Larvae of the cereal leaf minerSyringopais temperatella Led. (Lep.: Scythridae) collected from wheat and barley fields in the southeast Anatolian region of Turkey during 2005–2006,
and their parasitization rates, were determined in the laboratory,Bracon (Habrobracon) stabilis Wesmael andApanteles sp. (Hymenoptera: Braconidae) were identified as its parasitoids for the first time. 相似文献

This research was conducted to evaluate the effect of zinc, added into compound fertilizer in the production process, and zinc applied together with compound fertilizer on yield and quality component of sugar beet in 2009–2010.The treatments consisted of nitrogen, phosphorus and potassium (NPK) (12-30-12) compound fertilizer; 2. NPK (12-30-12) compound fertilizer + zinc sulfate and NPK (10-20-20) + 1% Zn compound fertilizer. Root yield, sugar percentage, white sugar percentage (WSP), white sugar yield (WSY), alpha-amino nitrogen, sodium and potassium concentration were investigated in this study. A total of 5 kg ha?1 zinc application on sugar beet significantly increased the yield and quality of sugar beet; the rate of increase was in the range of 4.62–6.97% in root yield, 2.09–5.75% in sugar percentage, 2.60–8.03% in WSP and 7.84–13.06% in WSY. NPK (10-20-20) + 1% Zn compound fertilizer and NPK (12-30-12) compound fertilizer + zinc applications increased the sugar beet yield and quality values in both years. 相似文献

Improved winter wheat (Triticum aestivum L.) cultivars are needed for the diverse environments in Central and West Asia to improve rural livelihoods. This study was
conducted to determine the performance of elite winter wheat breeding lines developed by the International Winter Wheat Improvement
Program (IWWIP), to analyze their stability across diverse environments, and to identify superior genotypes that could be
valuable for winter wheat improvement or varietal release. One hundred and one advanced winter wheat breeding lines and four
check cultivars were tested over a 5-year period (2004–2008). Grain yield and agronomic traits were analyzed. Stability and
genotypic superiority for grain yield were determined using genotype and genotype × environment (GGE) biplot analysis. The
experimental genotypes showed high levels of grain yield in each year, with mean values ranging from 3.9 to 6.7 t ha−1. A set of 25 experimental genotypes was identified. These were either equal or superior to the best check based on their
high mean yield and stability across environments as assessed by the GGE biplot analysis. The more stable high yielding genotypes
were ID800994.W/Falke, Agri/Nac//Attila, ID800994W/Vee//F900K/3/Pony/Opata, AU//YT542/N10B/3/II8260/4/JI/Hys/5/Yunnat Esskiy/6/KS82W409/Spn
and F130-L-1-12/MV12. The superior genotypes also had acceptable maturity, plant height and 1,000-kernel weight. Among the
superior lines, Agri/Nac//Attila and Shark/F4105W2.1 have already been proposed for release in Kyrgyzstan and Georgia, respectively.
The findings provide information on wide adaptation of the internationally important winter wheat genotypes, and demonstrate
that the IWWIP program is enriching the germplasm base in the region with superior winter wheat genotypes to the benefit of
national and international winter wheat improvement programs. 相似文献

This report describes nitrate poisoning observed in thoroughbred mares. Nine horses died at a farm in Bursa, Turkey, between February and April of 2008. Five of them were pregnant. Clinical findings developed over a short period and included severe abdominal pain, limited response to analgesics and antispasmodics, diarrhea, shallow and rapid breathing, tachycardia, blue-brown discoloration of the mucosal membranes, tremors, ataxia, convulsions before death, and abortion in the pregnant mares. The main postmortem finding was chocolate brown–colored blood as well as congestion and inflammation of the intra-abdominal organs. Uterine rupture, colonic ruptures, and torsio uteri were seen in the pregnant mares. Stomach and intestinal ruptures were seen in four nonpregnant mares. High nitrate concentrations were determined in some grass and alfalfa samples used to feed the animals. Nitrate poisoning is considered to be very rare in horses, but, in this case, the clinical symptoms, postmortem findings, and nitrate levels in the collected samples supported nitrate and nitrite poisoning as the cause of deaths. 相似文献

SummaryThe characterisation of sweet cherry (Prunus avium L.) genetic resources in Turkey may help to increase their use in breeding programmes worldwide, as Turkey is the centre of origin of sweet cherry. Amplified fragment length polymorphism (AFLP) and simple sequence repeat (SSR) markers were therefore used to analyse genetic diversity among a total of 78 local and introduced sweet cherry cultivars. Four AFLP primer combinations, and six SSR primer pairs for sweet cherry were used for genetic diversity analysis. A genetic similarity matrix was calculated using the combined data from AFLP and SSR analyses with simple matching coefficient. Genetic similarities among the sweet cherry genotypes studied were higher than 42%. No two accessions had an identical AFLP and SSR marker profile, indicating that all 78 genotypes were unique. An UPGMA dendrogram, based on the similarity matrix, revealed 18 separate Groups at or above the 70% similarity level. While some Groups consisted of both introduced and local genotypes, other Groups had only local genotypes. This result suggests that there was broad genetic diversity among the local Turkish sweet cherry genotypes, which was not present in the introduced sweet cherry accessions. The genetic variation present in local Turkish sweet cherry genotypes may be useful for future breeding programmes. We found that the use of both SSR and AFLP marker systems was effective for distinguishing between genetically-close sweet cherry genotypes. These marker systems can be used to complement pomological and morphological markers during the characterisation and identification of sweet cherry genotypes. 相似文献

Genotype X environment interactions were estimated for several traits in potato from a combined analysis of 11 genotypes grown at 3 locations for 2 years. Genotype X location X year and Genotype X location interactions were significant for the majority of the traits studied. Yield, reducing sugar content, dry matter content, leaf area, plant height and starch content should be tested over multiple locations and years in order to separate the genotype × environment interaction components from the total genotypic variance. 相似文献

In this study we aimed to reveal the ranges and effectiveness of soil parameters on the distribution of H. strobilaceum. Halocnemum strobilaceum Bieb. is a widespread species in saline habitats and the distribution pattern of this halophytic species around Lake Tuz in Central Anatolia was examined according to the soil characteristics. pH, electrical conductivity, soil humidity, salt percentage, soluble Ca2+, Mg2+, Na+, K+, CO3(2-), HCO3(-), Cl(-) and SO4(2-) values, total cations, cation exchange capacity, sodium adsorption ratio, exchangeable Na+, K+, Ca2+ and Mg2+ values were the examined soil properties. The most effective soil parameters for flowering period were found as Na, SO4, total cations, SAR and EC and for seed bearing period as EC, Mg, total cations, Cl, Na, SO4 and salt (%) content of the soil. 相似文献
