This study presents and discusses the results of a fire behavior study conducted in Anatolian black pine (Pinus nigra J.F. Arnold subsp. nigra var. caramanica (Loudon) Rehder) slash. A total of 30 experimental fires were conducted over 3 years under varying weather and fuel loading conditions in aging slash. Relationships between fire behavior and fuel properties and weather conditions were determined with correlation and regression analyses. Spread rate, fuel consumption, and fire intensity were all related to fuel properties and weather, and ranged from 0.2 to 3.1 m min^{-1}, from 0.71 to 6.65 kg m^{-2}, and from 14.05 to 3961.46 …
Effect Of Upper Plant Parts On Yield And Quality In Turkish Durum Wheat Landraces From Different Regions, Altitudes, And Provinces, Nusret Zenci̇rci̇
Effect Of Upper Plant Parts On Yield And Quality In Turkish Durum Wheat Landraces From Different Regions, Altitudes, And Provinces, Nusret Zenci̇rci̇

The aim was to explore 117 durum wheat (T. turgidum L. conv. durum (Desf.) MacKey) landraces from 2 regions, 5 altitude intervals, and 12 provinces for flag leaf length, width, angle, sheath length, fertile spikes, spike length and width, plant yield, percent vitreous kernel, pearling index, percent grain protein, and 1000 kernel weight. The field experiment consisted of 566 single plant selections from 117 populations with Kunduru 1149 and Kızıltan 91 controls, analyzed via descriptive and multivariate statistical methods. Plant yield with the highest variation was positively correlated with flag leaf length, flag leaf sheath length, and spike width. While …

Regression equations were developed to estimate shrub fuel biomass of a maquis formation in western Turkey. The relationships between some shrub characteristics and live, dead, available (for consumption), and total fuel biomass were determined by simple/multiple linear regression. Measured biomass values for live, available, and total fuels varied from 0.70 to 6.74 kg m^{-2}, from 0.78 to 3.03 kg m^{-2}, and from 1.06 to 7.72 kg m^{-2}, respectively. The results obtained indicated that shrub fuel biomass could be satisfactorily predicted using the regression equations generated. The resulting equations were able to account for 60% to 89% of the observed variation …

Field surveys were carried out in 5 different citrus cultivation regions of Turkey in 2005 and 2006, and 201 samples were collected from different citrus species. Samples were tested for the presence of Citrus tristeza virus (CTV) by double antibody sandwich-enzyme-linked immunosorbent assay (DAS-ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). While DAS-ELISA showed that 41 trees were infected with CTV, an additional 13 trees were found to be positive based on RT-PCR. When CTV-positive samples were tested with the Western blot method using the monoclonal antibody MCA13, which is specific to severe isolates of CTV, 32 isolates, mostly from satsuma, …
Field Resistance Of Wheat (Triticum Aestivum L.) Genotypes From Different Countries To Leaf Rust (Puccinia Triticina), Beyhan Akin, Nusret Zenci̇rci̇, İzzet Özseven
Field Resistance Of Wheat (Triticum Aestivum L.) Genotypes From Different Countries To Leaf Rust (Puccinia Triticina), Beyhan Akin, Nusret Zenci̇rci̇, İzzet Özseven

Puccinia triticina causes leaf rust in wheat and results in severe yield losses in mild wheat growing areas of Turkey: Thrace, Marmara, Mediterranean, and Çukurova. A feasible way to avoid any damage is to grow slow rusting cultivars. We evaluated 94 wheat genotypes from different countries and 39 leaf rust differentials for their reactions to leaf rust field epidemics. Slow rusting, though, requires both the prediction of Lr genes in the greenhouse and an effective screening of genotypes against the leaf rust field epidemics; the evaluation at the sites regularly favoring leaf rust epidemics like Adapazarı is also possible.
