In a nematode survey of Tylenchida carried out in groundnut (Arachis hypogaea L.) growing areas in the Mediterranean region of Turkey, 15 species were determined as belonging to ten genera of eight families within the superfamilies Tylenchoidea, Dolichodoroidea, Hoplolaimoidea and Anguinoidea. Each of them constitutes a new record on groundnut in Turkey, andScutylenchus tumensis Skwiercz andPratylenchus brachyurus (Godfrey) are reported for the first time in the nematofauna of Turkey.  相似文献

This study aimed to investigate a cultivar selection criterion based on income ha−1 in common wheat. Regional yield trials with 20 entries were planted in Diyarbakır, Hazro and Ceylanpınar in southeast Anatolia in the 2004/2005 growing season. A randomized complete block design with four replications was employed. Grain samples from each location were subjected to quality analyses, and then presented to randomly selected grain purchasers with the local commodity market for market price estimations. Entries 1, 9, 10, 7 and 6 were the top five ranking entries for grain yield, giving 5,320, 5,290, 5,280, 5,140 and 5,130 kg ha−1, respectively. From the market price perspective, entries 17, 3, 7, 20 and 8 received the five highest marketing price offers with the values 239.0, 238.1, 237.1, 236.9 and 236.7 US$ tonne−1, respectively. There was a US$ 10.94 tonne−1 market price difference between entries with the highest and the lowest market price. The only quality analyses showing significant correlations with market price were Zeleny sedimentation value and hectolitre weights (kg hl−1). From thev production income [= marketing price (US$ tonne−1) × grain yield (kg ha−1)] point of view, entries 9, 10, 1, 7 and 6 were ranked from 1st to 5th for production income ha−1 with the values 1,241.0, 1,238.0, 1,219.9, 1,214.2 and 1,209.3 US$ ha−1, respectively. All five high yielding entries were also high-income entries. A rank stability analysis further indicated that entry numbers 6, 7, 8, 4 and 1 stable for high production income ha−1. A simulation study, based on allocation of additional premiums for high quality indicated that entries 9,1,10, 7, and 6 would be top ranking for high income ha−1 if given an additional premium of as much as twice the standard deviations of market price for each entry (the highest premium limit; 20.24 US$ tonne−1). The order for cultivar preference for high production income ha−1 would change and would generate 1,321.94, 1,296.20, 1,281.11, 1,258.06 and 1,243.01 US$ ha−1, respectively. It was concluded that the relatively quality conscious Şanlıurfa commodity market does not offer adequate premiums for the high quality grains. This results in farmer preference for high yielding lower quality cultivars. Even though quality cannot be neglected, and cultivar preference could change with additional premiums, breeders must give more attention to high production income ha−1.  相似文献

The Tatura system for the preparation of seed-beds for irrigated annual row-crops is described, where the soil is tilled when wet and friable and so requires few passes with implements to become suitable for crops, and where seeds are sown into wet soil. In soil prepared by the Tatura system, the percentage of aggregates < 0.5 mm diameter (as measured by dry-sieving) in the seed-bed was about half that found in commercially prepared seed-beds which were tilled up to 50 times when dry. With the Tatura system, the wetter the soil (up to 22% water content) when tilled, or the more passes (up to 4) of the implement at a water content of 22%, the less dust (< 0.5 mm diameter) and/or fewer clods (> 20 mm diameter) were formed.

The macro-structure of the surface layer of soil tilled at different water contents by the Tatura system was also quantified statistically by the method of wax-impregnation. The macro-structures were compared at the 10 mm, 20 mm, 40 mm, 60 mm and 80 mm depths in beds of soil prepared for irrigated annual row-crops by a system which has been described previously. Within each treatment (21.7%; 19.0%; 11.6% water content at 0–100 mm depth at tillage), the linear porosity and mean pore-size each tended to decrease with depth to 40 mm, with no further change or slight decrease to 80 mm depth. In all treatments, the mean aggregate-size tended to increase with depth from 10 mm depth to 80 mm depth. The sizes of pores and aggregates varied across each bed and possibly depended on the position of tines within the bed at each pass at tillage. Water content at tillage led to small differences in structure of the beds of soil. Soil tilled at a water content slightly above the Casagrande Plastic Limit generally had slightly larger pores and aggregates than soil tilled at lower water contents.  相似文献

This study investigates the effects of different temperatures on the total carbohydrate, lipid and protein amounts of Acanthoscelides obtectus Say, which is a common cereal pest. Studies have been carried out under laboratory conditions at 20 +/- 2 degrees C, 30 +/- 2 degrees C and 60 +/- 5% relative humidity. No specific photoperiodic regimen has been used throughout the study. Total carbohydrate, protein and lipid amounts for females at 20 degrees C were 61.74, 35.77 and 83.79 microg/individual, respectively, whereas the amounts for males were 34.94, 29.53 and 57.98 microg/individual, respectively. At 30 degrees C, total carbohydrate, protein and lipid amounts for females were 92.00, 42.18 and 83.26 microg/individual, respectively. The amounts at the same temperature for males were 43.34, 34.08 and 52.19 microg/individual, respectively. In both sexes, total carbohydrate and protein amounts at 30 degrees C were higher than those at 20 degrees C whereas this was not true for total lipid amounts.  相似文献

Variations in protein and carbohydrate levels correlated with the age and sex of Galleria mellonella (Linnaeus, 1758) (Lepidoptera: Pyralidae) in constant lightness and darkness were investigated. Tests were conducted under laboratory conditions at 28 +/- 2 degrees C temperature and 65 +/- 5% relative humidity. Insects were fed on combs without honey. Protein level in 100 mg of adults increased in the first days of adult life of females in connection with their age and then decreased. No difference was observed in males. Carbohydrate level in 100 mg of adults increased in both sexes in connection with their age. In all tests carbohydrate and protein levels of females were found higher than males. Protein and carbohydrate levels of adult G. mellonella varied in connection with the photoperiod regimes implemented. Decrease in the nutrient levels was observed in constant darkness.  相似文献

Deficiency of Boron (B) is widespread in the many parts of region of Turkey. So, the effects of boron and plant growth promoting bacteria (Bio-B) on the fruit yield, antioxidant enzyme activity and plant freeze injury of strawberry cv. Fern were investigated under field conditions between 2013 and 2014. The experimental plot was a completely randomized design with 4 replicates. Control and Bio-B were used as fertilizer agent in the experiment. Bio-B fertilizer was applied in three methods as soil, foliar and soil + foliar application methods to strawberry plants. Data through 2 years showed that the use of Bio-B significantly increased fruit yield, antioxidant enzyme activity and decreased freeze injury of strawberry leaf. Soil + foliar applications of Bio-B fertilizer increased to fruit yield compared to the control by 55.91?%. However, foliar application of Bio-B fertilizer increased to catalase (CAT), peroxidase (POD), and superoxide dismutase (SOD) enzyme activity compared with the control treatment 41.86?%, 48.99?%, and 26.59?%, respectively and decreased freeze injury of strawberry leaves 27.41?%. Overall, the results of this study suggest that Bio-B fertilizer application have the potential to increase the yield, antioxidant enzyme activity and decreased freeze injury of strawberry plants under field conditions.  相似文献

Tuberculosis (TB) is an important zoonosis affecting a wide range of hosts. An abattoir study was conducted on 1,536 randomly selected male goats slaughtered at Modjo Modern Export Abattoir to determine the prevalence of tuberculosis in slaughtered goats. Carcasses and organs of all the study animals were first examined by routine meat inspection followed by detailed meat inspection. Samples from tuberculous lesions were cultured for mycobacterial isolation and identification. Histopathology was done on 31 samples with tuberculous lesions. Detailed meat inspection detected 65 (4.2%; 95% confidence interval (CI) = 3.3–5.4%) tuberculous lesions. From these, 20 (30.8%) samples were confirmed mycobacterium positive on culture, out of which 18 were Mycobacterium bovis and two were Mycobacterium tuberculosis. Routine meat inspection failed to detect tuberculous lesions in 23% of carcasses with TB lesions detected by detailed examination. However, no statistically significant difference was observed between both methods in detecting tuberculous lesions (Kappa = 0.87). Origin and age of the goats did not statistically affect the disease prevalence (P > 0.05). Histopathologic lesions were observed in 21 samples (68%; 95% CI = 50.1–81.4%) out of the 31 carcasses with gross tuberculous lesions examined by histopathology. Eighteen (58%) tuberculous samples positive for histopathology were also culture positive. The sensitivity and specificity of histopathology were 90% (95% CI = 76.9–100%) and 72.7% (95% CI = 46.4–99%), respectively, using culture as a reference test. To the best of our knowledge, this is the first report of caprine tuberculosis from Ethiopia. Further studies are required at the farm level to determine the prevalence of tuberculosis in the general goat population.  相似文献
