Afficher plus [+] Moins [-]Detection and Molecular Characterization of ‘Candidatus Phytoplasma Trifolii’, a Member of the Clover Proliferation Grup, Infecting Tomato Plants from Iğdır Province in Turkey
2020
Mustafa Usta | Abdullah Güller
The tomato plant exhibiting leaf rolling, witches’ broom, distorted and elongated flower’s sepals in Iğdır province, Turkey, was observed. Total DNA extraction was performed from the symtomatic fresh tomato sample. All DNAs were subjected to Direct and Nested polymerase chain reaction (PCR) with universal primer sets that amplified the 16S rRNA of phytoplasmas. PCR products were purified from agarose gel and cloned into the pGEM T-Easy cloning vector. Recombinant plasmids were introduced into the prokaryotic cloning bacteria by electroporation. Plasmid isolation was performed by selecting one of the positive clones randomly and sequencing was performed by Next Generation Sequencing (NGS). Sequencing results revealed that the 16S rRNA gene associated with phytoplasma was 1251 nucleotides in size, and this sequence was denominated as ‘Iğdır 10’ isolates and recorded in the GenBank under the MT344968 accession number. The virtual restriction fragment length polymorphism (V-RFLP) and phylogenetic analysis of the 16S rDNA sequence confirmed that the cause of disease in infected tomato plants was 'Candidatus Phytoplasma trifolii' ('Ca. P. trifolii') (16SrVI-A, Clover proliferation group), with a 1.00 similarity coefficient. This present study is the first report of ‘Ca. P. trifolii’ and its nucleotide sequence analysis in naturally infected tomato in Iğdır province.

2020
Sertaç Güngör | Ceren Akyüz
The primary purpose of this study is whether gender, which is a culturally and socially defined concept, affects the perception of landscape architecture. Secondly, it is aimed to determine the preferences of the designs created in landscape architecture studies according to gender and to guide the questionnaire results in the creation of areas suitable for user requests during the design phase. The concept of admiration, preference and accompanying beauty, the effect it has on people according to gender, show various differences. These differences lead to perceptual selectivity in terms of colour, texture, form, functional and aesthetically depending on gender. Therefore, tastes and preferences are not expected to be a single judgment but to vary. Since there is no possibility of face-to-face surveys due to the current Covid-19 outbreak, online surveys were conducted on 220 people who can be reached in professional groups on social media. In the content of the questionnaire, the landscape design criteria and design elements were handled, and the visuals and preferences selected for each definition were directed to the participants as questions. According to the evaluated results, differences occurred in perceptual preferences depending on gender. In addition to the fact that there was no statistically significant difference between the preferences of women and men in terms of design criteria and elements, the preferences of both groups were combined in natural or close to nature forms. Considering the proportions, there was no obvious difference in design perceptions preferred by gender.

Angela Ebere Obetta | Ridwan Mukaila | Ogochukwu Gabriella Onah | Chukwuemeka Chiebonam Onyia
Processing of melon plays a significant role in the livelihood of rural women as it serves as their major occupation. Despite its significant role, the women processors were faced with some challenges. This study, therefore, identified the challenges faced by women in melon processing in Enugu-Ezike Agricultural Zone of Enugu State, Nigeria. Primary data were collected from 80 respondents using a structured questionnaire coupled with an interview schedule and analysed using descriptive statistics. The results showed that the majority of the women processors were advanced in age, well experienced, do not belong to a cooperative society, and relied strictly on processing melon as their source of livelihood. They had an average income of N286,400 (USD 751.71) per annum. Low capital, poor credit facilities, high transportation cost, price fluctuation, rapid deterioration, low supply of melon, poor storage facilities, high cost of processing machine, and breakage of seed were the identified constraints facing them. The study recommended that the women processors should form a cooperative society which will help in financing and easy marketing of their products. Also, the government should provide financial assistance, good storage facilities, and subsidized melon processing machine to increase efficiency.

Mustafa Bayram | Yasemin Gök
Syria is a middle-income developing country with an economy that heavily depends on the food and agricultural sectors. However, with the recent Syria crisis/war, which started in March 2011, Syria’s food and agricultural industries have badly been affected. While the most of the processing factories and agricultural facilities such as industrial zones, food plants, greenhouses, irrigation canals and pumps have been damaged in the conflict areas, this resulted in a huge recession in the food and agricultural productivity of Syria. It is estimated that this will impact the country to meet the future food requirements as well. In this study, the agricultural and food potential of Syria was analysed based on agricultural area, available lands, irrigation, food sectors etc. for the future planning food policies.
Afficher plus [+] Moins [-]Quality Changes in Sous-Vide Cooked Meat
2020
Meltem Serdaroglu | Esra Derin
Sous-vide process is a cooking method for vacuumed products which are placed in a water bath or steam oven at controllable low temperatures and specific long times. This technique is widely used for cooking of meat and meat products which have limited shelf life throughout cold storage. Temperature, time and vacuum parameters used in sous-vide method are effective factors on meat quality. It is realised that meat tenderness increases with this technique due to cooking is performed at low temperatures. For the same reason, more water is retained in the texture and cooking losses are reduced. In addition to this, it is appeared that the sous-vide method provides protection of nutrient components that are water-soluble and/or adversely affected by high temperature applications, so that this method increases the nutritional value of meat. On the other hand, use of controllable cooking temperatures facilitates to reach targeted core temperatures in meat. With the help of homogeneous distribution of heat, even colour formation on meat can be observed. Oxidative reactions in the product are limited by the application of vacuum, so that product quality can be preserved for a long time. The risk of food safety as a result of low temperature applications in sous-vide cooking is eliminated by increasing cooking times. In this review, it is aimed to inform about effects of sous-vide cooking technique on meat quality under the heads of; texture, juiciness and cooking losses, colour, flavour, lipid and protein oxidation and microbial quality. Besides, the effects of sous-vide cooking method on quality parameters, different effects of sous-vide and traditional cooking methods on quality parameters were deeply discussed.
Afficher plus [+] Moins [-]Effect of Alfalfa Meal and Enzyme Use on Performance, Carcass and Intestinal Parameters in Growing Quail Rations

Mahmut Mutlu | Alpönder Yıldız
This study was carried out to determine the influence of different levels of alfalfa meal and the addition of enzyme on performance, carcass and intestinal parameters in growing quails. Japanese quails (n=240), 1 days of age, were divided into 6 dietary treatment groups and the experiment lasted for 5 weeks. In each experiment group there were 4 replicates, and in each replicates there were 10 chicks. Six diets, arranged a factorial design with three alfalfa meal levels (0, 2.5 and 5.0 %) and two levels of added enzyme (0.0 and 1.0 g/kg) were used. The treatments did not effect on the body weight, feed intake and feed conversion ratio. However, relative liver, leg+back, intestine weights and crypt depth were significantly increased, and relative heart and breast weights and villus width decreased by dietary alfalfa meal levels. The addition of enzyme to diets containing alfalfa meal did not affect the performance and carcass parameters, but reduced the intestinal histomorphology parameters in quails. According to the results obtained from the experiment, it can be said that the use of alfalfa meal in growing quail diets did not affect the performance, but the use of alfalfa meal at the level of 2.5% in the diet promotes intestinal development.

Gökhan Baktemur | Zeynep Dilan Çelik | Ecem Kara | Hatıra Taşkın
Shiitake mushroom (Lentinula edodes (Berk.) Pegler) popular as both edible and medicinal, is one of the most cultivated and consumed mushroom species in the world. Cultivation of this mushroom on different agricultural wastes has been experimented in many studies until today. Nevertheless, agricultural waste trials are going on as agricultural production patterns of the countries are different. In this study, volatile aroma composition of shiitake mushroom produced on different agricultural wastes (wheat stalk, wheat bran, peanut shell, corn cob and vine pruning waste) was compared. Oak sawdust was selected as control because of its common use in literature and substrate materials were mixed at different ratios. In addition, some substrate mixtures were prepared with poplar sawdust. Volatile compounds of the shiitake mushroom were determined by using headspace-solid phase microextraction (HS-SPME) technique combined with Gas Chromatography-Mass Spectrometer (GC-MS). At the end of study, 41 volatile compounds were detected and dimethyl trisulfide, benzaldehyde, dimethyl disulfide, 1-octen-3-ol and 3-octanone were found to be dominant volatile components. Flavour and fragrance of mushrooms are dependent on many volatile aroma compounds and their proportions. While the concentration of eight-carbon components and hydrocarbons was found the highest by using wood straw, amount of sulphur containing compounds and alcohols increased by agricultural wastes in this study. In addition, corn waste positively affected aldehyde compounds.
