Tutum Teorisi Açısından Ülke İmajı, Ürün İmajı ve Tüketici Satın Alma Niyeti
Authors: Şentürk Tolga , Kartal Burak
Published: December 2018

Ülke imajı marka imajında olduğu gibi ürünlerin
dışsal özelliklerinden kabul edilmekte ve tüketici ürün değerlendirmeleri
üzerine etkisi 1960’lı yıllardan beri araştırılmaktadır. Ülke imajı üzerine yapılan
çalışmalarda bugüne kadar pek çok etki modeli ve ölçeği kullanılmıştır. Fakat
son dönemde ülke imajının tüketici ürün değerlendirmeleri üzerine yaptığı
etkileri ortaya çıkarmak için en ideal model olarak tutum teorisi öne
çıkarılmaktadır. Tutum teorisi, tüketicilerin bilişsel ve duygusal
değerlendirmelerinin davranışlarına olan etkisini açıklamada en etkili yöntem
olarak görülmektedir. Araştırmamızda tutum teorisi çerçevesinde ülke imajının
tüketici ürün değerlendirmelerine olan etkisi hem bilişsel hem de duygusal
boyutta araştırılmıştır. Çalışmadan elde edilen bulgulara göre bir ülkeye ait
ürün imajı ile söz konusu ürüne ilişkin satın alma niyeti tutumların bilişsel
ve duygusal bileşeni tarafından ayrı ayrı etkilenmektedir. Özellikle bilişsel
bileşen satın alma niyetini hem doğrudan hem de ürün imajı üzerinden dolaylı
olarak etkilemektedir. Duygusal imajın satın alma niyetine etkisi ise göreli
olarak düşük kalmaktadır.

Gelişmekte olan ülkelerin en temel
ekonomik sorunlarından biride işsizlikle mücadeledir. Ülkeler bu temel sorunu
aşabilmek için farklı iktisadi politikalar üretmekte ve uygulamaktadırlar.
Ülkelerin işsizlikle mücadelede uyguladıkları politikalar birbirlerinden farklı
olsa bile, tek bir amaç vardır o da istihdamı artırıp işsizliği azaltmaktır.
Dış ticaretteki gelişmelerin istihdamı artıracağı yönünde teoride bir beklenti
vardır.  Yapılan bu çalışmada Karabük
ilinde 2006:1-2017:12 dönemine ait dış ticaretteki gelişmelerin istihdama olan
etkisi incelenmiştir. Çalışmada ekonometrik analiz Greatl programında VAR
tekniği kullanılarak çözüm gerçekleştirilmiştir. Çalışmanın temel amacı;
Karabük ilinde 2006:1-2017:12 dönemde ihracat ve ithalattaki değişimlerin, yine
aynı dönemde istihdama olan etkisini analiz etmektir.

Authors: Gökce Cem , Demirtaş Gökhan
Published: December 2018

Bu
çalışmanın amacı, yenilenebilir enerji tüketiminin cari denge üzerine etkisini
panel veri yöntemi ile incelemektir. Bu amaçla 27 Avrupa Birliği ülkesi (Malta
hariç) ve Türkiye’nin 1998-2011 dönemine ait verileri kullanılarak sabit
etkiler ve rassal etkiler modelleri tahmin edilmiştir. Çalışmadaki ülkelerin
çoğunluğu enerjide dışa bağımlılık oranı yüksek ve cari açık sorunu yaşayan
ülkelerden oluşmaktadır. Çalışmanın sonuçlarına göre yenilenebilir enerji
tüketimindeki oransal artış, cari denge üzerinde istatistiki olarak anlamlı ve
pozitif bir etkiye sahiptir. Buna ek olarak ampirik sonuçlar, enerjide dışa
bağımlılık oranının cari denge üzerinde istatistiksel olarak anlamlı ve negatif
bir etkiye sahip olduğunu göstermektedir. Bu sonuçlar, yenilenebilir enerji
yatırımlarının, Avrupa Birliği ve Türkiye için cari açık sorununu çözmede
önemli bir alternatif olduğu anlamına gelmektedir.

Çalışmak
amacıyla gittiği ülkede bir yıldan daha uzun süre kalan göçmenlerin anavatanlarındaki
ailelerine gönderdikleri para olarak tanımlanan göçmen havaleleri, gelişmekte
olan ülkelerin önemli sermaye kaynaklarından biridir. IMF Ödemeler Dengesi ve
Uluslararası Yatırım Pozisyonu Klavuzu’nda (BPM6) “çalışanlara tazminat ve
kişisel tasarruflar” olmak üzere iki ana bileşene ayrılan göçmen havalelerinin
hacmi, 2000’li yıllarla birlikte ciddi artış kaydetmiştir. Göçmen gönderileri;
doğrudan yabancı yatırım, dış borçlanma veya dış yardımlara kıyasla daha
istikrarlı bir yapıya sahip olmasından dolayı özellikle kronik dış açık sorunu
yaşayan ülkelerin bu açığı finansmanında güvenilir bir kaynak olarak kabul
edilmektedir. 2015 yılı Dünya Bankası verilerine göre, dünya genelindeki yaklaşık
600 milyar $ göçmen gönderisinin yaklaşık %75’i gelişmekte olan ülkelere doğru
akmaktadır. En fazla göçmen gönderisi alan ülkeler Hindistan, Çin, Filipinler
ve Meksika iken göçmen gönderilerinin GSYİH içindeki payı dikkate alındığında Kırgızistan,
Nepal, Tacikistan ve Moldova gibi küçük ve yoksul ülkeler ilk sıralara
yerleşmektedir.

Bu
çalışma göçmen gönderilerinin dış ticaret dengesi üzerine etkisini ileri panel
veri analiz teknikleri ile incelemekte ve ilgili literatüre ampirik açıdan
katkı sağlamayı hedeflemektedir. Çalışma kapsamında Bağımsız Devletler
Topluluğu üyesi 6 ülkenin 2002-2016 dönemi verileri kullanılarak dış ticaret
açıklarının finansmanında göçmen havalelerinin etkisi araştırılmıştır. İncelenen
zaman dilimi ve ülke seçimi, verilerin kesintisiz olması ve erişilebilirliği
dikkate alınarak belirlenmiştir. Bu doğrultuda öncelikle panelde yer alan
ülkeler arasında yatay kesit bağımlılığının varlığı araştırılmış ve yapılan
analiz ile paneli oluşturan ülkeler arasında yatay kesit bağımsızlığı olduğu
tespit edilmiştir. Bu bulguya dayanarak değişkenlerin durağanlık analizi ve uzun
dönem katsayı tahmininde birinci nesil yöntemler kullanılmıştır. Pesaran, Shin
ve Smith (1999) PMG (Pooled Mean Group) tahmincisi ile ulaşılan uzun dönem
katsayılar göçmen gönderilerinin dış ticaret dengesini Azerbaycan’da pozitif, Moldova
ve Tacikistan’da negatif yönde etkileyen anlamlı bir değişken olduğunu
göstermiştir

Gelişen bilgi teknolojileri işletmenin tüm
fonksiyonlarını etkilerken denetim fonksiyonu da doğal olarak bu gelişmelerden yoğun
biçimde etkilenmiştir. İç denetimin görevi; işletmeye değer katmak ve işletme
bünyesinde bağımsız olarak danışmanlık hizmeti sunmaktır. Aynı zamanda iç denetim,
işletmenin karşılaşabileceği riskleri önceden belirleyerek üst yönetimin tedbir almasını sağlamalıdır. Bilgi teknolojilerindeki
değişimin ortaya çıkardığı yeni riskler işletmenin
kurumsal yapısını, güvenliğini ve veri gizliliğini tehdit etmektedir.
Bütün bu gelişmeler çerçevesinde, 
yeni risklere karşı iç denetim fonksiyonu da yapısını değiştirirken,
risklerle etkin mücadele için gelişen
bilgi teknolojilerine uuyumlu çalışması gerekmektedir.                                                                        

Sosyal medya, mobil cihazlar, büyük veri ve bulut
bilişim teknolojilerinin işletme sistemlerine entegre olması, işletmelere
sistem verimliliği açısından önemli katkı sağlamakla birlikte yeni nesil
risklerin ortaya çıkmasına neden olmuştur. Nitekim ortaya çıkan bu durum,
işletmeleri riskleri yönetme konusunda zorlamaktadır. Bu çerçevede iç denetim,
gelişen risklerin yönetiminde bilgi teknolojilerinden de yararlanarak işletmeyi
koruma altına alabilecektir .

 Bilgi
güvenliği artık, tüm iç denetçilerin çalışmalarında önem vermeleri gereken bir risk
haline gelmiş ve işletmelerin geleceği tehdit etmektedir. Çalışmada gelişen

Setelah itu, diperoleh 2 subjek gaya kognitif reflektif yang didukung dengan 2 subjek yang memiliki kecenderungan gaya kognitif reflektif dan 3 subjek gaya kognitif impulsif. Hasil penelitian menunjukkan bahwa proses berpikir siswa gaya kognitif reflektif mengalami disequilibrium saat mengerjakan soal karena siswa belum pernah mengerjakan soal non rutin sebelumnya. Siswa gaya kognitif reflektif selalu berpikir dahulu jika dihadapkan dengan masalah atau pertanyaan. Disamping itu, siswa hanya menulis inti jawaban yang pokok saja saat mengerjakan tes pemecahan masalah. Sedangkan siswa gaya kognitif impulsif tidak mengalami disequilibrium saat mengerjakan soal karena sudah pernah mengerjakan soal non rutin. Siswa  cenderung spontan dalam menjawab pertanyaan dan menulis semua ide maupun rencana yang ada dalam pikirannya di lembar jawaban.

A Reversible Protonic Ceramic Cell with Symmetrically Designed Pr2NiO4+δ-Based Electrodes: Fabrication and Electrochemical Features
Authors: Tarutin Artem , Lyagaeva Julia , Farlenkov Andrey , Plaksin Sergey , Vdovin Gennady , Demin Anatoly , Medvedev Dmitry
Published: December 2018

Reversible protonic ceramic cells (rPCCs) combine two different operation regimes, fuel cell and electrolysis cell modes, which allow reversible chemical-to-electrical energy conversion at reduced temperatures with high efficiency and performance. Here we present novel technological and materials science approaches, enabling a rPCC with symmetrical functional electrodes to be prepared using a single sintering step. The response of the cell fabricated on the basis of P–N–BCZD|BCZD|PBN–BCZD (where BCZD = BaCe0.5Zr0.3Dy0.2O3–δ, PBN = Pr1.9Ba0.1NiO4+δ, P = Pr2O3, N = Ni) is studied at different temperatures and water vapor partial pressures (pH2O) by means of volt-ampere measurements, electrochemical impedance spectroscopy and distribution of relaxation times analyses. The obtained results demonstrate that symmetrical electrodes exhibit classical mixed-ionic/electronic conducting behavior with no hydration capability at 750 °C; therefore, increasing the pH2O values in both reducing and oxidizing atmospheres leads to some deterioration of their electrochemical activity. At the same time, the electrolytic properties of the BCZD membrane are improved, positively affecting the rPCC’s efficiency. The electrolysis cell mode of the rPCC is found to be more appropriate than the fuel cell mode under highly humidified atmospheres, since its improved performance is determined by the ohmic resistance, which decreases with pH2O increasing.
Approximating Ground States by Neural Network Quantum States
Authors: Yang Ying , Zhang Chengyang , Cao Huaixin
Published: December 2018

The many-body problem in quantum physics originates from the difficulty of describing the non-trivial correlations encoded in the exponential complexity of the many-body wave function. Motivated by the Giuseppe Carleo's work titled solving the quantum many-body problem with artificial neural networks [Science, 2017, 355: 602], we focus on finding the NNQS approximation of the unknown ground state of a given Hamiltonian $H$ in terms of the best relative error and explore the influences of sum, tensor product, local unitary of Hamiltonians on the best relative error. Besides, we illustrate our method with some examples.
"Network Sentiment" Framework to Improve Security
and Privacy for Smart Home
Authors: Pecorella Tommaso , Pierucci Laura , Nizzi Francesca
Published: December 2018

A Smart Home is characterized by the presence of a huge number of small, low power devices, along with more classical devices. According to the Internet of Things (IoT) paradigm, all of them are expected to be always connected to the Internet in order to provide enhanced services. In this scenario, an attacker can undermine both the network security and the user’s security/privacy.
Traditional security measures are not sufficient, because they are too difficult to setup and are either too weak to effectively protect the user or too limiting for the new services effectiveness.
The paper suggests to dynamically adapt the security level of the smart home network according to the user perceived risk level what we have called network sentiment analysis. The security level is not fixed,
established by a central system (usually by the Internet Service Provider) but can be changed with the users cooperation. The security of the smart home network is improved by a distributed firewalling and Intrusion Detection Systems both to the smart home side as to the Internet Service Provider side. These two parts must cooperate and integrate their actions for reacting dynamically to new and ongoing threats. Moreover, the level of network sentiment detected can be propagate to nearby home networks (e.g. the smart home networks of the apartments inside a building) to increase/decrease their level of security, thus creating a true in-line Intrusion Prevention System (IPS). The paper also presents a test bed for Smart Home to detect and counteract to different attacks against the IoT devices,,Wi-Fi and Ethernet connections .
Free-Flowing Shear-Thinning Liquid Film in Inclined μ-Channels
Authors: Koupa Angeliki T. , Stergiou Yorgos G. , Mouza Aikaterini A.
Published: December 2018

Among the most important variables in the design of falling film microreactors (FFMRs) is the liquid film thickness as well as the gas/liquid interfacial area, which dictate the mass and heat transfer rates. In a previous work conducted in our lab the characteristics of a free-falling Newtonian liquid film have been studied and appropriate correlations have been proposed. In this work the geometrical characteristics of a non-Newtonian shear thinning liquid, flowing in an inclined open microchannel, have been experimentally investigated and design correlations that can predict with reasonable accuracy the features of a FFMR have been proposed. The test section used was an open μ-channel with square cross section (Wo=1200 μm) made of brass which can be set to various inclination angles. The liquid film characteristics were measured by a non-intrusive technique that is based on the features of a μ-PIV system. Relevant CFD simulations revealed that the volume average dynamic viscosity over the flow domain is practically the same as the corresponding asymptotic viscosity value, which can thus be used in proposed the design equations. Finally, a generalized algorithm for the design of FFMRs, containing non-Newtonian shear thinning liquids, is suggested.

Las guías nutricionales incorporan los lácteos como parte de una dieta equilibrada y saludable. En la mayoría de las ocasiones se especifica que los productos lácteos sean preferentemente bajos en grasa o desnatados. La razón que subyace a esta limitación es el aporte de ácidos grasos saturados (AGS) inherente al consumo de grasa láctea.Recientemente se ha planteado que valorar los alimentos según el aporte de nutrientes que contienen de forma aislada conlleva a interpretar de forma limitante sus funciones y propiedades. El conocimiento de la matriz alimentaria permite valorar el efecto sobre la salud de los alimentos en su totalidad al considerar, todos los componentes que contiene, y la interacción tras su consumo.Los productos lácteos son un ejemplo para destacar la importancia de la matriz alimentaria como un determinante del efecto que pueden ejercer los nutrientes del alimento. Los efectos potencialmente nocivos de los AGS sobre la salud cardiometabólica parecen no ser tales cuando se consumen como parte de alimentos con matrices alimentarias ricas en nutrientes como son la leche, el yogur, el queso u otros productos lácteos.Estudios epidemiológicos de grandes cohortes poblacionales seguidas a largo plazo muestran que el consumo de productos lácteos, especialmente de yogur, no se asocia con un aumento del riesgo cardiovascular. Por tanto, no existen suficientes evidencias científicas para recomendar a la población general el consumo de productos lácteos bajos en grasa o desnatados de forma preferente, en lugar de su versión entera.

Authors: Chatterjee Shankar
Published: December 2018

According to the WHO survey conducted in October 2017 carried out across India including 35 cities viz., Bengaluru, Chennai, Cuttack, Delhi, Indore, Jaipur, Kanpur, Kolkata, Ludhiana, Mumbai, Ranchi, Srinagar, Surat and Thiruvananthapuramwomen respondents were contacted to get an idea about issues related to women. It has been revealed that about 43 percent of Indian women did not have access to sanitary essentials at the beginning of periods, while 36 percent felt uncomfortable in buying them with other customers around. Further, according to the survey report around 67 percent women have had to borrow a sanitary essential from a friend, colleague or family member. More than 45 percent women opined that menstruation was still considered a taboo in the society and 36 percent felt uncomfortable while buying sanitary essentials from a chemist shop in the presence of other customers. To address the situation at grassroots level many organizations have been working at different levels like awareness creation, producing of cheap sanitary pads etc. One such organization is Gramalayawhich has been operating in Thottiyam and Thathaiengarpet and Thuraiyur Block in the rural areas and in the slums of Tiruchirappalli City Corporation in Tiruchirappalli District. They are promoting sustainable sanitary pads by producing these through self-help Groups (SHGs). In this article based on a study carried on 1st December 2018, a case is presented.

Published: December 2018

There are so many speeches delivered by such famous people in this world. But, if we are asked to give the point of view about the impact of each speech delivered then the speech from Martin Luther King Jr. will convey the high meaning in term of rethorical speech especially the content and the context about the concepts of repetition found. The speech was on 28th of August 1963, at the Lincoln Memorial, Washington D.C in a verbal ways and its text become the secondary data to be analyzed with much focus on emphasizing phrases, words or sentences. By using the concept of rethoric perspective through repetition such as anaphora, epistrophe and epizeuzis, the researcher wants to know the values behind the repetition. That is why, the analysis is using the descriptive qualitative research on taking the secondary data that has been adapted from the video and the text of the speech itself. The conclusion especially on the ideas of repetition are that Martin Luther King Jr. tries to make sure his audiences about that 1) the repetition is something more that the meaning itself, it is above. 2) The struggle, it is something true, needs to be realized in the real life, and adds the weight of the expection to be equal and free.
A Critical Discourse Analysis on Teachers’ Verbal Feedback Patterns in EFL CLT Classrooms
Authors: Dabiri Asma
Published: December 2018

As providing feedback can have an effective role for the learning process, this study with a critical discourse analysis point of view in social scientific research investigated feedback patterns of four English language teachers on learners’ responses in four English Language institutes with Communicative Language Teaching (CLT) approach toward teaching and learning. In doing so, the classes were observed. The interactions were audio-taped and transcribed. The findings revealed that in providing feedback to learners, teachers gave positive feedback (approving and repetition), interactional feedback and corrective (negative feedback) in classrooms. Positive feedback as approving and repetition were the most type of feedback which the teachers made use of. The findings provide insights into feedback patterns in an EFL context and consequently they set up an argument to critically assess one of the most fundamental principles of CLT approach which is giving positive feedback to learners. Attention should be  directed to EFL teachers’ ideologies in providing feedback to the students to uncover their philosophy of teaching and learning as a clue to detect their criteria in choosing some habits of providing feedback than others and hence to expand this area further.

Impacts of drought stress on crop production can significantly impair farmer’s revenue, hence adversely impacting the gross national product growth. For cowpea [Vigna unguiculata (L.) Walp.], which is a legume of economic importance, effects of drought at early vegetative growth could lead to substantial yield losses. However, little has been done with respect to breeding for cowpea cultivars withstanding drought at early vegetative growth. In addition, previous investigations have focused on how plant morphology and root architecture can confer drought tolerance in cowpea, which is not sufficient in efforts to unravel unknown drought tolerance–related genetic mechanisms, potentially of great importance in breeding, and not pertaining to either plant morphology or root architecture. Therefore, the objective of this study was to evaluate aboveground drought-related traits of cowpea genotypes at seedling stage. A total of 30 cowpea genotypes were greenhouse grown within boxes and the experimental design was completely randomized with three replicates. Drought stress was imposed for 28 days. Data on a total of 17 aboveground-related traits were collected. Results showed the following: 1) a large variation in these traits was found among the genotypes; 2) more trifoliate wilt/chlorosis tolerance but more unifoliate wilt/chlorosis susceptible were observed; 3) delayed senescence was related to the ability of maintaining a balanced chlorophyll content in both unifoliate and trifoliate leaves; and 4) the genotypes PI293469, PI349674, and PI293568 were found to be slow wilting and drought tolerant. These results could contribute to advancing breeding programs for drought tolerance in cowpea.

Begonia montaniformis × Begonia ningmingensis var. bella hybrids have high ornamental potential. Hence, the aim of this study was to determine the optimal conditions for the micropropagation of a Begonia montaniformis × Begonia ningmingensis var. bella F1 progeny by using various concentrations of plant growth regulators (PGRs) and varying light spectra in half-strength Murashige and Skoog (1/2 MS) medium. The results showed that the explant regeneration was optimal when the lamina was incubated in a medium supplemented with 2.0 μM N6-benzylaminopurine and 0.8 μM α-naphthaleneacetic acid (NAA). Under such conditions, 98% of the explants regenerated adventitious shoots after 8 weeks, and 41 buds were produced per explant on average. The mean shoot length was 9.6 mm, and on average, 4.5 shoots per explant were more than 2 mm long. Subsequently, the induced adventitious shoots were transferred into rooting medium consisting of 1/2 MS and various NAA concentrations. After 4 weeks, the shoots subcultured in this medium showed ≈93% root induction and an average of 3.5 adventitious roots per explant. Furthermore, the applied light spectrum significantly influenced shoot regeneration, and optimal results were achieved under an equal distribution of blue, red, and infrared light. The histological sections of shoots regenerated from direct organogenesis were observed through scanning electron microscopy (SEM). Afterward, the rooting adventitious shoots were subcultured in PGR-free medium for 8 weeks. The seedlings were successfully acclimated 4 weeks after being transferred to soil and bloomed after 11 months in a greenhouse. Thus, the PGR composition in micropropagation efficiently shortened the time to blooming from 25 to 16 months.
Influence of Phosphorus in Starter Fertilizer on the Establishment of Tall Fescue
Authors: Liu Bohan , Landschoot Peter J.
Published: December 2018

Phosphorus (P)-containing starter fertilizers are often recommended for establishing new turf, regardless of P levels indicated by the soil test. However, few field studies have been conducted to determine the effects of P in starter fertilizer on the rate of turf establishment. The primary objective of this study was to determine if P in starter fertilizer enhances tall fescue groundcover and growth during establishment on silt loam soil. This 2-year field study was conducted on silt loam soil tilled with a rototiller or core-aerated and vertically sliced. Mehlich-3 P levels ranged from 38 to 270 mg·kg−1. Experiments were conducted during late summer and fall, and all tests were seeded with ‘Bullseye’ tall fescue (Festuca arundinacea Schreb.). Treatments included 49 and 73.5 kg·ha−1 of nitrogen (N) without P, 49 kg·ha−1 of N plus three different rates of P (24.5, 49, and 73.5 kg·ha−1), and a nonfertilized control. Comparisons between groups that received treatment with 49 kg·ha−1 of N without P and treatments with 49 kg·ha−1 N with P revealed few significant groundcover responses to the addition of P. Of 12 groundcover assessments performed during four experiments, contrasts revealed only one instance of a higher percentage of groundcover in response to the addition of P. This occurred during an experiment having a pretreatment Mehlich-3 P level of 38 mg·kg−1. Comparisons indicated greater clipping yields in response to the addition of P in one of the four experiments. This occurred in soil that was core-aerated and sliced with an initial Mehlich-3 P level of 66 mg·kg−1. In most cases, Mehlich-3 P levels at the end of each experiment increased as the P application rates increased. The only instance in which comparisons between treatment with 49 kg·ha−1 N without P and treatments with 49 kg·ha−1 N with P demonstrated a significant leaf tissue response to P during the experiment with soil that was core-aerated and sliced with a pretreatment Mehlich-3 P level of 66 mg·kg−1. When individual treatments were compared, the 73.5 kg·ha−1 N treatment without P produced similar or higher groundcover and clipping yields than all other treatments during all four experiments. This study revealed few groundcover and variable tall fescue clipping yield responses to P additions when applied at rates used for starter fertilizer applications on silt loam soil during late summer and fall. Groundcover and growth responses due to P in starter fertilizers do not appear to be solely related to soil test P levels, and other factors such as the method of establishment (tilling soil vs. core-aerating and slicing the soil surface), environmental conditions, and the N content of soil may be involved.
Mitigating Effect of Glycinebetaine Pretreatment on Drought Stress Responses of Creeping Bentgrass

Turfgrass performance under drought stress is impeded by plant water deficit and oxidative damage, which might be improved by the external application of osmoprotectants. Creeping bentgrass (Agrostis stolonifera L.) is a valuable species for low-cut golf surfaces as a result of its high density and fine texture. However, weak tolerance to drought stress is a primary shortcoming. In this study, the effect of exogenous glycinebetaine (GB) pretreatment on mitigating the damage from drought stress in creeping bentgrass cultivar ‘T-1’ was evaluated. Pieces of creeping bentgrass sod were subjected to four treatments: 1) well-watered control, 2) well watered and sprayed with 100 mm GB, 3) drought stress, and 4) drought stress and sprayed with 100 mm GB. Drought stress resulted in a remarkable decrease in turf quality (TQ), relative water content (RWC), and chlorophyll content, with significant increases in superoxide anion content (O2–), malondialdehyde (MDA) content, superoxide dismutase (SOD), catalase (CAT), and peroxidase (POD) activity. In contrast, pretreatment with 100 mm GB decreased the O2– and MDA content in water-stressed plants, and increased turf quality, chlorophyll content, SOD, CAT, and POD activity. Meanwhile, the expression level of the psbA, SAMS4, CMO, and ACS1 genes in leaf samples collected during the drought-stress stage was elevated in GB pretreatment. Notably, SAMS4 gene expression in GB pretreatment was significantly greater than in the untreated GB groups subjected to water stress. These results suggested that GB could mitigate the adverse effect of water stress on creeping bentgrass. The amelioration related strongly to the maintenance of the antioxidant enzyme system, accumulated endogenous compatible metabolites, and the elevation of gene expression levels. These findings lead us to conclude that GB pretreatment could be used as an ameliorative agent for creeping bentgrass against the deleterious effects of water stress.
