Determination of Graft Compatibility of Pear Cultivars Grafted on Different Rootstocks by Carbohydrate Analyses     

Çoban  Nermin  Öztürk  Ahmet 《Erwerbs-Obstbau》2022,64(2):229-235

In modern pear cultivation, clonal quince and pear rootstocks are preferred because they are easy to maintain and harvest. Also, they form dwarf plants and improve fruit quality compared to pear seedling rootstocks. However, graft incompatibility can be involved between different species or genera. The aim of the study was to determine the graft compatibility of the ‘Deveci’ and ‘Williams’ pear cultivars with different pear and quince rootstocks by carbohydrate analysis. Carbohydrate accumulation in the graft union was also observed with iodized potassium iodide (KI) staining. In terms of rootstocks, there were no differences in starch and carbohydrate content, but statistically differences were found in sugar contents. Significant differences were also found between cultivars and graft union in terms of the examined traits. Sugar content was highest in OHxF 333 and lowest in seedling rootstocks. There were no statistical differences in the starch content between the graft unions of the ‘Deveci’ cultivar, while starch accumulation was higher above the graft union than below and graft union in the ‘Williams’ cultivar grafted on the quince rootstock. In the study, it was determined that there were higher carbohydrate accumulation in the scion and graft union than below the graft union in ‘Williams’ grafted quince rootstocks, which was also confirmed by staining with KI. As a result of the study, it was concluded that carbohydrate accumulation analysis can be used to determine the graft compatibility of the pear cultivars with the different quince and pear rootstocks.

Effect of Organic Materials on Yields and Nutrient Accumulation of Wheat     

Refik Uyanöz  Ümmühan Çetin  Emel Karaarslan 《Journal of plant nutrition》2013,36(5):959-974

ABSTRACT

This experiment was conducted under greenhouse conditions using a sandy clay loam treated with garbage and mushroom composts, cattle and chicken manures, or municipal sludge at rates of 0, 30, or 60 ton ha^?1. The organic materials were applied to the pots and incubated for 15 d. The soil samples were watered at field capacity. In this experiment, wheat (Triticum aestivum L.) was used as a test crop. At the end of the experiment, it was found that treating sandy clay loam with the organic materials increased plant total and grain yields, protein content, 1000-kernel weight, number of grains in spike, and accumulation of nitrogen (N), phosphorus (P), potassium (K), iron (Fe), zinc (Zn), and manganese (Mn) by wheat compared with the control treatment, depending on the organic material applications. Thus, the increases were found to be statistically significant (P ≤ 0.05). Among the types of organic materials, the sewage sludge was the most effective material in increasing N, P, K, Fe, Zn, and Mn content of leaf, grain, and stem samples of the wheat plant. It was followed by mushroom compost and cattle manure. Based on the results, sewage sludge and garbage compost are suggested for use as an amendment for the soil studied. Comparing the beneficial effects of the organic materials applied for improving plant growth and nutrient accumulation, the materials can be arranged in the following descending order: municipal sludge > chicken manure > cattle manure > garbage compost > mushroom compost. It is suggested that recycling of organic materials for agricultural usage as an organic-matter resource is an alternative, organic fertilization option in Turkey.  相似文献

Selective determination of catechin among phenolic antioxidants with the use of a novel optical fiber reflectance sensor based on indophenol dye formation on nano-sized TiO₂     

Apak R  Demirci Çekiç S  Cetinkaya A  Filik H  Hayvalı M  Kılıç E 《Journal of agricultural and food chemistry》2012,60(11):2769-2777

The optical sensor for "tea catechins" was built by immobilizing 2,2'-(1,4-phenylenedivinylene)bis-8-hydroxyquinoline (PBHQ) on TiO? nanoparticles (NPs). The sensor worked by "indophenol blue" dye formation on PBHQ-immobilized TiO? NPs as a result of p-aminophenol (PAP) autoxidation with dissolved O? at pH 10. Among quercetin, rutin, naringenin, naringin, gallic acid, caffeic acid, ferulic acid, p-coumaric acid, catechin, epicatechin, epicatechin gallate, epigallocatechin, epigallocatechin gallate, and trolox, only catechin group antioxidants delayed the color formation on NPs, as measured by the reflectance signal at 710 nm. For quantitative analysis, reflectance signal versus time was recorded, and the difference between the areas under curve (ΔAUC) in the presence and absence of catechin was correlated (r = 0.98) to catechin concentration. The selectivity of the sensor for catechins was shown in tea infusions compared to other plant extracts and was ascribed to the nonplanar structure of catechin interfering with the formation of perfectly conjugated indophenol blue on TiO? surface.  相似文献   

Effect of dietary n-3 series fatty acids on sperm production in the freshwater crayfish, Astacus leptodactylus (Eschscholtz) (Astacidae)     

Muzaffer Mustafa Harlioğlu  Kenan Köprücü  Ayşe Gül Harlioğlu  Serpil Mişe Yonar  Tuba Çakmak Duran  Mehmet Nuri Çakmak  Önder Aksu  Sinan Özcan  Filiz Kutluyer  Hande Gündoğdu 《Aquaculture International》2013,21(2):273-282

The objective of the present work was to evaluate the effects of three different rates of long chain n-3 polyunsaturated fatty acid (LC n-3 PUFA) on the sperm number of Astacus leptodactylus. The experiment was carried out with the four following treatments: control group (not supplemented LC n-3 PUFA), D1 (1 %), D2 (2 %) and D3 (3 %). The sperm number of A. leptodactylus was counted; the reproductive system was weighted; and the macroscopical analysis of the testes and vasa deferentia (DVD) were conducted. In addition, gonado-somatic index (GI) and testes index (TI) were also calculated. The results showed that there was a significant difference between the crayfish fed LC n-3 PUFA supplemented diets (D1, D2, D3) and control in mean sperm number (P < 0.05). The highest sperm number was found for the crayfish fed D3 (6.27 ± 0.14 × 10⁸ sperm/distal vas deferens section). The results also showed that the reproductive system of the crayfish fed D3 and D2 was significantly heavier than that of the crayfish fed the control and D1 (P < 0.05). On the other hand, there was not a significant difference in the testes weight and vasa deferentia weight between the crayfish fed the control and D1, and between the crayfish fed D2 and D3 (P < 0.05). GI of the crayfish fed D3 and D2 was significantly higher than that of the crayfish fed control and D1 (P > 0.05), but there was not a significant difference in the TI of the crayfish fed control, D1, D2 and D3 (P > 0.05). In conclusion, diets containing different levels of LC n-3 PUFA significantly increase the sperm number of A. leptodactylus, and they are crucial for the production of higher number of sperm in this species.  相似文献   

The Effect of Liquid Smoking of Anchovy (Engraulis encrasicolus,L. 1758) Fillets on Sensory,Meat Yield,Polycyclic Aromatic Hydrocarbon (PAH) Content,and Chemical Changes     

Zayde Alçiçek  Özge Zencir  Gül Çelik Çakiroğullari  Hasan Hüseyin Atar 《Journal Of Aquatic Food Product Technology》2013,22(3-4):264-273

In this study, the effects of a commercial liquid smoke flavoring agent and two different brining solutions applied on fillets of anchovy were investigated by performing sensory analyses, meat yield, polycyclic aromatic hydrocarbon (PAH) content, and chemical composition analyses. Fillets were brined at 40 and 65% for 4 h at 4°C. Meat yield, sensorial acceptability, and chemical compositions were affected by each brining level. No detectable PAH levels were found in smoke flavoring treated fish samples. Sixty-five percent salt level was rejected by the participants due to high salt content. The results of the study showed that liquid smoke flavoring treatment is applicable to the anchovy fillets, and 40% brining level is recommended.  相似文献

Meryem Yeşim Çelik  Sedat Karayücel  İsmihan Karayücel  Recep Öztürk  Bora Eyüboğlu 《Journal Of Aquatic Food Product Technology》2013,22(3):198-205

Monthly variations in meat yield and biochemical composition of Mediterranean mussels on lantern nets were investigated from May 2005 to May 2006, in Sinop, south of the Black Sea. Dry weight condition index was between 2.66 and 7.10% with a mean of 4.86 ± 0.36%. Meat yield was maximum (26.69%) in March and minimum (17.43%) in October. Moisture values were between 78% (in June) and 86% (in April). Protein content in dry weight of mussels reached the highest value in February (74.64%) before the spawning time. Lipid value was maximum (18.03%) in May 2005.  相似文献   

Electric current in polymer solution jet and spinnability in the needleless electrospinning process     

Funda Cengiz-Çallioğlu  Oldrich Jirsak  Mehmet Dayik 《Fibers and Polymers》2012,13(10):1266-1271

In this study, the electric current of polymer solution jet was measured during a needleless rod electrospinning process using memory oscilloscope recording. According to the results, electric current of solution jet increases as the polyurethane (PU) and tetraethylammonium bromide (TEAB) salt concentration increase. Especially at 17.5 and 20 wt% PU concentrations, electric current increases dramatically with TEAB concentration. Also, there is a strong relationship between the electric current in the solution jet, spinnability and the spinning performance of the roller electrospinning. Thus, the spinnability of polymer solutions can be easily estimated using this simple method.  相似文献   

Embryonic and larval development of black skirt tetra (Gymnocorymbus ternetzi,Boulenger, 1895) under laboratory conditions     

İhsan Çelik  Pınar Çelik  Şükran Cirik  Mert Gürkan  Sibel Hayretdağ 《Aquaculture Research》2012,43(9):1260-1275

The embryonic and larval development of black skirt tetra, Gymnocorymbus ternetzi, are described under controlled laboratory conditions. In addition, major histomorphological changes and the allometric growth patterns during larval development have been described. The laboratory‐reared broodstock, that is 1 year of age, were spawned. Hatching occurred 20–21 h after spawning at 24 ± 0.5°C. The cleavage was finished in 2 h and the early blastula stage occurred at 2:04 hours after spawning. The gastrulation started at 3:20 hours and 30% epiboly was observed at 3:34 hours after spawning. Eight‐somite stage was observed at 08:33 hours. And embryonic developmental stage was completed at 21 h after spawning. The newly hatched larvae were 1442 ± 14.3 μm in mean total length (TL). The mouth opened at 3 days after hatching (DAH). The yolk sac had been totally absorbed and the larvae started to swim actively within 3–4 days. Notochord flexion began at 11 DAH. The metamorphosis was completed and the larvae transformed into juveniles at 32 DAH. In this paper, the full developmental sequence from egg to juvenile of G. ternetzi is described for the first time.  相似文献
