Turkish Journal of Agriculture and Forestry

In this study, isolates of Alternaria alternata f.sp. citri, cause of citrus brown spot, were obtained from Minneola tangelo orchards in Çukurova Region where disease appeared and after pathogenicity tests their resistance to iprodione was investigated. Five of 35 isolates recovered from different orchards were observed as iprodione-resistant . The ED_50 values of these resistant isolates ranged from 61.89 to 109.21 \mug/ml, but the average ED_50 value of iprodione-sensitive isolate was less than 1 \mug/ml. When the orchards where from iprodione-resistant isolates collected were checked in terms of fungicide application program in recent years, it was noticed that iprodione application …

In Vitro Propogation Of Some Species From Orchidaceae Family Existing In The Natural Flora Of Aegean Region, Kubi̇lay Önal Jan 1999

In Vitro Propogation Of Some Species From Orchidaceae Family Existing In The Natural Flora Of Aegean Region, Kubi̇lay Önal

Turkish Journal of Agriculture and Forestry

A total of 21 species belonging to Orchis, Ophrys, Dactylorchiza, Serapias, Aceras, Anacamptis genera, Orchidaceae family, was collected from Aegean Region. Orchis laxiflora, Orchis sancta ve Serapias vomeracea were successfully cultured by means of embryo culture, but the other species did not grow. Tuber production rates of Orchis laxiflora and Orchis sancta were found to be higher in dark conditions at +5°C than normal conditions. For the same species successfully cultured, the optimum transfer time to the soil was august, while the percentage of developing plants was low in spring months.

Technical And Economical Analysis Of Short Distance Koller K 300 Yarder Used For The Extraction Of Timber In Artvin Region, Orhan Erdaş, Habi̇p Eroğlu

Turkish Journal of Agriculture and Forestry

The method used in transportation of raw forest products can be performed in two phases. The first phase is called " the minor transportation" which is the extraction and hauling of the logs from the felling areas to the landings and intermediate depots. The second phase is "the major transportation". This phase covers the hauling operation from landings and intermediate depots to the log yards or the mill yards. The forestry transportation of harvested woods from compartments is the most difficult and the most expensive operation. Since forests are generally located on high and steep slopes of mountainous area in …

Effects Of Temperature And Ripening Stage On The Respiration Rate Of Tomatoes, Ali̇ Batu

Turkish Journal of Agriculture and Forestry

The effects of storage temperature and ripening stage on the ripening rate of freshly harvested tomatoes before storage were determined. Respiration was slower in tomatoes harvested at mature green stage of ripening, and the respiration rate increased until the tomatoes reached to the pink and light-red stages of maturity. The maximum CO 2 production occurred in toma-toes harvested at pink, light-red and red stages of maturity, whereas the minimum O 2 consumption occurred in tomatoes harvested at turning, pink and light-red stages of maturity. The highest levels of ethylene were produced by tomatoes harvested at breaking, turning and pink stages …

Strength Of Individual Soil Aggregates Against Crushing Forces I. Influence Of Aggregate Characteristics, Taşkin Öztaş, Koray Sönmez, Mustafa Y. Canbolat

Turkish Journal of Agriculture and Forestry

This study was undertaken to determine the relative strength of individual soil aggregates of different sizes and shapes against crushing forces. Soil aggregates were placed individually between a clean-fixed flat surface and a flat plate connected to a pocketpenetrometer and crushed under applied stress. The results of this study show that the strength of the aggregates against disruptive forces was directly related to aggregate size and shape. As the aggregate size increased, so did the applied stress required to crush the aggregate. Significant relationships were found between applied stress and the mass, volume, average diameter (D avg ) and geometric …

Comparison Of The Centroid Method And Four Standard Formulas For Estimating Log Volumes, Hakki Yavuz

Turkish Journal of Agriculture and Forestry

Centroid Samling was tested on 21 logs of Ash ( Fraxinus angustifolia subsp. oxycarpa), 38 logs of Spruce ( Picea orien-talis (L.) Link.), and 33 logs of Beech ( Fagus orientalis Lipsky.) all of which were measured in detail. The wolume of each log was estimated using Huber's, Smalian's, Newton, Riecke's, Hosfeld's formulas and Centroid Sampling. These estimates were compared with "true" volume of each log which was determined by aggregating the volumes of measured short sections (1 m.) using Smalian's formula. The mean error of the Centroid estimate of the log volumes was not significant for Fraxinus angustifoliasubsp. oxycarpa, …

Determination Of Hydraulic Performances Of In-Line Emitters, Bülent Özeki̇ci̇, Sefer Bozkurt

Turkish Journal of Agriculture and Forestry

The efficiency of trickle irrigation systems depends directly on the uniformity with which water is discharged from the emission devices throughout the system. Ideally, all emitters in the system should discharge equal amounts of water. One major cause of flow rate difference between two identical emitters from the same manufacturer is the manufacturing variation. In this study, manufacturers' rated discharges and coefficient of manufacturing variation values were compared with tested values for various in-line emitters. Discharge rates from 12 different types of trickle irrigation emitters were collected at six different operating pressure levels. Pressure compensating emitters were tested at 50, …
