Turkish Journal of Agriculture and Forestry
Iron is one of the most important elements in plant mineral nutrition. Fe deficiency is a critical abiotic stress factor for Mediterranean citriculture; the development of marker-assisted selection for this trait would greatly enhance rootstock breeding. In this study, DNA sequencing and single-stranded conformation polymorphism (SSCP) analyses were performed to determine the allelic diversity of genes associated with tolerance to iron chlorosis in citrus. Two candidate iron chlorosis tolerance genes were selected from existing Citrus EST databases and Arabidopsis thaliana genome databases. Ferritin-3 chloroplast precursor and putative membrane transporter candidate gene sequences were used to define primers in conserved regions. …

Hygienic Condition Of Maize Silage (Zea Mays L.) Depending On Cutting Height And Ensiling Additive, Grazyna Szymanska, Hanna Sulewska, Marek Selwet
Turkish Journal of Agriculture and Forestry
Maize silage is a high energy bulk feed, extensively used in the nutrition of dairy and meat purpose cattle due to the high yielding potential of this crop, high concentration of energy, palatability, and easy application in the total mixed ration feeding regime. A necessary precondition for the complete utilization of the nutritive value of maize is to prepare high quality silage. In North America and Europe, cattle nutrition is increasingly based on maize silage fed throughout the year, resulting in the need to store silage in silos for 14 months or even longer. Thus, it is necessary to collect …
The Effect Of Ultrastructure And Moisture Content On Mechanical Parameters Of Pine Wood (Pinus Sylvestris L.) Upon Tensile Stress Along The Grains, Edward Roszyk
Turkish Journal of Agriculture and Forestry
Selected mechanical parameters of earlywood and latewood from Pinus sylvestris subjected to tensile stress were measured as a function of moisture content. Microfibril angles (MFAs) to the longitudinal axis of the cell in the S2 layer of tangent cell walls in the same wood samples were also measured. The tensile strength and modulus of elasticity of earlywood were practically independent of its moisture content, while the same parameters of latewood significantly decreased as its moisture content increased in the hygroscopic range. For earlywood, the strain at break was greater the higher its moisture content. For latewood, no notable effect of …

Turkish Journal of Agriculture and Forestry
Sesame (Sesamum indicum L.) is an important oilseed crop with high-quality seed oil and many antioxidant properties. Owing to its commercial and medicinal values, there is a renewed interest among agricultural scientists in this ancient crop. Efforts to strengthen the sesame-specific marker base have been initiated in the recent past; however, the available number of microsatellite markers is still not sufficient for the development of high-resolution genetic linkage maps for important agronomic traits and there is a need to increase the number of informative DNA markers in sesame. In the present study, we developed 25 microsatellite markers by employing the …

Turkish Journal of Agriculture and Forestry
The normalized difference vegetation index (NDVI) is gaining popularity as a complementary selection tool, even though it requires an instrument not readily available in the developing world. We evaluated several parameters (originating from the analysis of digital photos using BreedPix software) as potential selection criteria in 23 winter wheat yield trials grown over 4 years at 2 sites. NDVI and digital photos were taken at key development stages from stem elongation to maturity. The correlations between digital photo parameters a and u and grain yield, as well as correlations between NDVI and grain yield within individual trials, varied depending on …

Smart Biologics For Crop Protection In Agricultural Systems, Ömür Baysal, Mahmut Tör
Turkish Journal of Agriculture and Forestry
Crop losses caused by insects, pests, and pathogens remain one of the major problems in sustainable agriculture. Environmental and health concerns regarding the overuse of pesticides, and the impacts of climate change on epidemics are immediate pressing issues. In addition, the breakdown of plant resistance by pathogen populations brings limitations to the genetic control of diseases. Biologics can be effective in all types of agricultural systems including organic, sustainable, and conventional. Beneficial microorganisms including Bacillus and Trichoderma species have been employed as environmentally safe biopesticides. Molecular and proteomic studies on biopesticides have revealed the nature of antibiotics, secreted enzymes, and …

The Application For Fertilizer-Yield Relationships Of The Et-Yield Response Factor Equation, Ahmet Ertek
Turkish Journal of Agriculture and Forestry
Many attempts have been made to understand the plant response to water using plant growth models. The effects of fertilizer on crop yield are greater than those of water. Therefore, some models that have been developed for the evaluation of water-yield relationships can also be used for fertilizer-yield relationships. The purpose of this study was to develop an equation to use in fertilizer applications similar to one used to evaluate crop production under adequate and deficit water supply regimes. The equation can be rewritten for the fertilizer consumed by plants instead of the evapotranspiration (ET). Sample applications showed that the …

Faculty Publications
Despite concerns that the Louisiana Pine Snake (Pituophis ruthveni) has been extirpated from large portions of its historic range, only a limited number of studies on their movement patterns have been published. Winter movement patterns are of particular interest since it has been hypothesized that impacts of management practices would be reduced during the winter. Using radiotelemetry, we determined winter movement patterns of Louisiana Pine Snakes (11 males, 8 females) in 5 study areas (2 in Louisiana and 3 in Texas). Movements during winter (November–February) were greatly curtailed compared to the remainder of the year; however, snakes occasionally undertook substantial …

The effects of forest management on soil carbon (C) and nitrogen (N) dynamics vary by harvest type and species. We simulated long-term effects of bole-only harvesting of aspen (Populus tremuloides) on stand productivity and interaction of CN cycles with a multiple model approach. Five models, Biome-BGC, CENTURY, FORECAST, LANDIS-II with Century-based soil dynamics, and PnET-CN, were run for 350 years with seven harvesting events on nutrient-poor, sandy soils representing northwestern Wisconsin, USA. Twenty CN state and flux variables were summarized from the models' outputs, and statistically analyzed using ordination and variance analysis methods. The multiple models' averages suggest that bole-only …

Increased wildfires and temperatures due to climate change are expected to have profound effects on forest productivity and nitrogen (N) cycling. Forecasts about how wildfire and climate change will affect forests seldom consider N availability, which may limit forest response to climate change, particularly in fire-prone landscapes. The overall objective of this study was to examine how wildfire and climate change affect long-term mineral N availability in a fire-prone landscape. We employed a commonly used landscape simulation model (LANDIS-II) in the New Jersey Pine Barrens, a landscape characterized by frequent small fires and fire-resilient vegetation. We found that fire had …
