Ülkemize özgü geleneksel fermente bitkisel ürünlerimizden biri olan şalgam suyu üretimi ile ilgili standart bir teknik ve kullanılan sıcaklık bulunmamaktadır. Bununla beraber Adana, İçel, Hatay gibi illerimizde oldukça popüler olan şalgam suyu üretiminde genellikle endüstriyel boyutta geleneksel yöntem adı verilen bir yöntem kullanılmaktadır. Bu çalışmada, şalgam suyu üretiminde geleneksel yöntem kullanılarak farklı sıcaklığın mikrobiyal flora üzerine etkisine bakılmıştır. Bu amaçla öncelikle hamur fermantasyonu gerçekleştirilerek ekstrakt elde edilmiş ve ardından diğer hammaddeler ile karıştırılarak havuç fermantasyonu farklı sıcaklıklarda (10°C, 22°C ve 35°C) gerçekleştirilmiştir. Denemelerde fermantasyon sırasında ortamda bulunan laktik asit bakterileri (LAB), toplam mezofil aerob bakteri (TMAB), koliform bakteri (KB) ve toplam maya (TM) sayıları belirlenmiştir. Fermantasyonun başlamasıyla beraber LAB, TMAB ve TM sayılarında artış ve KB sayısında bir azalma gözlenmiştir. İlave olarak farklı sıcaklık uygulaması, havuç fermantasyonunun süresi üzerinde de önemli derecede etkiye neden olmuştur. Sıcaklık arttıkça fermantasyon süresi kısalmıştır.

Five CMS lines were crossed with 49 genotypes as ‘testers’ to get 245 hybrids. The 245 hybrids were subjected to pollen and spikelet fertility analysis. Among the 245 hybrids 21 hybrids were expressed as restorers, 24 as maintainers, and 200 intermediate types. Six tester’s viz., BR6592-4-6-4, BR6839-41-5-1, IR74052-184-3-3, IR72593-B-3-2-2-2, BR7011-37-1-2, and IR72049-B-R-22-3-1-1 were identified as restorers for highest 2 lines out of the five CMS lines, differently. None of them were found to be restorer for all the five CMS lines. BAU581 was found to be maintainer for four lines except for D.ShanA. Purbachi was found to be maintainer for three lines except for D.ShanA and IR73328A out of the five CMS lines. Out of 245 crosses only 45 crosses contributed directly to the identification of maintainer and restorer. Other crosses were more or, less of intermediate types which indicated neither maintainer nor restorer. It is well known that, pollen fertility is controlled by one dominant gene (RfRf). If pollen fertility is governed by only one gene the product would be either restorer or, maintainer where will be no existence of intermediate types. So, there might be modifier genes in different genotypes which interacted with male sterile nuclear genes that resulted in intermediate male sterility in the crosses.

This study was carried out in Rize province in 2016, on fresh leaf samples collected from an organic tea plantation. In this study, the aim was to determine the effect of pruning age (1st year, 3rd year and 5th year following the last pruning) and diurnal variability on antioxidant activity and dry matter rate in tea leaves depending on shoot periods. When the pruning age was considered, the highest antioxidant activity was obtained from the plants which were in 5th pruning age in the 1st shoot period with 4991,1 μmol FeSO4/g dw. In terms of the same trait, the effect of pruning age on antioxidant activity during the 2nd shoot period was insignificant, while the highest antioxidant activity in the third shoot period was obtained from 1st pruning age with 7229.2 μmol FeSO4/g dw. As a general average, considering intraday collecting time, antioxidant activity in leaves collected in morning (07.00) and at noon (12.00) was very close to each other, while the collected leaves in the evening (17.00) had higher values. The dry matter rates obtained from the 1st, 3rd and 5th pruning ages were 23.45%, 25.23% and 25.45% respectively. When the shoot period was considered, the lowest dry matter rate was 20.17% in the first shoot period and the highest dry matter rate was 28.8% in the 2nd shoot period and high values were obtained from the leaves collected at noon.

Bu çalışmada; Osmaniye’de demir, çelik ve metal sanayi işletmelerinin üç ayrı bölgesinden mesafeye bağlı olarak örneklenmiş toprakları ile bu işletmelerden uzakta bulunan Osmaniye Korkut Ata Üniversitesi kampüs topraklarının bazı iz element [Cu, Mn, Fe ve Zn (mg/kg)] içerikleri ve karbon mineralizasyonu (28°C, 45 gün) karşılaştırmalı olarak incelenmiştir. Karbon mineralizasyonu için CO2 respirasyon yöntemi kullanılmıştır. Tüm topraklarda iz element içeriklerinin sınır değerlerden düşük olduğu belirlenmiştir. Sanayi Tesisleri yakınından örneklenmiş 1 nolu toprağın karbon mineralizasyonu [15,0 mg/C (CO2)/100 g KT] 4 nolu kampüs toprağından [30,0 mg/C(CO2)/100 g KT)] anlamlı düzeyde düşük bulunmuştur. Benzer durum dört toprağın karbon mineralizasyon oranları arasında da gözlenmiş olup Sanayi Bölgesi’nin üç toprağın da yine kampüs toprağından anlamlı düzeyde düşük bulunmuştur. Tüm bu bulgular toprakların karbon mineralizasyonu ve iz elementi içeriklerinin Sanayi Bölgesi’nden uzaklaştıkça değişmediğini; toprakların organik karbon ve azot içerikleri ile pH’larına bağlı olarak değişebileceğini ortaya koymaktadır.

Tricholoma anatolicum H.H. Doğan & Intini is known as the most prized mushroom species in Feke region of Turkey. This mushroom species is collected from Cedar (Cedrus libani) forests and therefore is named as Cedar mushroom in this region. It is collected and consumed by local collectors and also exported to Far East countries such as Japan by exporting companies. Therefore, it is important to investigate the nutritional and medical importance of this species. The aim of this study is to reveal the antioxidant activity of methanol extract in different concentrations (1, 2 and 4 mg/mL) of T. anatolicum H.H. Doğan & Intini collected from Feke district of Adana province of Turkey in 2015. In this study, it was determined that total phenolic content of this mushroom was 56 mg/kg. 2,2-diphenyl-1-picrylhydrazyl (DPPH), nitric oxide (NO) and reducing power (RP) activities given in trolox (µM) and ferric-reducing antioxidant power (FRAP) given in FeSO4 (µM) were found as 449, 180, 337 and 2 at the highest concentration (4 mg/mL), respectively. As a result, it could be suggested that methanol extract of T. anatolicum H.H. Doğan & Intini has significantly antioxidant activity.

In this study, it was aimed to determine the reasons for the waste of bread among consumers in Hatay province and what should be taken for the elimination of these causes. The subjects of this study were the data obtained from 406 consumers selected from the city center. The data were obtained through face to face interviews during the period of May-2017. In the questionnaire, there were questions towards determining the bread consumption habits, consumption preferences and bread waste levels along with the socio-demographic characteristics of the consumers. Cross tabulation and chi-square analysis were used in the evaluation and comparison of the data. It was determined that the amount of bread consumed per person was 278 g/day and 7% of the total family consumption of bread was wasted without any consumption. While the most consumed types of bread are traditional white bread and flatbread, bakeries and groceries are the most common places to buy bread. Consumers usually buy bread twice a day and the main considerations in the consumers’ preference for bread purchase are that the establishments comply with hygiene requirements and that quality materials are used in the bread making process. Staling and bad taste are among the significant issues in bread wastage. Taking future trends in the sector into consideration, producers should pay attention to product quality, production according to health conditions and longer shelf life on bread; depending on consumer awareness. The producers should diversify their production of bread and other bakery products.

The plants can only use the around 50% of the applied nitrogenous fertilizer. It has been observed that the dynamic fertigation applications help to improve the fertilizer effectiveness. In the dynamic fertigation approach, water and plant nutritional elements are calculated and determined according to the plant dry matter generation rate and root volume. Smart agriculture is an knowledge based decision making approach established upon quantification and observations of the changes in each level of production. With this system, saving can be provided by only supplying the plant’s daily need of water and fertilizer and preventing the excess irrigation and fertilizing, so yield increase can be achieved by keeping away the plants from the stress conditions. Agricultural production can be increased five times by irrigation but shortening in water sources and decrease in quality reasoned by fast growing are restricted of irrigation which is the main user of freshwater sources. Increasing the water and fertilizer effectiveness with the smart irrigation techniques which can save water and fertilization management applications are the essential strategies to be able to reach the yield increase in order to supply the growing food needs of developing population and help to minimize the environmental damage. In the study, the researches and applications related to smart irrigation and fertilization were tried to be included in a wide scope and tried to keep a light to obtain higher yield with less water and fertilizer use in agriculture.

This study carried out in 2015 and 2016 to determine phenological, pomological and some technological characteristics of 19 seedless mulberry genotypes of the Malatya Apricot Research Institute. Full-bloom periods of the genotypes varied between 27th of April (Poser 24-07) and 3rd of May (24 MRK 02); start of harvest dates varied between 15th of May (Poser 24-07) and 31st of May (Yediveren 24-08); end of harvest dates varied between 5th of July (Angut 009) and 30th of August (Yediveren 24-08). Fruiting durations varied between 50 days (Angut 009) and 95 days (Gemirgap Dutu 24-05). Of the pomological characteristics, average fruit weights varied between 0.77 g (Angut 009) and 2.46 g (Poser 24-07); water soluble dry matter (WSDM) contents varied between 15.50% (Topu Beyaz 1) and 29.60% (Angut 009). Of the technological characteristics, drying efficiency values varied between 15.79% (44 KE 10) and 39.94% (Angut 009), dry fruit color L values varied between 25.97 (Poser 24-07) and 50.20 (İstanbul Dutu 24-12). Based on present findings, Poser 24-07 genotype was found to be prominent with early fruiting and availability for fresh consumption; Yediveren 24-08 genotype with late fruiting; İstanbul Dutu 24-12 genotype with drying efficiency and Gemirgap Dutu 24-05 and Gemirgap Dutu 24-06 genotypes with their longer fruiting durations. Current findings may be beneficial in mulberry breeding programs.

The relationship between an individual’s actual knowledge and their self assessed knowledge about an issue is an important factor on consumer’s behaviour. The effect of the knowledge factor on consumer decision making is evaluated by two approaches which are objective (real knowledge) and subjective (self assessed) knowledge. In certain studies it was found that in some situations consumers believe they know more than they actually do about a topic; and they may make their decisions based upon the knowledge they assume is correct, whether it is true or not. This study aimed at determining the relationship between the objective and subjective knowledge about GM foods of consumers who live in the Hatay city centre. According to the research results; even though around 70% of the consumers thought that their knowledge about GM foods were ‘’enough, or relatively enough’’, correct response ratios of the four questions that were based on specific knowledge were quite low. In other words, consumers were overconfident about their knowledge of GM foods. Also, there was no correlation found between consumer’s purchase intention and knowledge level.
