Response To Inoculation And Sowing Date Of Soybean Under Bafra Plain Conditions In The Northern Region Of Turkey, Nevzat Uslu, Enver Esendal Jan 1998

Response To Inoculation And Sowing Date Of Soybean Under Bafra Plain Conditions In The Northern Region Of Turkey, Nevzat Uslu, Enver Esendal

Turkish Journal of Agriculture and Forestry

The Bafra Plain (latitude 41 0 35' N; longitude 35 0 56' E) which located surrounding of Kizil Irmak delta in the northern Turkey, has a short plant growing season for spring sowings. However, the soils of the region (about 80 000 ha) may have an important soybean [ Glycin max (L.) Merr.] production potential with using the earliest or mid-earliest cultivars. Field experiments were conducted to determine the optimum sowing date of soybean, and effects of inoculation and sowing date on the yield and yield components. P-9292 soybean cultivar was evaluated either inoculated with Rhizobium japonicum or not inoculated …

Cultivar, Weed And Row Spacing Effects On Some Agronomic Characters Of Safflower ( Carthamus Tinctorius L.) In Spring Planting, Nevzat Uslu, Ali Akin, M. Basri Hali̇tli̇gi̇l

Turkish Journal of Agriculture and Forestry

Safflower ( Carthamus tinctorius L.) can be a potential oilseed crop for the low-rainfall areas of Central Anatolia, Turkey. The purpose of this study was to determine response of safflower cultivars to weed and the row spacing. The experimental design was used a split-split plot arrangement in a completely randomized block with 3 replications. Main plots were cultivars (5-118 and 5-154), sub plots were weed treatment (weed not removed and weed removed manually) and sub-sub plots were row spacing (20, 40 and 60 cm). The hand weeding decreased the weed density by 75.3%, conversely increased the safflower yield by 36.3%. …

Investigations On Repellent And Insecticidal Effects Of Xanthium Strumariuml. On Colorado Potato Beetle Leptinotrasa Decemlineatasay (Col: Chrysomelidae), Suzan Çeti̇nsoy, Ali Tamer, Mete Aydemi̇r

Turkish Journal of Agriculture and Forestry

The repellent effects of the extracts of Xanthium strumariumfruits and leaves dilueted with 1/6, 1/8, 1/10 water (w/v) for fruits and 1/6, 1/8 (w/v) for leaves were investigated with randomised plot design and 25 replicates under laboratory conditions. Insecticidal effect was also studied in laboratory. It was found that insecticidal effect was low, where as repellent effect was quite high. On the other hand, the effect of 1/6 concentration of fruit extract against adult and larvae of Colorado Potato Beetle was investigated under field conditions and the repellent effect was confirmed.

Turkish Journal of Agriculture and Forestry

This study is concerned with the production of haploids of linseed. Anthers of eight genotypes were cultured both on solid and in liquid medium. It was found that callus induction rate was low in both media and also the cultivars significantly affected callus induction rate both on solid and in liquid medium. The cultivar Blue-Chip gave, on average, the maximum (3.67%) callus induction rate on solid medium and the cultivar Antares gave, on average, the maximum (3.35%) callus induction rate in liquid medium. The cultivar Norman produced callus on solid medium but did not produce any callus in liquid medium. …


A Study On The Lipase-Catalayzed Esterification In Organic Solvent, Mustafa Ümit Ünal Jan 1998

A Study On The Lipase-Catalayzed Esterification In Organic Solvent, Mustafa Ümit Ünal

Turkish Journal of Agriculture and Forestry

This study was undertaken to investigate effect of molecular sieves on the esterification reaction between lauric acid and geraniol in isooctane catalyzed by immobilized lipase in a batch and continuous-loop packed-bed reactor. Molecular sieves were used to reduce the inhibitive effect of water formed during the reaction by removing it as it formed. Results in a batch reactor showed that, for the molecular sieves to have a pronounced effect on the performance of the enzyme, a ratio of at least 2:1 with respect to the weight of the immobilized enzyme must be used. It was also found that the ability …

Assessment Of Response To Drought Stress Of Chickpea(Cicer Arietinuml.) Lines Under Rainfed Conditions, Cengiz Toker, M. İlhan Çağirgan

Turkish Journal of Agriculture and Forestry

Totally sixty four chickpea lines were grown for assesment of response to drought stress in the stress and non-stress environments under rainfed conditions. The seed yield of the lines when grown under the non-stress condition increased at a rate of 53% over the in stress condition. The line, FLIP 92-154C, was determinated as the best tolerant line to drought stress environment under the field condition. Also, seed yield strongly correlated with biological yield, harvest index, mean productivity, tolerance to drought stress and drought susceptibility index in the stress environment.

Turkish Journal of Veterinary & Animal Sciences

In this study the data on the coccidia of gallinaceous birds in Azerbaijan were presented. Chickens and pheasants have already been examined earlier concerning the presence of Eimeria and Isospora. Peacocks and quails are studied in this aspect for the first time. The examination of the gallinaceous birds concerning the presence of crytosporidia oocysts has been also carried out for the first time. The results obtained are indicative of the presence of a few coccidian species in the gallinaceous birds which have not been detected in Azerbaijan before.

The Targeting Mechanisms Of Membrane Proteins, Nihat Di̇lsi̇z Jan 1998

The Targeting Mechanisms Of Membrane Proteins, Nihat Di̇lsi̇z

Turkish Journal of Biology

This review describes what is known about the way of insertion and translocation of membrane proteins and the factors that determine these structures. The translocation of proteins across the cytoplasmic membrane in prokaryotes and that across the endosplasmic reticulum membrane in eukaryotes are similar in that both require the sinyal peptide that is attached to the amino terminus of the proteins. In general, mebrane proteins reach their final target via the secretory (Sec) pathway which are called Sec-dependent proteins. However, it has become clear that a few membrane proteins are not involved in Sec-pathway and these are called Sec-independent proteins.

In Vivo Dna Methylation Of Escherichia Colidh5\Alphaand Top10f' Strains By Bacterial Cytosine-5methyltransferase M. Msp1, Öztürk Özdemi̇r, David Hornby

Turkish Journal of Biology

At the chromatin level, methylated CpG dinucleotides are R.Msp1 resistant compared with nonmethylated counterparts. The DNA of two E.coli strains was analyzed following transformation-with bacterial cytosine-5-methyltransferase gene M.Msp1 in mammalian transfection vector pcDNA3. Expression of the M.Msp1 was tested by R.Msp1 digestion. The results suggest that the DNA of both strains was fully methylated at the CCGG sequences, by the active enzyme under the control of T7 and cytomegalovirus (CMV) promoters. Methylated DNA can not be digested and it exhibits higher frag-ment sizes in 1% agarose gel in contrast to the untransformed cell DNAs in vivo.
