Siberian Elm Responses To Different Culture Conditions Under Short Rotation Forestry In Mediterranean Areas, Ignacio Pérez, Javier Pérez, Juan Carrasco, Pilar Ciria
Siberian Elm Responses To Different Culture Conditions Under Short Rotation Forestry In Mediterranean Areas, Ignacio Pérez, Javier Pérez, Juan Carrasco, Pilar Ciria
Turkish Journal of Agriculture and Forestry
This work explores the possibilities of biomass production, for energy purposes, of Siberian elm in Mediterranean areas, including marginal lands with poor soil and low water availability. To achieve this, the influence of soil type, planting density, and water availability on biomass production were analyzed after the first 3 years of the growing cycle in 2 different locations. Moreover, a method to estimate biomass production as a function of some morphological parameters of the trees, as well as the use of leaf water potential as a good indicator of trees' water status, are discussed. The analysis of parameters having an …

The present study was carried out to determine the effects of methyl jasmonate (MeJA) treatments on the fruit peel color parameters, anthocyanin content, ethylene biosynthesis, phenolic content, and antioxidant capacity of Braeburn apples. Experimental trees were treated with 1120, 2240, or 4480 mg L-1 MeJA at 1- and 2-week intervals between the 105th and 175th days of growth after full bloom. L* and hue decreased linearly with increasing MeJA concentrations in both experimental years. While MeJA treatments did not cause significant changes in chroma, except for in the final harvest in 2010, it decreased chroma values significantly on all sampling …
Influence Of Natural Zeolite On Nitrogen Dynamics In Soil, Stanislav Torma, Jozef Vilcek, Peter Adamisin, Emilia Huttmanova, Ondrej Hronec
Influence Of Natural Zeolite On Nitrogen Dynamics In Soil, Stanislav Torma, Jozef Vilcek, Peter Adamisin, Emilia Huttmanova, Ondrej Hronec
Turkish Journal of Agriculture and Forestry
Sorption of the cations NH_4^+, Al^{3+}, Fe^{2+}, Mn^{2+}, and Mg^{2+} in powdered zeolite and its mixture with soil was monitored. More than 90% of the observed cations were fixed in the zeolite in the first few minutes of the laboratory experiment, which is a very fast speed of sorption, and the ammonia cations reacted fastest. Consequently, the dynamics of the nitrate and ammoniac nitrogen in soil after application of zeolite in different amounts was monitored. A decreased ammonium content was apparent in the variants with zeolite 1 month after zeolite application in comparison with variants without zeolite owing to the …

Modeling Of Rheological Properties Of Mellorine Mix Including Different Oil And Gum Types By Combined Design, Ann, And Anfis Models, Sali̇h Karasu, Mahmut Doğan, Ömer Sai̇d Toker, Erdal Caniyilmaz
Turkish Journal of Agriculture and Forestry
In the present study, the effects of 2 different oil types (soybean and olive oil) and 3 different gums (xanthan gum, sodium alginate, locust bean gum, and their blends) on the rheological and physicochemical properties (pH, titratable acidity, moisture, and color), overrun, melting rate, melting time, and sensory properties of frozen mellorine samples were determined. Apparent viscosity of all mix samples decreased with shear rate, meaning that mellorine mix samples showed shear thinning behavior. Mellorine mix samples showed Ostwald-de Waele flow behavior (R^2 >= 0.9915). Viscous synergy indexes were calculated to determine if the gums had synergic interaction. The viscous …

Turkish Journal of Agriculture and Forestry
Grapevine dieback is an increasing problem in grape vineyards in Algeria. We conducted field surveys each spring between 2006 and 2012 to determine the fungal pathogens associated with grapevine decline in various grape-growing regions. We isolated and identified 3 species of Botryosphaeriaceae (Botryosphaeria dothidea, Diplodia seriata, and Neofusicoccum parvum) from infected wood using a combination of morphological and cultural characters, as well as phylogenetic analyses of ribosomal DNA internal transcribed spacer (ITS) regions and fruiting body. We identified 20 isolates of Diplodia seriata, 13 isolates of Botryosphaeria dothidea, and 7 isolates of Neofusicoccum parvum. Inoculation of grapevine plantlets with the …

Optimization Of Orius Majusculus Release: Photoperiodic Sensitivity At Different Temperatures And Storage Of Diapausing Adults, Şeri̇fe Ünal Bahşi̇, İrfan Tunç
Turkish Journal of Agriculture and Forestry
The photoperiodic sensitivity and storage of Orius majusculus (Reuter) from Antalya was investigated to obtain data for the optimization of its release. In the current study, it was not possible to induce a high (up to 100%) incidence of diapause unless all the nymphal instars and adults were successively exposed (i.e. full exposure) to a short day length (11.5 h) at constant temperatures of 18 and 26 °C, and fluctuating temperatures of 10/26 °C. Hence an intermittent exposure to long day lengths, even for short periods of time (only during instars IVV or adult stage), would avoid a high incidence …
The Choice Of Auxin Analogue For In Vitro Root Induction Influences Post-Induction Root Development In Eucalyptus Grandis, Muhammad Nakhooda, Maria Paula Watt, David Mycock
The Choice Of Auxin Analogue For In Vitro Root Induction Influences Post-Induction Root Development In Eucalyptus Grandis, Muhammad Nakhooda, Maria Paula Watt, David Mycock
Turkish Journal of Agriculture and Forestry
Previous studies on in vitro rooting for improved micropropagation of eucalypts indicated that root graviperception and post-acclimatisation architecture are determined by the relative exogenous auxin analogue and its stability, supplied during the pre-rooting culture stages. The specific roles of indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) in the rooting medium on the in vitro root morphological processes were explored using a good-rooting clone. In vitro rooting percentage was significantly reduced when either of the auxin inhibitors 2,3,5-triiodobenzoic acid (TIBA) and ρ-chlorophenoxyisobutyric acid (PCIB) or the auxin antagonist kinetin was supplied at rooting, with or without exogenous auxin. For all treatments, …

Bioslurry was analyzed for its composition and was applied at the rate of 600 kg ha^{-1} along with 50%, 75%, and 100% of the recommended dose of N fertilizer for the production of okra. Phosphorus and potassium fertilizers were added according to recommended rates …
Hygienic Condition Of Maize Silage (Zea Mays L.) Depending On Cutting Height And Ensiling Additive, Grazyna Szymanska, Hanna Sulewska, Marek Selwet
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 …

Germination And Electrical Conductivity Tests On Artificially Aged Seed Lots Of 2 Wall-Rocket Species, Simona-Laura Lazar, Sara Mira, Doru Pamfil, Juan Bautista Martinez-Laborde
Turkish Journal of Agriculture and Forestry
The aim of this study was to determine whether the loss of germinability and vigour in wall-rocket seed lots was related to electrolyte leakage. Ten seed lots of 2 wall-rocket species (9 of Diplotaxis tenuifolia and one of D. erucoides (Brassicaceae)) were stored at 45 °C and 70% relative humidity and electrolyte leakage was measured using the conductivity test. Small differences in longevity were found among species or seed lots, suggesting that a similar relative longevity might be expected within the genus Diplotaxis after artificial ageing, and that it will be above the average of that found in other species …

Jerusalem artichoke could be an alternative feedstock for bioenergy during times when there are shortages of other raw materials for the ethanol industry. However, insufficient water under rainfed conditions is a major cause of Jerusalem artichoke losses. Genetic variation for drought tolerance is an essential prerequisite for the development of Jerusalem artichoke cultivars with improved drought tolerance. The objectives of this study were to determine the effects of drought stress on tuber dry weight and biomass and to investigate the genotypic variability in Jerusalem artichoke germplasm. The line-source sprinkler technique was used to compare moisture responses of a range of …

Calls for increased interdisciplinary education have led to the development of numerous teaching techniques designed to help teachers provide meaningful experiences for their students. However, methods of guiding teachers in the successful adoption of innovative teaching approaches are not firmly set. This qualitative study sought to better understand how school-based agricultural education teachers decide to adopt or discontinue a teaching innovation when introduced through ready-made lesson plans, which is currently a common practice of teaching method integration in school-based agricultural education (SBAE). Constant comparative analysis unveiled themes within the reactions to the teaching method’s use, as well as how teacher …
