Turkish Journal of Veterinary & Animal Sciences

In this study, the potential of nematodes as an alternative live feed for the omnivorous larva of Penaeus indicus (Crustacea: Penaeidae) and the carnivorous larvae of Macrobrachium rosenbergii and Palaemon elegans (Crustacea: Palaemonidae) was investigated. The results showed that M. rosenbergii and P. elegans larvae were unable to consume the nematodes. The larvae of these species fed Artemia for 8 days, displayed normal development and high survival (over 90%), but, similar to the starved controls. The larvae grown on the nematodes had all died by the 8th day of the experiments. P. indicus larvae fed nematodes from stage Protozoea 3 …

Exact Test For Investigation Of Hardy-Weinberg Equilibrium, Bahar Çitak, Tahsi̇n Kesi̇ci̇ Jan 1999

Exact Test For Investigation Of Hardy-Weinberg Equilibrium, Bahar Çitak, Tahsi̇n Kesi̇ci̇

Turkish Journal of Veterinary & Animal Sciences

The use of exact and \chi^2 goodness-of-fit tests to control the hypothesis that a sample represents the population in Hardy-Weinberg equilibrium are explained and compared with each other. These tests were applied for the loci with two, three and four alleles. The reliability of these tests depends on the sample size. The results showed that the exact and \chi^2 goodness-of-fit tests provided almost the same results if the sample size is considerably large. The exact test is, however, more reliable than the \chi^2 goodness-of-fit test when the sample size is small.

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 …

Turkish Journal of Agriculture and Forestry

This research was carried out to determine whether dominant morphological features could be used instead of disease tests as markers of lines resistant to stem rust ( Puccinia graminis tritici Eriks. and Henn.). Of the 13 species used as material in the hybridization program, 9 were non-resistant and 4 were resistant. Experiments were carried out separately, because of the different genetic structure in seedling resistance and adult resistance. It was determined that in view of the morphological characters examined; auricle colour, leaf colour and leaf waxiness in seedling resistance, and grain glumaceouss, spike brittleness and awn dentiness in adult resistance …

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 Jan 1999

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 Jan 1999

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, …
