Effects of Different Effective Microorganism and Nitrogen Fertilization Doses On Seed Yield and Quality of Pepper (Capsicum annuum L.) Plants     

Demirkaya  Mustafa  Güneş  Adem 《Gesunde Pflanzen》2022,74(1):125-132

As in Turkey, pepper is among the most widely produced and consumed plant species worldwide. Plant nutrients and fertilization programs have significant effects on seed yield and quality of peppers. Therefore, this study was conducted to investigate the effects of effective microorganism (EM) treatments and nitrogen fertilization on seed yield and quality parameters of peppers. Kandil Dolma and Yalova Çorbac? pepper cultivars commonly grown in Turkey were used as the plant material of the experiments. Three different EM treatments (0, 2 and 3?L da^?1 EM) with and without N fertilizer were used. The greatest seed yield of both cultivars (68.57?kg da^?1 in Kandil Dolma and 94.90?kg da^?1 in Yalova Çorbac?) were obtained from 3?L EM?+?2.60?kg da ^?1 N treatments. EM treatments increased germination ratio of Yalova Çorbac?, but the differences in mean germination times were not found to be significant. Germination index, an indicator of seed performance, increased with EM treatments in both cultivars.

Tuning the quantum stability and superconductivity of ultrathin metal alloys     

Ozer MM  Jia Y  Zhang Z  Thompson JR  Weitering HH 《Science (New York, N.Y.)》2007,316(5831):1594-1597

Quantum confinement of itinerant electrons in atomically smooth ultrathin lead films produces strong oscillations in the thickness-dependent film energy. By adding extra electrons via bismuth alloying, we showed that both the structural stability and the superconducting properties of such films can be tuned. The phase boundary (upper critical field) between the superconducting vortex state and the normal state indicates an anomalous suppression of superconducting order just below the critical temperature, Tc. This suppression varies systematically with the film thickness and the bismuth content and can be parametrized in terms of a characteristic temperature, Tc* (less than Tc), that is inversely proportional to the scattering mean free path. The results indicate that the isotropic nature of the superconductive pairing in bulk lead-bismuth alloys is altered in the quantum regime.  相似文献   

Human CHN1 mutations hyperactivate alpha2-chimaerin and cause Duane's retraction syndrome

Duane's retraction syndrome (DRS) is a complex congenital eye movement disorder caused by aberrant innervation of the extraocular muscles by axons of brainstem motor neurons. Studying families with a variant form of the disorder (DURS2-DRS), we have identified causative heterozygous missense mutations in CHN1, a gene on chromosome 2q31 that encodes alpha2-chimaerin, a Rac guanosine triphosphatase-activating protein (RacGAP) signaling protein previously implicated in the pathfinding of corticospinal axons in mice. We found that these are gain-of-function mutations that increase alpha2-chimaerin RacGAP activity in vitro. Several of the mutations appeared to enhance alpha2-chimaerin translocation to the cell membrane or enhance its ability to self-associate. Expression of mutant alpha2-chimaerin constructs in chick embryos resulted in failure of oculomotor axons to innervate their target extraocular muscles. We conclude that alpha2-chimaerin has a critical developmental function in ocular motor axon pathfinding.  相似文献   

Stone, disc and hammer milling of bulgur   总被引：1，自引：0，他引：1  

Mustafa Bayram  Mehmet Durdu ner 《Journal of Cereal Science》2005,41(3):291-296

The effects on the milling quality of bulgur were compared using stone, disc and hammer mills. For each milling system bulgur particles were examined for appearance, surface structure, dimensions (max., min., mean, standard deviations and coefficient of variance), particle size distribution, bulk density and 1000 particle weight. Smooth and regular shaped bulgur particles were obtained using the abrasive stone and disc mills. Stone milled bulgur particles, were not split or glassy, but were opaque. Hammer milling significantly affected the appearance and surface characteristics of the bulgur particles and gave the lowest minimum dimensions and the highest deviation and variance in dimensions. The milling yields for hammer (98.3%) and stone (97.4%) mills were higher than for the disc mill (96.5%). Each mill gave a different distribution between coarse, medium and fine fractions. The highest yield of the coarse fraction (83.1%) was obtained using the stone mill. The results indicate that due to loss of quality, hammer milling is not suitable for bulgur preparation.  相似文献   

Studies on samh seeds (Mesembryanthemum forsskalei Hochst) growing in Saudi Arabia: 3. Utilization of samh seeds in bakery products     

Abdelmoneim I. Mustafa  M. Saleh Al-Jassir  M. A. Nawawy  S. E. Ahmed 《Plant foods for human nutrition (Dordrecht, Netherlands)》1995,48(4):279-286

Samh seeds obtained from Al-Jouf area were ground into flour analyzed and used as a replacement for wheat in the ratio of 10, 20 and 30% for bread and 30, 60 100% for cookies. The rheological effect of the Samh flour on Saudi wheat flour was also studied. The bread and cookies obtained were evaluated physically and by sensory evaluation. The results obtained indicated that samh flour has high protein content and could be used as a replacement for wheat flour upto 30% without adversely affecting the bread specific volume much. Samh flour has improved the cookies appearance specially the colour (chocolate colour) and spreading ratio. The results also revealed that it is possible to make cookies from 100% samh flour. Due to the high protein content of the samh seeds the nutritional value of the bread and cookies made with samh flour will be improved. The results of the sensory evaluation of the bread and cookies indicated that the bread made with samh flour upto 30% has similar characters except for the crumb color and the overall acceptability which were rated as significantly inferior. The sensory evaluation of the cookies showed that the cookies made with samh flour upto 100% were significantly superior (p<0.05) to the cookies made with 100% wheat flour (control).  相似文献   

Investigation of seroprevalence of <Emphasis Type="Italic">Theileria equi</Emphasis> and <Emphasis Type="Italic">Babesia caballi</Emphasis> in horses in Nigde province,Turkey     

Bilge Karatepe  Mustafa Karatepe  Ayşe Çakmak  Zafer Karaer  Gül Ergün 《Tropical animal health and production》2009,41(1):109-113

The prevalence of equine piroplasmosis caused by Theileria equi and Babesia caballi in Nigde, in central Anatolia, Turkey has remained unknown. Serum samples were obtained from a total of 125 horses and were tested for antibodies to T. equi and B. caballi using the Indirect Fluorescence Antibody Test (IFAT). Twenty-three (18.4%) horses were seropositive for equine piroplasmosis. Anti-T. equi was observed in 16 horses (12.8%) while anti-B. caballi was detected in 12 horses (9.6%). In addition, 5 serum samples were positive for both parasites. The prevalence rates of antibodies to T. equi and B. caballi for female and male horses were statistically indifferent (p = 0.19 and 0.90). The difference between the seropositivity rates to T. equi among age groups was statistically insignificant (p = 0.44) while the difference to B. caballi among age groups is statistically significant (p = 0.01). Seropositivity rates ranged from 2.9% to 25.7% for T. equi and 2.9% to 14.3% for B. caballi from the selected districts in Nigde. A statistically significant difference on seropositivity rates for the study sites was observed for only T.equi (p = 0.03). This study indicates that T. equi is higher than B. caballi in Nigde. This study was supported by the Scientific Research Projects Unit of Nigde University (FEB 2007/08).  相似文献   

The occurrence and antibiotic resistance of motile Aeromonas in livestock     

Ceylan E  Berktas M  Ağaoğlu Z 《Tropical animal health and production》2009,41(2):199-204

The present study was carried out to assess the prevalence of motile Aeromonas spp. in the faeces of clinically healthy sheep, cattle and horses and evaluate their susceptibility to some anti-microbial agents. Rectal swabs from 120 sheep, 85 cattle and 20 horses were examined for Aeromonas species using alkaline peptone water (pH 8.4) as the enrichment medium and Aeromonas Selective Agar containing 5 mg/l ampicillin as the isolation medium. Identification and antibiotic resistance of motile Aeromonas strains was performed using Gram Negative Enteric ID panel. Motile aeromonads were isolated from 12 (10%) sheep, 7 (8.2%) cattle and 1 (5%) horse. Of these 20 aeromonad isolates, 13 were A. caviae, 6 were A.sobria and 1 was A. hydrophila. Aeromonas species in the faeces of livestock might pose a public health problem for humans who are in direct contact with contaminated animals. However, further studies should be performed on aeromonads relating to their transmission between animals and humans.  相似文献   

Effects of hypotaurine, cysteamine and aminoacids solution on post-thaw microscopic and oxidative stress parameters of Angora goat semen     

Mustafa Numan Bucak  Pürhan Barbaros Tuncer  Serpil Sar&#x;zkan  P&#x;nar Alk&#x;m Uluta  Kenan oyan  Nuri Bap&#x;nar  Birol zkalp 《Research in veterinary science》2009,87(3):468-472

This study was conducted to determine the effects of cysteamine, hypotaurine and aminoacids solution (BME) on standard semen parameters, lipid peroxidation and antioxidant activities of Angora goat semen after the freeze–thawing process. Ejaculates collected from four Angora goats were evaluated and pooled at 37 °C. Semen samples, which were diluted with a Tris-based extender containing the antioxidants hypotaurine (5 mM) and cysteamine (5 mM), and an aminoacid solution (13%), and an extender containing no antioxidants (control), were cooled to 5 °C and frozen in 0.25-ml French straws in liquid nitrogen. Frozen straws were thawed individually at 37 °C for 20 s in a water bath for evaluation.Supplementation with cysteamine, hypotaurine and BME caused significant (P < 0.05) increases in sperm motility, and significant (P < 0.05) decreases in total abnormality rates in comparison to the control group. While all in vitro treatments did not affect the acrosomal abnormality rates, hypotaurine and BME but not cysteamine significantly (P < 0.05) increased the HOST results as compared to the control group. Supplementation with antioxidants and BME did not significantly affect MDA levels and CAT activity in comparison to the control group (P > 0.05). The antioxidants hypotaurine and cysteamine decreased SOD activity when compared to the BME group and controls (P < 0.001).  相似文献   

Effect of varying ruminally degradable to ruminally undegradable protein ratio on nutrient intake, digestibility and N metabolism in Nili Ravi buffalo calves (Bubalus bubalis)     

J.I. Sultan  A. Javaid  M. Nadeem  M.Z. Akhtar  M.I. Mustafa 《Livestock Science》2009,122(2-3):130-133

Four Nili-Ravi buffalo calves (100 ± 4 kg) were used in 4 × 4 Latin Square Design to evaluate the influence of varying ruminally degradable protein (RDP) to ruminally undegradable protein (RUP) ratio on dry matter intake (DMI), digestibility and nitrogen (N) metabolism. Four experimental diets A, B, C and D were formulated to contain RDP:RUP of 70:30, 65:35, 60:40 and 55:45, respectively. The calves were fed ad libitum. Dry matter intake by calves fed C diet was higher (P < 0.05) than those fed D diet and lower (P < 0.05) than calves fed A diet, however, it was similar to those fed B diet. There was a linear decrease (P < 0.01) in DMI with decreasing the RDP to RUP ratio. Similar trend was noticed in crude protein (CP) intake. Neutral detergent fiber (NDF) intake was significantly different across all treatment. The decrease in CP and NDF intake was due to decreasing trend of DMI. Dry matter (DM) digestibility in calves fed A and B diets was higher (P < 0.05) than those fed C and D diets. A linear decrease (P < 0.01) in DM digestibility was observed with decreasing the RDP to RUP ratio. Crude protein digestibility remained unaltered across all treatments. Neutral detergent fiber digestibility was higher in calves fed A and B diets than those fed C and D diets. Higher NDF digestibility in calves fed A and B diets was due to higher level of dietary RDP that might resulted in higher ruminal ammonia concentration which stimulate activity of cellulytic bacteria and ultimately increased NDF digestibility. The N retention (g/d) was similar among the calves fed B, C and D diets, however, it was higher (P < 0.05) than those fed A diet. Decreasing the RDP to RUP ratio resulted in linear increase (P < 0.01) in N retention. The N retention, as percent of N intake was significantly different across all treatments. Decreasing RDP to RUP ratio resulted in linear increase (P < 0.01) in N retention, as percent of N intake. A similar trend was noticed in N retention, as percentage of N digestion. Blood urea nitrogen (BUN) concentration in calves fed B diet was higher (P < 0.05) than those fed D diet and was lower (P < 0.05) than those fed A diet, however, it was not different from calves fed C diet. Decreasing dietary RDP to RUP ratio resulted in linear decrease (P < 0.05) in BUN concentrations. The decrease in BUN concentration was because of decreasing level of dietary RDP. The N retention can be increased by decreasing RDP to RUP ratio in the diet of growing buffalo calves and diet containing RDP to RUP ratio 55:45 is considered optimum regarding N retention in buffalo calves.  相似文献   

Determination of the muscle residue levels and withdrawal time of florfenicol in healthy and experimentally Lactococcus garvieae infected rainbow trout (Oncorhynchus mykiss,Walbaum 1792) grown in the Black Sea water     

Mustafa Türe  Erkan Taba  Emine Baydan  &#x;lyas Kutlu  Cemil Altunta  Farah Gnül Ayd&#x;n  Emre Arslanba  Gzde Yücel Tenekeci 《Aquaculture Research》2019,50(7):1964-1972

The aim of this study was to determine, muscle residue level (MRL) and withdrawal time (WT) of florfenicol (FF), in healthy and infected rainbow trout (Oncorhynchus mykiss) with Lactococcus garvieae. Fish were divided into the four groups, Group I (Infected fish fed with FF free diet, n = 10), Group II (Healthy fish fed with FF free diet, n = 10), Group III (Infected fish fed with FF containing diet, n = 80) and Group IV (Healthy fish fed with FF containing diet, n = 80). Fish in Group I and Group III were infected with 1.8×10⁶ cfu/ml Lactococcus garvieae by immersion. FF containing diet was applied fish (10 mg kg^‐1 day^‐1) in Group III and IV for 10 days. FF residues in fish muscles were analysed by validated HPLC method. The limit of detection (LOD) and limit of quantification (LOQ) values of the method were determined to be 0.31 μg/g and 0.64 μg/g, respectively, and the recovery was 92.61%. As a result of the experiments, there was no significant difference between the infected and healthy group in term of MRLs. However, in both groups, it was determined that third‐day values were below MRLs (1,000 μg/kg). Also, the WT values were lower than the 500°C‐day values reported in the EC commission decision in both groups and were determined as 14.5 and 14.12 (water temperature mean 18°C ± 1) per day, respectively.  相似文献
