In this work, it was aimed to associate CIELAB Scale (L*, a*, b*) with some quality parameters of roughages such as
pH, crude protein (CP) and relative feed value (RFV). To this end, fie diffrent applications; haylages unwrapped on
25th, 40th and 55th days of fermentation, traditional silage unwrapped 55th days of fermentation and degraded haylage
were examined for vetch-triticale (Vicia sativa L. - Triticasecale wittmack) and caramba-berseem clover (Lolium
multiflrum cv Caramba-Trifolium alexandrinum L.) mixtures in the study. The tests were conducted according to
randomized block design with three replications for both forage mixtures. The ΔL and Δb color values and pH, CP, RFV
were signifiantly correlated in the vetch-triticale mixture. The regression coeffients (R2) for ΔL and Δb were 0.68 and
0.79 for pH, 0.40 and 0.38 for CP, 0.63 and 0.70 for RFV, respectively. In the mixture of the caramba - berseem clover,
the regression coeffients for ΔL and Δb were found to be 0.64 and 0.85 for pH, 0.14 and 0.12 for CP, 0.28 and 0.37 for
RFV respectively. In both mixtures, the level of relation between Δa* color value and quality parameters remained very
low. Also, it was obtained that the best roughage in terms of RFV was haylages opened after 55th days. Decreasing the
L*, b* color values by 50% on average after fermentation can be regarded as an indication of roughage degradation and
RFV reduction. From this point view, it can be possible to determine the quality change by following the colors before
and after fermentation of roughage.

In this study, graft compatibility between almond cultivar Lauranne and almond seedling and Rootpac R, Rootpac
90, Rootpac 70 and Rootpac 40 clonal rootstocks was anatomically investigated. The anatomical analysis of scion/
rootstock combinations was performed by taking cross sections for 30 days and 12 months after T-budding in June,
2017. It was determined that, 30 days after grafting, the callus cells developed but cambial continuity has not occurred
between the rootstock and scion tissues in all scion/rootstock combinations. 12 months after grafting, cambial relation
was established, vascular diffrentiation was observed, regular parenchymatic tissue properties and scleroid (petrosal
cell) cells and sclerenchyma bundles were seen in the graft union. There was no problem in terms of rootstock- scion
compatibility in Lauranne almond cultivar which was grafted on almond seedling and some Rootpac clonal rootstocks.

This research was conducted at the breeding station of the Turkish breeding company Agromar A.Ş in the city of Bursa
in Turkey during the 2013 and 2014 growing seasons. Used from within the same heterotic group crossings, 7 donor
materials were obtained during the 2012 winter season in the greenhouse. The inducer line RWK-76xRWS, provided
by University of Hohenheim, Germany, was used for generating haploid seeds. The donor and inducer crossing was
performed during the 2013 summer season. The haploid selection and chromosome doubling were performed during
the 2014 summer season. Seven donors were used for haploid induction which name are DNR1, DNR2, DNR3,
DNR4, DNR5, DNR6, DNR7 respectively, from each donor diffrent amount of ear crosses were performed (DNR1:16
ears, DNR2:10 ears, DNR3:10 ears, DNR4:12 ears, DNR5:11 ears, DNR6:13 ears, DNR7:11 ears). According to the
present study, the average induction rate found ranged from 7.1 to 12.8%, and the average seedling survival rate in the
greenhouse after colchicine application ranged from 57.9 to 77.6%. After transplanting to the fild, 78.3-92.6% of these
plants survived. As a result of this research, the chromosome doubling rate ranged from 22.5 to 48.3% depending on
the donor material. These result indicates that maternal haploid selection visually is easy. Haploid induction rate (HIR)
changes from donor to donor, its mean genotype and environment is effctive for HIR. Average chromosome doubling
rate is lower than other researchers’ results, it is also effcted by genotype and chromosome doubling methods.

In order to investigate the effcts of diffrent sowing dates and humic acid foliar application on some agronomic traits
of six canola cultivars a two-year experiment was carried out in 2015 and 2016 growing seasons. The experiments
were laid out in a randomized complete block design arranged in factorial split plot with three replicates. The factorial
combination of three sowing dates (7th, 17th and 27th October) and two humic acid levels (0 and 0.2%) were allocated
to the main plots and six canola cultivars (HW118, WPN6, HL3721, L14, Tassilo and Natali) were randomized in subplots. The results indicated that the main effcts of experimental factors were signifiant on all studied traits, except for
harvest index. Interaction between sowing date and cultivar was also signifiant on all traits except for branch number
and harvest index. In general, early seed sowing caused the highest yield and yield component as well as oil percentage
and yield. Similarly, humic acid foliar application could increase agronomic traits in canola cultivars. In sum, early seed
sowing and humic acid foliar application are highly recommended in canola production.

Net blotch caused by Pyrenophora teres is an important pathogen of barley plants worldwide. There are two biotypes
of the fungus. Pyrenophora teres f. teres (Ptt) causes the net form of the disease and Pyrenophora teres f. maculata
(Ptm) causes the spot form of the disease. Barley landraces are good sources of disease resistance. In this study, seedling
response of 25 barley landraces obtained from diffrent regions of northwest Iran to 3 single spore isolates of Ptt
and 3 single spore isolates of Ptm were determined under greenhouse conditions. Diffrences in virulence among the
isolates were evident. Some landraces showed diffrent responses to diffrent isolates. Landraces # 9 and # 16 showed
moderately resistant reactions to one isolate of Ptt and showed moderately resistant-moderately susceptible reactions
to 2 isolates of Ptt. Landraces # 7, # 11, # 15, # 17, # 21, # 22, # 23 and # 25 showed moderately resistant-moderately
susceptible reactions to all 3 isolates of Ptt. Landrace # 23 showed resistant-moderately resistant reaction to one isolate
of Ptm and showed moderately resistant reactions to 2 isolates of Ptm. Landrace # 16 showed moderately resistant
reactions to all isolates of Ptm. Landraces # 11, # 15, # 21 and # 25 showed moderately resistant reaction to one isolate
of Ptm and showed moderately resistant-moderately susceptible reactions to 2 isolates of Ptm. Landraces that exhibited
reactions between resistant and moderately resistant-moderately susceptible range could be used as a direct seeding
material to the fild or could be used as breeding materials.

Wild barley (Hordeum spontaneum) is a progenitor of cultivated barley and naturally grows in Turkey. H. spontaneum
genotypes possess superior characteristics for biotic and abiotic stress tolerance factors. In this study, 3 virulent
Pyrenophora teres f. maculata and 3 virulent P. teres f. teres isolates were tested under greenhouse conditions in order
to fid net blotch resistant H. spontaneum genotypes. A total of 104 H. spontaneum genotypes were used. Twenty-six
H. spontaneum genotypes which corresponded to 25% of the genotypes (genotypes numbered 8, 13, 14, 16, 22, 24,
27, 31, 37, 44, 47, 54, 58, 62, 65, 66, 69, 74, 78, 81, 89, 94, 99, 102, 104 and 107) exhibited reactions classifid in the
resistant group to 3 virulent P. teres f. maculata isolates. Eight H. spontaneum genotypes which corresponded to 7.6%
of the genotypes (genotypes numbered 24, 27, 29, 33, 44, 54, 89 and 94) exhibited reactions classifid in the resistant
group to 3 virulent P. teres f. teres isolates. Six H. spontaneum genotypes which corresponded to 5.7% of the genotypes
(genotypes numbered 24, 27, 44, 54, 89 and 94) exhibited reactions in the resistant group to both 6 virulent P. teres
f. teres and P. teres f. maculata isolates. In addition, a considerable number of genotypes exhibited resistant group
reactions to one or two isolates of both forms of the pathogen. These genotypes could be used for developing net blotch
resistant barley cultivars.

House dust mites inhabit human houses, causing allergies and respiratory disease. Of them pyroglyphid mites produce at least 23 allergen groups, affecting millions of people worldwide. We determined the house dust mite fauna in the city of Ordu situated on the Black Sea coast of Turkey. Dust samples were taken from a total of 53 houses in 2013- 2015. The mite family Pyroglyphidae had the highest abundance in our samples, followed by family Chortoglyphidae. The most common species were Dermatophagoides pteronyssinus (Trouessart) and Dermatophagoides farinae Hughes (Astigmata: Pyroglyphidae). These two mite species are main allergen-producing species throughout the world, occurring in all sampled houses in the city of Ordu.

Segmentation is an important part of each machine vision system that has a direct relationship with the final system accuracy and performance. Outdoors segmentation is often complex and difficult due to both changes in sunlight intensity and the different nature of background objects. However, in fruit-tree orchards, an automatic segmentation algorithm with high accuracy and speed is very desirable. For this reason, a multi-stage segmentation algorithm is applied for the segmentation of apple fruits with Red Delicious cultivar in orchard under natural light and background conditions. This algorithm comprises a combination of five segmentation stages, based on: 1- L*u*v* color space, 2- local range texture feature, 3- intensity transformation, 4- morphological operations, and 5- RGB color space. To properly train a segmentation algorithm, several videos were recorded under nine different light intensities in Iran- Kermanshah (longitude: 7.03E; latitude: 4.22N) with natural (real) conditions in terms of both light and background. The order of segmentation stage methods in multi-stage algorithm is very important since has a direct relationship with final segmentation accuracy. The best order of segmentation methods resulted to be: 1- color, 2- texture and 3- intensity transformation methods. Results show that the values of sensitivity, accuracy and specificity, in both classes, were higher than 97.5%, over the test set. We believe that those promising numbers imply that the proposed algorithm has a remarkable performance and could potentially be applied in real-world industrial case.

The aim of this research was to determine the influence of drip fertigation on soil chemical properties and vertical distribution of nutrient in the root zone of three apple orchards planted on soils with different textures (loam, clay loam and sandy loam). The fertigation led to a significant decrease in soil pH, concentration of calcium carbonate (CaCO3) and organic carbon (C). Changes of these parameters were more pronounced in sandy loam soil than in loam and clay loam. Fine textured soils (loam and clay loam) had higher accumulation of available forms of P, K, Fe, Zn, Mn and Cu in the surface layer at 0-10 cm depth, compared to sandy loam soil. The results showed that, despite numerous advantages, drip system of fertigation can lead to negative changes of soil properties and that the sandy loam soils are more exposed, but in the same time more suitable for fertigation due to better vertical distribution of nutrients in a soil profile compared to loam and clay loam.
