Detection of in silico SSR Markers Specific to Uzun and Kırmızı Cultivars in Pistachio Texte intégral
2023
Harun Karcı
In the current paper, it was aimed to detect the SSR markers that can be used in the prevention of confusion that may occur in breeding or nurseries, and directly genetically separating Uzun and Kırmızı pistachio cultivars from other commercial cultivars. A total of genotypes of 16 Pistacia vera species, one P. atlantica, one P. eurycarpa and two P. terebinthus species were obtained from the farmer's orchard in Nizip district of Gaziantep province for genetic characterization. Genetic diversity and clustering analyzes were performed with UPGMA (Unweighted Pair Group Method with Arithmetic Average) and STRUCTURE 2.3.4 programs using the scored SSR loci. Genetic relationship and population structure of genotypes were defined using common and distinct polymorphic PCR fragments. Cultivar-specific markers to be used in identifying and distinguishing the genetic structure of Uzun and Kırmızı cultivars were carried out in the current research. CUPOhBa2127 marker has the highest allele number (Na=10). In addition, 11 out of 25 SSR markers were explained as cultivar-specific SSRs that can distinguish Uzun and Kırmızı cultivars. These markers can be used directly by breeders and geneticists without any preliminary screnning of the markers. A quite serious providence will be achieved in the cost and time that will occur with the preliminary analysis, and thus, the confusion that may occur in large scale orchard establishments or nurseries will be reduced to pretty low levels with DNA analysis.

Iustus Alwis | Sachini Ariyachandra | Ruvini Kamalika Mutucumarana | Ruwini Basnayake
The study described herein aimed to investigate the relationship between perceptions of hormone usage and customer preferences for broiler meat and meat products in Sri Lanka with special reference to Kandy district. A total of 460 respondents from Kandy district were interviewed using a pre-tested questionnaire. The analysis revealed that 85.9% of the respondents believes the fact that the hormones are used in broiler production. Also, 75.7% of the respondents were unaware about the fact that the hormones are totally banned from Sri Lankan broiler production. Around 71.4% believed that the hormones are still being used illegally in broiler production in Sri Lanka. The study also found that the general public (36.2%), was the main source that the respondents perceived this false information concerning hormone use. Similarly, 83.7% believes that these chemical substances create health hazards to human. 76.7% of the respondents strongly believed the fact that the adolescent girls who consume broiler meat regularly during their childhood may experience early puberty. The findings of the present study concluded that three misconceptions of (i) use of hormones to attain high growth rates in broilers (ii) hormones assumed to be present in broiler meat pose health hazards to public and (iii) frequent broiler meat consumption during childhood is accompanying with the early puberty in adolescent girls, do exists. Though the majority of the sample comprises of highly educated professionals, these misinformation were spreaded from the information generated among the general public. However stipulating a valid certification with no added hormone in broiler chicken meat will be helpful in changing the mind-set of general public.

In Ethiopia livestock feed shortage and soil acidity are serious problems. In recent years sweet lupins (white and blue species) were introduced as multipurpose crops in the country. However, there is no information about their nodulation potential. This study was conducted to evaluate nodulation potential of these sweet lupins and their effect on nitrogen (N) and phosphorous (P) content of the soil. Seven lupin varieties were evaluated using factorial arrangement (seven varieties * two inoculations) in a randomized complete block design in two locations for two years. The result showed that effect of inoculation and location was not significant (P > 0.05) on biomass, seed, nodule number and soil parameters. While the effect of variety was significant (P < 0.05) on nodule parameters. Its effect on dry biomass and seed yields was also significant in either of the years. Variety and year had no effect on soil N and P contents. In the first year, blue sweet lupin entries had the highest nodule number per plant, 222 nodules. In the second year similar nodulation performance was observed among species and varieties. Soil N and P were not affected by varieties and inoculation. In addition to their yield advantage, compared to the sweet white entries, blue sweet lupin varieties had high potential in nodulation. Therefore, these introduced sweet blue lupins can be used as multipurpose crops in acidic soils of Ethiopia.

Foods for special medical purposes are specially produced or formulated with the intention of regulating children's diets for specific nutrition applications, and used under medical surveillance. These food should not offer a microbiological risk to human health as well as their compositions. The purpose of this study was the microbiological evaluation of foods for special medical purposes used in children’s diet. For this evaluation, eleven imported foods for special medical purposes that were sold in Ankara-Turkey were analyzed in terms of Salmonella spp., coagulase positive staphylococci, staphylococcal enterotoxin, Escherichia coli, Escherichia coli O157, Enterobacteriaceae, Listeria monocytogenes, and Bacillus cereus. The bacterial examinations were done according to each related EN ISO standart methods. In result of the examination, the microbial growth was not observed on the food samples. In conclusion, the samples investigated have no microbiological risk. Also, consumers should examine their expiration dates during purchase because the expiration dates declared on the foods have showed their microbiological stability.

Drying is the simultaneous transfer of heat and mass, which is defined as the reduction of moisture in food. The aim of the study the drying performances of refractance window drying (95°C), fluidized bed drying (95°C, 2m3/m air velocity), and convective drying (95°C) were examined in the drying of Maraş green pepper (C.annuum). Drying performance was evaluated for effective diffusion coefficient (Deff), activation energy (Ea), Chroma (C) and total color change (ΔE). Drying curves were obtained by recording sample weights in 10-min periods. For the refractance window drying, fluidized bed drying and convective drying the time for the samples to reach 6-7% humidity level according to the wet base was found to be 70, 80 and 110min, and the effective diffusion coefficient was 6.49x10-10, 5.68x10-10 and 4.87x10-10 m2/s the activation energy was 53.54, 54.65 and 55.93kJ/mol, respectively. When the color properties are examined the Chroma value was determined as 18.23, 8.85 and 4.80 and the total color as 15.42, 26.29 and 30.33, respectively. It was seen that the closest value to the fresh product was in the samples dried with a refractance window drying. In the study, it was concluded that the use of a refractance window drying shortened the drying time by 14-36%, increased the effective diffusion coefficient, provided drying with lower activation energy, and better preserved the color quality in the production of dried Maraş green pepper.

Hakan Kartal | Naif Geboloğlu
Sürdürülebilir topraksız tarım için çevre dostu ve yenilenebilir materyallerin önemi her geçen gün artmaktadır. Yeşil ve organik atıklardan elde edilen kompost bu materyallerden biridir. Bu çalışmada elma, üzüm ve domates posalarından elde edilen kompostun topraksız domates yetiştiriciliğinde etkileri araştırılmıştır. Elma, üzüm ve domates atıkları meyve suyu ve salça fabrikalarından temin edilmiştir. Elma, üzüm ve domates atıkları ayrı ayrı kompostlaştırılmıştır. Kompost yapımında ana materyale (2m3) 200 dm3 ahır gübresi, 5 kg kireç ve 5 kg üre ilave edilmiştir. Kompost yapımı 22 hafta sürmüştür. Denemede 9 farklı ortam kullanılmış olup, bunlar; kokopit: perlit (2:1) (Kontrol); domates kompostu: perlit (2:1) (D); elma kompostu: perlit (2:1) (E); üzüm kompostu:perlit (2:1) (Ü); domates: elma: üzüm kompostu: perlit (1:1:1:1) (DEÜ); domates kompostu: kokopit: perlit (1:1:1) (DC); elma kompostu: kokopit: perlit (1:1:1) (EC); üzüm kompostu: kokopit: perlit (1:1:1) (ÜC) ve DEÜ kompostu: kokopit: perlit (1:1:1) (DEÜC). Ortamlar hacim esasına göre belirlenmiştir. Besin solüsyonu çiçeklenmeye kadar 2,0 dS/m ve çiçeklenmeden sonra 2,2 dS/m, pH:5,9 şeklinde uygulanmıştır. En yüksek pazarlanabilir verim elma, domates ve üzüm kompostu + kokopit uygulamasında 286,59 ton/ha olmuştur. Kompost kullanılması pazarlanabilir verimde kontrole göre %39,73 artış sağlanmıştır. Vitamin C kontrolde en yüksek çıkarken, pH ve suda çözünebilir kuru madde miktarı değişmemiştir. Kompost kullanılması domates meyvelerinde çiçek burnu çürüklüğünü azaltmış, yaprak kuru ağırlığını artırmıştır. Sonuç olarak, denemede üzüm ve özellikle elma posasından elde edilen kompostun topraksız tarımda domates yetiştiriciliğinde başarıyla kullanılabildiği ve ticari ortamlardan biri olan kokpite göre daha etkili olduğu anlaşılmıştır.

Triano Cornejo, Ana | Perez Gonzalez, Eugenia | Fernández Del Castillo, Tomás | Ruiz Sinoga, José
The western Mediterranean is an area particularly affected by the effects of climate change, which makes it a hotspot, and it is also an area where there is particular competition for land use, where subtropical crops coexist with traditional crops including vines, olives, and almond trees, and where there is growing demand for urban development and tourism. It is one of the most sensitive to the effects of climate change because of the markedly contrasting extreme events, including heat waves, torrential rains and drought. In this study we analysed changes in land use, torrential events and the effect of rainfall on vegetation cover and soils in two basins, the main objective being to analyse the evolution of land use and water erosion in recent decades. The two basins are similar but have different configurations and contrasting uses. One has steep slopes and is characterized by more typical Mediterranean crops, such as vineyards, while the other has been subject to clearing that has modified the steep slopes, and where there has been a change to more competitive crops, including subtropical crops. The results highlight the continuous increase of irrigated crops and urban areas and a gradual disappearance of rainfed crops, the occurrence between torrential events and the correlation between monthly rainfalls and vegetation cover.

Dietary diversity became a global concern in improving health conditions through the habit of food group consumption by adding health dimension to the issue of food calorie consumption. Access to nutritionally adequate and good quality diet is essential to human health, productivity and work output. However, despite the various concerns by governments all over the world on ensuring that every household can at least provide three square meals per day, food insecurity continues to be a major development problem across the globe. This study assessed the effect of COVID-19 pandemic lockdown on households’ dietary diversity in Jos Metropolis, Plateau State, Nigeria. A multistage sampling technique was used to select 265 households. Data was collected using well-structured questionnaire. The analytical techniques were; Descriptive statistics, Dietary Diversity index and Z-Statistics Test. Gender, age, household size, education, marital status, cooperative membership and access to credit were the socioeconomic characteristics described. Result indicate that 86% of the households had low food dietary diversity while 14% of the households had high food dietary diversity before and after the pandemic lockdown. Similarly, 18% of the households had low calorie consumption while 82% of the households had high dietary diversity before and after the pandemic lockdown. Cereals, legumes/grains, oils/fat, roots and tubers, sugar and honey and meats were the most common food consumed by the households daily before and after the COVID-19 pandemic lockdown. Result further indicate that the pandemic lockdown had effect on the dietary diversity and food consumption patterns of the urban households. It can be concluded that the understanding of the effect of the COVID-19 pandemic lockdown on dietary diversity and food consumption patterns of households is important in developing policy measures such as social safety nets, home feeding programmes, the school feeding programme, conditional cash transfers schemes and improved marketing channels that will help mitigate against households falling into food insecurity during similar pandemic in the future.

This study was carried out to investigate the effects of different sowing times on duration of tasselling, plant height, first ear height, ear length, ear diameter, number of ears per plant, fresh ear yield with husk, fresh ear yield unhusked, and marketable number of ears of different sweet corn (Zea mays L. saccharata Sturt.) varieties in Diyarbakır between the years of 2010-2012. The trial was conducted as split plots in randomised complete blocks with three replications. The main plots were sowing times, and the sub-plots were varieties. The trials were carried out at eight different sowing times (1 April, 15 April, 1 May, 15 May, 1 June, 15 June, 1 July and 15 July) with ‘Merit’, ‘Jubilee’, ‘Lumina’, ‘Vega’ and ‘Sakarya’ composite sweet corn varieties. From the variance analysis of the three-year combined average, the duration of tasselling, plant height, first ear height, ear length, ear diameter, number of ears per plant, fresh husked ear yield, fresh unhusked ear yield and marketable ear number were statistically significant for sowing times and varieties. According to the sowing time × variety interaction, except ears per plant and first ear height values, all other traits were significant. The fresh husked and unhusked ear yields varied between 8541.7-19396.8 kg ha-1 and 5065.0-13485.7 kg ha-1, respectively. The highest fresh husked and fresh unhusked ear yields were obtained from the 15 April sowing time of ‘Vega’ variety. The results state that optimal sowing dates for different varieties of sweet corn could be from 1 April to 1 May, and the most suitable variety to be planted is ‘Vega’ in Diyarbakır conditions.
