Tolerance Of Brown-Rot And Dry-Rot Fungi To Cca And Acq Wood Preservatives, Coşkun Köse, Sai̇p Nami̇ Kartal
Turkish Journal of Agriculture and Forestry
Copper remains the primary biocide component used today to protect wood. Increased interest in the use of non-arsenic copper-based wood preservatives has also led to increased studies on copper-tolerant decay fungi. Oxalic acid production by brown-rot fungi is proposed as one mechanism of copper tolerance. This study evaluated oxalic acid production and copper losses from ACQ- and CCA-treated Pinus sylvestris L. and Populus × euramericana I 214 wood by brown-rot fungi: Postia placenta, Gloeophyllum trabeum, Tyromyces palustris, and 2 strains of Serpula lacrymans. There was no clear linear correlation among mass losses, oxalic acid production, or copper losses in most …
Certain Physical And Mechanical Properties Of Medium Density Fiberboards Manufactured From Blends Of Corn (Zea Mays Indurata Sturt.) Stalks And Pine (Pinus Nigra) Wood, Mehmet Akgül, Cengi̇z Güler, Yalçin Çöpür
Turkish Journal of Agriculture and Forestry
Corn stalk is a renewable natural resource that currently has limited industrial utilization. The objective of this study was to examine some chemical properties of corn stalk (holocellulose, \alpha-cellulose, lignin and ash content, alcohol-benzene, hot and cold water solubility, and solubility in dilute alkali [1% NaOH]) and to evaluate its suitability for medium-density fiberboard (MDF) production. Panels were produced using mixtures of corn stalk (Zea mays indurata Sturt.) and pine (Turkish Pinus nigra) fibers in various proportions (from 0% to 100%). The panels produced had density levels of 0.6, 0.7, and 0.8 g cm^{-3}. The physical and mechanical properties of …
Effects Of Alternative Spray Programs And Various Combinations Of Green Pruning On Powdery Mildew [Uncinula Necator (Schw.) Burr.] In Karasakız (Kuntra) Grape Cultivar, İsmet Yildirim, Alper Dardeni̇z
Turkish Journal of Agriculture and Forestry
The effects of alternative spray programs, NaHCO_3/K_2SiO_3 + sulphur, KH_2PO_4/di - 1 - p - menthone, and a conventional spray program, penconazole/sulphur, as well as various levels of shoot toppings (to the 1st, 3rd, and 5th buds) on powdery mildew disease [Uncinula necator (Schw.) Burr.] and grape quality were investigated in this study. The study was carried out on grape variety Karasakız (Vitis vinifera L.) during 2003 and 2004 growing seasons. The effectiveness of NaHCO_3/K_2SiO_3 + sulphur, KH_2PO_4/di - 1 - p - menthene alternate spray programs against powdery mildew was found as 74.8% and 70.7% on leaf and 65.7% …
Plant Water Relations And Photosynthetic Activity In Three Tunisian Chickpea (Cicer Arietinum L.) Genotypes Subjected To Drought, Abdelmajid Krouma
Turkish Journal of Agriculture and Forestry
Chickpea (Cicer arietinum L.) is an important food crop grown under rainfed conditions in Mediterranean regions in which drought is a major limiting factor for production. In these areas little attention is given to legumes, and efforts to identify drought-tolerant genotypes are primarily focused on major cereal crops. In the current study a greenhouse experiment was conducted to assess the effects of drought stress on plant growth, photosynthesis, and water relations in 3 Tunisian chickpea genotypes (Cicer arietinum L.). Drought was applied, and soil humidity was maintained at 30% of field capacity (stressed plants) or 100% of field capacity (control …

Turkish Journal of Agriculture and Forestry
The effect of pruning severity on quercetin and catechin content in berry skins of cv. Blaufränkisch (Vitis vinifera L.) was studied over 3 years. Different crop levels and canopy structures were obtained by retaining 8, 16, and 24 nodes per vine at pruning. Canopy density, which is proportionate to the shoot number per canopy volume, directly affects the intensity of photosynthetically active radiation (PAR). The quercetin content has been shown to be highly dependent on the light exposure of the berries in which it accumulates. An increase in node number linearly decreased skin catechin, and it is suggested that the …
Effects Of Cultural Practices On Weed Flora In Virginia (Flue-Cured) Organic Tobacco (Nicotiana Tabacum L.): Green Manure And Irrigation Systems, Anestis Karkanis, Dimitrios Bilalis, Aspasia Efthimiadou, Panagiotis Efthimiadis
Turkish Journal of Agriculture and Forestry
Organic tobacco is a new industrial crop. Field experiments were conducted, during 2005-2006, to determine the effects of irrigation system and green manure on weed flora in organic tobacco crops (Nicotiana tabacum cv. NC 71). The experiments were designed as a split plot design with 4 replicates, 2 main plots (drip and sprinkler irrigation), and 3 sub-plots (vetch and red clover as green manure, and control). The greatest number and dry weight of weeds was observed in sprinkler irrigation. Our results indicate that weed distribution under drip and sprinkler irrigation is related not only to the surface soil water content …

Pathogen Reduction Effects Of Solar Drying And Soil Application In Sewage Sludge, Nurtaç Öğleni̇, Sai̇m Özdemi̇r
Turkish Journal of Agriculture and Forestry
The responses of sludge faecal coliforms, Salmonella, and Ascaris lumbricoides to heat drying, solar dehydration, and inactivation in soil are examined in this study. The presence of Salmonella in raw sludge cake after treatment was low, and absent for most of the cases. Likewise, the viable Ascaris eggs were not determined because of absent or low prevalence. Faecal coliforms, on the other hand, drastically decreased from 4.2 × 10^7 MPN g^{-1} Dry Solid (DS) to absence by heat drying. Faecal coliform numbers in solar and non-solar drying treatments were not declined below 1.0 × 10^3 MPN g^{-1} after drying to …

Effect Of Foliar Applied Kinetin And Indole Acetic Acid On Maize Plants Grown Under Saline Conditions, Cengi̇z Kaya, Ati̇lla Levent Tuna, Abdulkadi̇r Mustafa Okant
Turkish Journal of Agriculture and Forestry
This study examined the effects of kinetin (KIN) and indoleacetic acid (IAA) sprayed on the leaves of salinity-stressed maize (Zea mays L. cv., DK 647 F1) plants grown in field conditions. Salt stress was created by adding 100 mM NaCl to the irrigation water through a drip irrigation system during the irrigation schedule. Kinetin (KIN), indole acetic acid (IAA), and their combinations were sprayed foliarly. Salt stress (S) reduced the total dry matter, grain yield, chlorophyll content, and relative water content (RWC), but increased electrolyte leakage and proline accumulation in the maize plants. Foliar applications of both KIN and IAA …

Turkish Journal of Agriculture and Forestry
Taking into account the importance of distribution and transfer of radionuclides in the soil-water-plant system, especially in agricultural fields, in this study, natural radionuclide determination in regosol-type soil was performed. The correlations between main soil properties and the contents of natural isotopes ^{238}U, ^{226}Ra, ^{232}Th, and ^{40}K in agricultural soil and their distribution through the soil depth was studied. For determination of natural radionuclide activity concentration, we used the CANBERRA HPGe detector, applying the gamma spectrometry method. The investigation was performed on an experimental peach tree field characterized by a anthrosol type of soil, derived from the chernozem type of …
