Effect Of Paclobutrazol On Vegetative Growth And Fruit Quality Of Some Peaches Grown Insamsun, Şükriye Kurnaz Bi̇lgener, Hüsnü Demi̇rsoy, Neriman Beyhan
Turkish Journal of Agriculture and Forestry
This research was carried out in Çarsamba, Samsun during 1991-1993 by using Paclobutrazol which is a growth reter-dant, three times in a year (Spring, Summer and Autumn) to Cardinal, Redhaven and Glohaven peach varieties. It was also applied from the soil in spring. It was found that the application of Paclobutrazol from the soil was more effective than the leaf application. It's application in fall did not affect the vegetatif development. The spring and summer applications of it showed similiar effects. Application Paclobutrazol at a concentration of 1000 ppm to leaves was effective on vegetative development. Application of paclobu-trazol to …

Different amounts of sodium ascorbate (0, 150, 300 and 450 mg/kg) were used in curing stage of Turkish pastırma production and the effect of sodium ascorbate was investigated on some quality characteristics of pastırma. It was observed that there was no effect of sodium ascorbate on pH and penetrometler value of pastirma. Sodium ascorbate caused to decrease of TBA-value and residual nitrite content (P
Development Of The Downy Mildew Pathogen Bremia Lactucae Ontransgenic Lettuce Expressing A Bacterial \Beta-1,3-Glucanase, Yeter Dede
Turkish Journal of Agriculture and Forestry
A \beta-1,3-glucanase gene from Arthrobacter sp. driven by the 35S promoter was singly transformed into two lettuce cultivars, Cobham Gree and Diana, using the binary vector system of Agrobacterium tumefaciens. Tansformation was confirmed by using Southern and Northern analysis, Npt II enzyme assays and segregation of resistance to kanamycin. Transgenic plants were infected with the letuce downy mildew fungus, Bremia lactucae which contains \beta-1,3-gluncan in its cell wall and alternations in the development the fungus could easily be monitored. Transgenic plants inoculated with B. lactucae showed different levels of resistant responses compared to the control and they were examined microscopically.
Genetic Relationships Of Turkish Bread Wheat Cultivars, Nusret Zenci̇rci̇
Genetic Relationships Of Turkish Bread Wheat Cultivars, Nusret Zenci̇rci̇
Turkish Journal of Agriculture and Forestry
Forty-two bread wheat cultivars released up to 1990 in Turkey have been investigated in order to understand their genetic relationships. Correlation, regression and principal component analyses have been applied to cultivar-to-cultivar parentage coefficients and similarity indices based on pedigree data. Correlation and regression analyses between cultivar-to-cultivar parentage coefficients and similarity indices have shown higher relationships implying that both estimates could be used interchangeably to predict genetic relationships in cultivars. Principal component analyses failed to group cultivars clearly, but some subgrouping were obtained.
A State-Dependent Model Of Forest Floor Development, Ertuğrul Bi̇lgi̇li̇
A State-Dependent Model Of Forest Floor Development, Ertuğrul Bi̇lgi̇li̇
Turkish Journal of Agriculture and Forestry
A state-dependent, dynamic forest floor development model is presented. The model considers litterfall as input. The decomposition of the litter was modelled as influenced by the quality of litter and miccroclimatic conditions (temperature and moisture). Microclimatic conditions were determined based on weather data and stand structure. The predictions of the model compared with an independent data set suggested that the model functions realistically under a range of weather and stand conditions. The resulting model should be valuable in the prediction of fire behavior.
Effects Of Temperature And Time Of Harvest On The Growth Andyield Of Aubergine ( Solanum Melongena L.), Ahmet Kürklü
Effects Of Temperature And Time Of Harvest On The Growth Andyield Of Aubergine ( Solanum Melongena L.), Ahmet Kürklü
Turkish Journal of Agriculture and Forestry
An experimental study was conducted to define the response of aubergine to different temperatures in controlled greenhouses. Set temperatures of the greenhouses were 14, 18, 22, 26 and 30°C. In terms of vegetative growth, the plant response was the highest to the highest temperature then gradually decreasing for the lower temperatures. This was in contrast with the fruit development since as the temperature decreased from 30°C, mean fruit weight and size increased, and the total fruit yield was highest in 22°C which indicated an optimum temperature. However, there was no optimum for vegetative growth. This was found, by using a …

Issues Related To Marketing And Extension For Sustainable Agricultural Production In Turkey, Sedef Akgüngör, Taner Kumuk
Issues Related To Marketing And Extension For Sustainable Agricultural Production In Turkey, Sedef Akgüngör, Taner Kumuk
Turkish Journal of Agriculture and Forestry
Sustainable agriculture, although a difficult term to define operationally, includes the practice of low input agricultural production technologies. An important condition to adopt these technologies is the access to markets for low input agricultural products. Ability to market these products at profitable prices would provide incentives for farmers to adopt the necessary methods. Contract farming is considered to be an effective means to introduce new production technologies to the farmers by providing assurance on prices and markets for agricultural products. Public extension agencies in developing countries may therefore be concerned to direct their efforts to introduce contract farming models to …

Some Factors Affecting On Determination And Measurement Oftomato Firmness, Ali Batu
Some Factors Affecting On Determination And Measurement Oftomato Firmness, Ali Batu
Turkish Journal of Agriculture and Forestry
Firmness is one of the most important factor for determination of tomatoes quality. Distructive measurement of tomato firmness is one of the evaluation methods of fruit firmness. The Universal Instron is most common used machine for measurement of most adeqequate fruit firmness. During destructive measurement of firmness considedation of force or deformation values as a firmness of fruits could give incorrect result and taking epicarp strength over deformation values is more accurate to concern the firmness of tomato. Two of possible minimum firmness limits were suggested for tomato fruits at the point of retail marketing or using at home. All …
Sorption Of Aldicarb Sulfoxide By Samples Of Some Calcareous Soils From Turkey, Kemal Y. Gülüt, Mahmut Sayin
Sorption Of Aldicarb Sulfoxide By Samples Of Some Calcareous Soils From Turkey, Kemal Y. Gülüt, Mahmut Sayin
Turkish Journal of Agriculture and Forestry
Sorption of aldicarb and aldicarb sulfoxide was investigated spectrophotometrically on 16 soil samples. Ten of them were from the Çukurova region. The results showed that organic matter is the single soil property to give correlation with sorption of aldicarb. Clay minerals are also important in sorption but their effect is masked by fine carbonates and organic matter. CaCO 3 sorbs aldicarb weakly. Aldicarb sulfoxide was also sorbed by soil constituents very weakly.

Effects Of Short Trem High Carbon Dioxide Treatment On Tomato Ripening, Ali Batu, A. K. Thompson
Turkish Journal of Agriculture and Forestry
Tomato ( Lycopersicon esculentum Mill.) fruits (Cv Criterium) were harvested at the mature green stage and stored at 13°C in controlled atmosphere (CA) conditions for 1, 3 and 5 days. The CA conditions were 5, 10, 20, 40 and 60% CO 2 all with 5.5%O 2 plus air as control. The tomatoes were then stored at 20°C in air until they were fully ripe. At that time colour, firmness, titratable acidity, total soluble solids (TSS) and days to ripening were measured. Fruit exposed to CO 2 for 5 days subsequently ripened more slowly than those exposed only one day. The …
