics In The Inner Part Of İzmir Bay, Eastern Aegean Sea, Serkan Kükrer, Hasan Baha Büyükişik
Turkish Journal of Botany
İzmir Bay has been one of most polluted bays of the Mediterranean for a long time. When the 'Big Channel Project' was completed in 2000, sewage flow into the bay ended. Hence, the influence of creeks, which are the only source of water transportation to the inner bay, was investigated in the current study. Monthly samples of creek water and seawater were taken. Basic water quality variables and nutrients were measured. In addition, the phytoplankton community was arrayed into size fractions to assess the contribution of each size fraction to biomass and pigment concentrations. Analyses showed that the creek waters …

Turkish Journal of Botany
Deserts comprise about 95% of the total land surface of Egypt; therefore, their potential for production must be assessed. Weed communities are mainly affected by the environment, and studies may increase our knowledge of the relationship among the weed flora, soil properties, crop rotation, soil management, fertiliser usage, and weed control. The area under study is one of the most recently reclaimed lands. The recorded 150 species in the monitored 19 sites were distributed within 33 families. The species-rich families were: Poaceae (31), Asteraceae (23), Brassicaceae (13), Chenopodiaceae (12), and Fabaceae (12). Chorological analysis revealed that the widely distributed species …

Vegetation And Soil Relationships In The Inland Wadi Ecosystem Of Central Eastern Desert, Egypt, Fawzy Salama, Monier Abd El-Ghani, Noha El-Tayeh
Turkish Journal of Botany
In January 2010, torrential rains that had suddenly swept away a limited area in the Eastern Desert facing Qena Province in Upper Egypt resulted in the enriching of the vegetation of some extremely dry wadis at this location. A vegetation survey carried out shortly after this event, in April, revealed the prevalence of annuals in considerable abundance, which are hardly recognisable in such usually dry habitats. The normally scarce perennial vegetation had flourished, too. A total of 32 species, 11 annuals, and 21 perennials that belong to 27 genera and 15 families were recorded. The life-form spectrum in the present …
Effects Of Exogenous Methyl Jasmonate And 2-Isopentenyladenine On Artemisinin Production And Gene Expression In Artemisia Annua, Mahboobeh Zare Mehrjerdi, Mohammad Reza Bihamta, Mansoor Omidi, Mohammad Reza Naghavi, Hassan Soltanloo, Mojtaba Ranjbar
Turkish Journal of Botany
Artemisinin, produced in very low amounts in Artemisia annua L. plants, is one of the most effective drugs in treating malaria. In this study, the effect of exogenous applications of methyl jasmonate (MeJA) and 2-isopentenyladenine (2-iP) in artemisinin production and the main genes of its biosynthesis pathway within a 1-week time period were investigated. Both MeJA and 2-iP increased artemisinin content, but no correlation was found between gene expression and its content. In plants treated with 2-iP, despite increased gene expression following elicitor application, downregulation of gene expression was also observed, which might be attributed to the negative effects of …

Cadmium-Induced Structural Disturbances In Pisum Sativum Leaves Are Alleviated By Nitric Oxide, Tuan Anh Tran, Valya Vassileva, Petar Petrov, Losanka Petrova Popova
Turkish Journal of Botany
In the present study, the protective effect of nitric oxide (NO) against Cd-induced structural disturbances in pea (Pisum sativum) leaves was investigated. Cadmium treatment resulted in a decreased leaf size and thickness of the lamina, reduced intercellular spaces in the mesophyll, small pavement cells, and a high density of stomata. These abnormalities were partially or fully reversed by a simultaneous application of Cd and the NO donor, sodium nitroprusside (SNP). The concentration of 1000 µM SNP was very effective in counteracting the adverse effects of Cd and resulted in leaf structural parameters close to those of the control leaves. These …

Comparative Anatomy Of Elaiophores And Oil Secretion In The Genus Gomesa (Orchidaceae), Natalia Elva Gomiz, Juan Pablo Torretta, Sandra Silvina Aliscioni
Turkish Journal of Botany
Oils are atypical floral rewards in Orchidaceae and are produced by epidermal glands called elaiophores. Flowers of many members of the subtribe Oncidiinae either produce oil or mimic oil-producing flowers of Malpighiaceae. We focus our research on 3 species of Gomesa, namely, G. flexuosa, G. riograndensis, and G. varicosa in order to investigate the presence of elaiophores, their micromorphology and internal structure, and the process of oil secretion. Elaiophores were located using Sudan III and their internal and external features examined using light and scanning electron microscopy, respectively. The presence of elaiophores was confirmed for regions of calli that are …
