The use of organic materials as a source of nutrients on agricultural lands ameliorates soil physical properties as well as being an environmentally friendly way of disposing of their wastes. This study was conducted to determine effects of three organic materials (poultry litter, cattle manure, leonardite) on yield and nutrient uptake of silage maize. Poultry litter and cattle manure were applied based on phosphorus (P) or nitrogen (N) requirements of the crop whereas leonardite was applied only one dose (500 kg ha^?1) and also combined with three inorganic fertilizer doses (100%, 75%, 50% of recommended inorganic fertilizer dose). According to the results, the highest green herbage yield and nutrient uptake values were observed in LEO-100 whereas N-based treatments significantly decreased yield and nutrient uptake of silage maize. The use of organic materials as a combination with inorganic fertilizer in silage maize cultivation is highly beneficial for sustainable forage production.  相似文献   

Evaluation of Different Approaches for Respiratory Quotient Calculation and Effects of Nitrogen Sources on Respiratory Quotient Values of Hydrocarbon Bioremediation     

Kahraman  Bekir Fatih  Altın  Ahmet 《Water, air, and soil pollution》2020,231(7):1-12

Blechnum orientale L. is a traditional, medicinal fern found in China. To assess the characteristics of heavy metals and As accumulation, the fronds, roots, and the rooting soils of this fern were sampled from urban, suburban, and rural woodlands across Guangdong Province in southern China. The concentrations of As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, and Zn in both the fern and its rooting soils were separately detected by ICP-MS. Contamination levels of woodland rooting soils were also assessed using both a single pollution index and the Nemerow pollution index. Both the metal concentrations and the pollution index showed that soils from urban, suburban, and even rural woodlands were adversely contaminated by As, Cd, Hg, and Pb. Based on transfer factor, B. orientale had good translocation of As, Hg, and Mn, but poor translocation of Cd, Cr, Ni, Cu, Ni, Pb, and Zn from the roots to the fronds. This result suggests that this fern could be an excluder to latter metals. Despite the significantly higher levels of metals in the roots as compared with the fronds, the low bioaccumulation factor suggests that this fern has a weak capacity for metal accumulation.

Meat quality characteristics of Turkish indigenous Hair goat kids reared under traditional extensive production system: effects of slaughter age and gender     

Hayriye Deger Oral Toplu  Ergun Omer Goksoy  Ahmet Nazligul  Tolga Kahraman 《Tropical animal health and production》2013,45(6):1297-1304

Meat quality characteristics of Turkish indigenous Hair goat kids reared under an extensive production system were investigated in this study. A total of 60 Hair goat kids (30 females and 30 males) were slaughtered at 3, 6, 9, and 12 months of ages. Slaughter age significantly affected meat quality characteristics. Cooking loss (P?<?0.01) and shear force value (P?<?0.001) increased with age. Meat color became darker red with increasing slaughter age (P?<?0.001). The percentage of fat of musculus (M.) semimembranosus increased with age (P?<?0.01). The percentage of saturated fatty acids was significantly higher (P?<?0.01), whereas the percentage of unsaturated fatty acids was lower (P?<?0.001) in the M. longissimus dorsi of the kids slaughtered at 3 months of age than those in the other age groups. The females had higher intramuscular fat than that in males (P?<?0.001) and meat from male kids contained a higher percentage of polyunsaturated fatty acid than that from females (P?<?0.01). In conclusion, meat from Hair kids slaughtered between 3 and 9 months of ages had better quality than those slaughtered at the other ages and also meat from male kids had better quality than those female kids slaughtered at the same age under extensive production system.  相似文献

Genetic characterization of Allium tuncelianum: An endemic edible Allium species with garlic odor     

Meryem Ipek  Ahmet Ipek  Philipp W. Simon 《Scientia Horticulturae》2008

Allium tuncelianum (Kollman) Özhatay, Matthew & ?iraneci is a native species to the Eastern Anatolia. Its plant architecture resembles garlic (Allium sativum L.) and it has mild garlic odor and flavor. Because of these similarities between two species, A. tuncelianum has been locally called “garlic”. In addition, both A. tuncelianum and garlic has 16 chromosomes in their diploid genomes. Recently, A. tuncelianum has been suggested as the wild progenitor species of garlic. In this study, amplified fragment length polymorphisms (AFLP) markers and nucleotide sequence analysis of the internal transcribed spacer region (ITS) were used to assess genetic and phylogenetic relationships among A. tuncelianum, garlic and some other Allium species. AFLP analysis demonstrated that A. tuncelianum and garlic are genetically distinct and they are likely different species. Phylogenetic analyses based on the nucleotide sequence of ITS suggested that A. tuncelianum and garlic are distinct species and placed A. tuncelianum, garlic, Allium ampeloprasum and Allium scorodoprasum into the same clade in the neighbor joining dendrogram and in the consensus tree of parsimony analysis. However, A. tuncelianum was phylogenetically less related to garlic than either A. ampeloprasum or A. scorodoprasum, suggesting that A. tuncelianum may not be the immediate wild ancestor species of garlic. Further studies to generate hybrid progeny between A. tuncelianum and garlic (if possible) could provide more information on the homology between the chromosomes of A. tuncelianum and garlic and genetic relationships between these two species.  相似文献   

Fertility of lactating dairy cows inseminated with sex‐sorted or conventional semen after Ovsynch,Presynch–Ovsynch and Double‐Ovsynch protocols     

Ebru Karakaya‐Bilen  Gulnaz Yilmazbas‐Mecitoglu  Abdulkadir Keskin  Bar&#x;s Guner  Enes Serim  Jos E. P. Santos  Ahmet Gümen 《Reproduction in domestic animals》2019,54(2):309-316

The objective was to compare pregnancy per artificial insemination (P/AI) with conventional (CS) or sex‐sorted semen (SS) in dairy cows subjected to one of the three timed AI protocols. Cows (n = 356) were randomly assigned to synchronization with Ovsynch (OVS), Presynch–Ovsynch (PO) or Double‐Ovsynch (DO) and inseminated on Day 77 ± 3 postpartum with either frozen‐thawed SS (n = 182) or CS (n = 184) of the same bull. More cows were cyclic at the beginning of breeding Ovsynch increased (p < 0.01) with presynchronization and it was greater for DO than PO (OVS = 78.5%, PO = 85.1%, DO = 95.6%). Overall, P/AI for SS and CS increased with presynchronization (p < 0.05) on Days 31 (OVS = 35.5%, PO = 47.1%, DO = 48.3%) and 62 (OVS = 30.1%, PO = 43.8%, DO = 43.9%). Regardless of synchronization treatments, insemination with SS reduced P/AI (p < 0.02) on Days 31 (38.1% vs. 50.6%) and 62 (34.5% vs. 45.6%) compared with CS. No interaction was observed between synchronization treatment and type of semen for P/AI, although in cows receiving CS, P/AI was numerically greatest for PO (OVS = 42.0%, PO = 59.3%, DO = 49.0%), and in cows receiving SS, it was numerically greatest for those inseminated following DO (OVS = 27.9%, PO = 35.5%, DO = 47.6%). Thus, presynchronization improved P/AI in cows inseminated with sex‐sorted or conventional semen.  相似文献   

Myosin V walks hand-over-hand: single fluorophore imaging with 1.5-nm localization     

Yildiz A  Forkey JN  McKinney SA  Ha T  Goldman YE  Selvin PR 《Science (New York, N.Y.)》2003,300(5628):2061-2065

Myosin V is a dimeric molecular motor that moves processively on actin, with the center of mass moving approximately 37 nanometers for each adenosine triphosphate hydrolyzed. We have labeled myosin V with a single fluorophore at different positions in the light-chain domain and measured the step size with a standard deviation of <1.5 nanometers, with 0.5-second temporal resolution, and observation times of minutes. The step size alternates between 37 + 2x nm and 37 - 2x, where x is the distance along the direction of motion between the dye and the midpoint between the two heads. These results strongly support a hand-over-hand model of motility, not an inchworm model.  相似文献   

RESPONSE OF SALT STRESSED STRAWBERRY PLANTS TO FOLIAR SALICYLIC ACID PRE-TREATMENTS     

Omer Tohma  Ahmet Esitken 《Journal of plant nutrition》2013,36(4):590-599

Salinity has deleterious effects on plant growth and development through membrane stability, photosynthetic activity, protein content, and ionic composition; however, salicylic acid (SA) could restore these properties in plants. The objective of this study was to determine the ameliorative effects of SA as foliar pre-treatments on membrane permeability, proline and protein contents, chlorophyll a, b and total chlorophyll and ionic composition of strawberry cv. ‘Camarosa’ under saline conditions. Membrane permeability and proline content significantly increased and protein and chlorophyll contents significantly decreased by 6 mS cm^?1 application without SA treatment compared with the control (2 mS cm^?1) treatment. Membrane permeability decreased from 6.9 in 0 mM SA treatment to 5.2 by application of 1.0 mM SA under saline conditions and same to the control (5.2). Compared with 0 mM SA treatment, the average increases of proline and protein contents were 66.7% in 0.25 mM SA treatment and 62.2% in 0.1 mM SA treatment in 6 mS cm^?1 level, respectively. Chlorophyll b and total chlorophyll significantly increased by 0.25 mM SA treatments under saline conditions. The lowest and the highest chlorophyll b and total chlorophyll were obtained from 0 mM SA treatment (19.6 and 44.5 mg L^?1) and 0.25 mM SA treatment (28.6 and 52.9 mg L^?1) in 6 mS cm^?1 salinity level. Ionic compositions of leaves were significantly affected by salinity and SA treatments. Nitrogen in 1.0 mM SA treatment and P contents of leaves in 0.1 mM SA treatment significantly increased but Na and Cl contents of leaves significantly decreased by SA treatments in 6 mS cm^?1 salinity level. The results of this study were clearly indicated that the SA application on strawberry plants could ameliorate the deleterious effect of salt stress on membrane permeability, proline, protein, and chlorophyll contents. Therefore, SA treatment could offer an economic and simple application to salinity stress.  相似文献
