Turkish Journal of Agriculture and Forestry
This study was carried out in Yüzüncü Yil University, Faculty of Agriculture, Depertment of Horticulture. In this research, the length and diameter development of 4 apricot forms on seedling rootstocks with one and two development of 4 apricot forms seedling rootstocks with one and two years old were ihvestigated. The length and diameter development on one year old rootstocks were 88.42 cm, 8.87 mm; on two year old rootstocks were 114.17 cm, 11.52 mm, respectively. There were signigicant differences between forms and rootstocks as well.
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.
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 …

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.

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 …

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%. …
