Maize grain yield is a complicated character which depends on multiple factors. Considering this aspect, we carried out an experiment to estimate the genetic parameters and character association of thirty inbred line in maize during November 2017 to April 2018. The highest genotypic coefficient of variation (GCV) was observed for a Number of kernel row per ear (NKRE), ear diameter (ED), plant height (PH), number of kernels per row (NKR). However, heritability (percentage) exhibited highest for the yield per plant (YP), thousands kernel weight (TKW), cob weight (CW), first ear height (FEH), ear length (EL). The percentage of genetic advance (GAM%) was high for YP, CW, PH, FEH, TKW. Results demonstrated that EL has a significant positive correlation with NKR (r = 0.661**). YP showed significant positive correlation with PH (r = 0.718**). While EL (r = 0.587**), NKR (r = 0.501**), NKE (r = 0.422**), and TKW (r = 0.612**) showed insignificant association with YP (0.718). YP has insignificant association with EL to NKRE (r = -0.0414) and PH to FEH (r = -0.092). Highest and positive direct effect on YP was exhibited by TKW (0.519). Considering all traits, IL-28, performed better followed by IL-9, IL-15, and IL-10. The development of hybrids genotypes, these genotypes have the chance to obtain higher heterosis with high performing crosses.

Bread is a popular food in the world because of its variety and convenience. Currently, studies on the adding probiotics to bread are limited due to the adverse effects of processing, such as baking temperature, aerobic environment to the probiotic bacteria. The objective of this study was to produce probiotic cream bread, in which Lactobacillus acidophilus was microencapsulated with Alginate 2% (A); Alginate 2% + maltodextrin 1% (AM); Alginate 2% + xanthan gum 0.1% (AX); and Alginate 2% + maltodextrin 1% + xanthan gum 0.1% (AMX). Microcapsules were added to the kernel, conducting encapsulation yield investigations, survival in baking, preservation of bread, and in simulated gastric fluid and simulated intestinal fluid conditions after 8 days of storage. The results showed that the addition of xanthan gum enhanced the encapsulation yield, it reached 92.9% and 92.37% in AMX and AX samples, respectively. The viability of L. acidophilus during baking was decreased by 3.64 and 3.75 Log (CFU/bread) in AMX and AM samples, compared to A and AX which were decreased by 4.75 and 4.44 Log (CFU/ bread). In SGF (Simulated Gastric Fluid) and SIF (Simulated Intestinal Fluid) conditions, the AMX microcapsules provide the best probiotic protection among the four tested carriers. The combination of xanthan gum and maltodextrin in alginate matrix, eventually leading to having dual efficiency: First, xanthan gum would act as buffers that reduce acid activity; Second, maltodextrin acting as a protective agent of L. acidophilus against high temperature as well as potential prebiotic that improve the viability of probiotic.

The aim of this study was to find potential PGPR from sub-forest soil located different region soils of Turkey. Previous research indicated that the existing bacteria in arable soil are not capable to represent their individual performance most probably due to the competition. To overcome this phenomenon, soils are collected from sub-forest soil of Adana (Ad), Antalya (An), Hatay (Ha), Isparta (Is), Ordu (Or) and Sivas (Si) provinces. Experiment was carried out on the soil existing in Isparta in a greenhouse condition. Four fast growing bacteria colonies in tryptic soy (CASO) agar medium from each province were isolated and then, each isolate cultivated at liquid CASO broth until they reach 106 cfu ml-1. Experiments were carried out with a total of 24 bacteria including 6 province and 4 bacteria cultures from each region. The effects of those bacteria on biomass development and nutrient uptake of maize (Zea mays) were investigated. Sterile broth was applied treatment defined as control. The results revealed that 23 isolates out of 24 stimulated plants shoot dry weight. The highest value observed in the Or1 and Is4 isolates as 12.8 and 12.7 g plant-1 which around 77% higher than control whereas the lowest was in Or2 as 6.45 g plant-1. Plant nutrient concentrations were also influenced from inoculates where An1, Ad1, Or1, Is1 and Is3 significantly increased macro nutrients uptake where total N, available P, K, Ca and Mg were higher by 19%, 14%, 14%, 59% and 41% over the control, respectively. The Fe concentration was found 48% higher in Ad3 isolate. The Cu, Mn and Zn were the highest in Si3 as 43%, 30% and 31%, respectively. In general 4 out of 24 isolates were selected as promising PGPR for both plant development and nutrient uptake of maize.

This study was conducted to assess the structural and environmental conditions and potential problems of under-cover production systems of Çarşamba town, which constitute about 87,81% of under-cover production potential of Samsun Province through comprehensive literature search and to develop possible solutions towards these problems. Selected facilities were analyzed for their structural characteristics, production techniques, technology use, environmental conditions through surveys, drawings, observations and photographs. Present findings revealed that all of the family type under-cover production systems are composed of individual (single) constructions. Facility owners had quite low level of education and under-cover production systems constituted a significant place in their economic statuses. Under-cover production systems were mostly lack of technology because of financial burdens and unplanned production activities. Ventilation, heating and cooling systems, playing a significant role in control of environmental conditions, were mostly insufficient and relevant design criteria were not mostly taken into consideration. With this study, potential problems were identified, structural and environmental requirements of under-cover production systems were determined, and recommendations were provided to producers accordingly.

This study was carried out in order to determine the effects of Mychorrizal Preparation (MP) applications on final take and root quality in grafted and potted grapevine sapling production. In this research, cuttings of five different Vine rootstocks (140 Ru, 110 R, 41 B, 1103 P and 5 BB) and scions of Narince grape cultivar were used. In addition, 5 commercials symbiotic mychorriza preparations (MP); Roots Deep Gel (RD), Endo Roots Soluble (ER), Myco Apply (MA), Bio-one (BO) and Biovam were applied. Scions were grafted on rootstocks by omega table grafting machine and then grafted cuttings were stored for three weeks at stratification room. The grafted cuttings were planted into polyethylene bags (12 × 20 cm size) containing 1:1 sterile perlite-peat mixture. Grafted cuttings were kept in greenhouse during 2 months for growing. After grapevine final take rates were determined, grapevine saplings were transferred to acclimatization environment. Root fresh and dry weights of grapevine saplings were detected in the first week of September. Research was designed according to completely randomized plot as three replications and as 50 grafted cuttings each plot. At the end of study, it was determined that both MP applications and rootstocks have a significant effect on final take and sapling quality. The ratios of first grade sapling varied from 21.5% to 93.3% in first year and from 10.3% to 79.3% in second year. Effects of MP applications on the total final take ratios differed depending on the rootstocks in both years. MP applications showed significant effect on total final take ratios of 110 R and 41 B in the first year, and total final take ratios of 5 BB, 41 B and 140 Ru in the second year. While the best results were obtained from MA, EN, RD applications in the first year, the highest final take ratios were in EN, RD and BO applications in the second year. The highest value on final take was obtained from 5BB rootstock, while the lowest value was recorded in 140 Ru rootstock. Effect of MP applications on the fresh and dry weight of root changed according to rootstocks.

This study was conducted to determine about the histomorphology of anterior, middle and posterior intestines and pyloric caeca of fifth-generation Black Sea trout (Salmo labrax Pallas, 1814). The adult Black Sea trout were 29 month age and averagely weighted 1106.9±73.88g. Pyloric caeca and intestine tissue of twenty fish were taken in seawater. Intestine was divided into three sections: anterior, middle and posterior. Pyloric caeca and intestine had four layers from the inside to outside: mucosa, submucosa, muscularis and serosa. Muscularis was gradually decreased from the beginning of the anterior intestine to the end of the posterior intestine. While pyloric caeca had the lowest muscularis, anterior intestine had the highest muscularis. The highest villi length was obtained in middle 1, and also posterior intestine had two types of villi as simple and complex villi. Simple villi had lower villi length and fewer villi number. Complex villi, branched out along the intestine, contained a large of simple villi. As a result, the histomorphological structure of the midgut section of the adult Black Sea trout shown an alteration section by section.

This study was conducted to collect, preserve and identify local oat genotypes grown in the Central and Western Black Sea region. Within the scope of the research, 251 local oat genotypes were collected from the places where they were cultivated in Düzce, Bolu, Zonguldak, Karabük, Kastamonu, Ordu, Sinop, Samsun, Amasya and Tokat provinces. The collected genotypes together with 4 standard oat varieties were taken into field trial in Ondokuz Mayıs University Faculty of Agriculture Research and Application field according to Augmented trial design in 2008 and 2009 growing seasons. As a result of the study, it was found that there were significant variations in terms of the parameters examined. Among the genotypes, the growth pattern of the 229 genotypes was perpendicular, The cluster genotypes of 163 genotypes were scattered, 132 genotypes were yellow in color, 157 genotypes were strongly stringy and 154 genotypes had callus hairiness. When the Matrix table was examined, it was found that the local genotypes with semi-horizontal growth pattern were not found in Amasya, Karabük, Kastamonu, Samsun and Tokat locations. In particular, parameters such as growth type, cluster type, color of husk, awn condition and callus hairiness. it provides ease of identification, since it does not affect the environmental conditions. In the light of this information, it is thought that the genetic variation is high in terms of ecology in which local genotypes are collected and will be beneficial for the protection of our genetic resources and for the future of national agriculture.
