Durmuş Çetinkaya
Plantation forestry primarily aims to enhance the production of high-quality timber. This research focuses on evaluating the effect of various climatic factors (such as relative humidity, annual precipitation, average, minimum and maximum temperatures) on the growth parameters (including tree height, breast height diameter and base diameter) of Taurus cedar (Cedrus libani A. Rich.) and Anatolian black pine (Pinus nigra Arn. subsp. pallasiana (L.) Holmboe). This study was conducted in two adjacent plantations established in 1995, with data collected over a three-year period (2022-2024). To assess growth patterns, 30 trees from each plantation were randomly selected and monitored. Climatic data were sourced from Türkiye’s general directorate of meteorology and climatology. Analysis of variance (ANOVA) revealed that growth and climate parameters were statistically similar (p>0.05) for both species, except for tree height, which showed significant differences in Taurus cedar. The Spearman rank correlation analysis identified a strong and statistically significant relationship (p<0.05) between temperature variables (minimum, maximum, and average) and the growth traits of both tree species. On the other hand, relative humidity and annual precipitation showed no significant correlations (p>0.05). The findings underscore the critical role of temperature in influencing tree growth within plantation forestry, offering valuable insights for sustainable forest management practices.

Aslı Aksoy | Çağıl Suleymanzade
Bread is among the most commonly consumed foods in daily diets around the world. It is known that breads produced with sourdough or different cereal flours have positive effects on health. Consumer demand for these types of bread is steadily growing. One key factor influencing bread consumption is their sensory qualities. The aim of our study was to assess the sensory properties of sourdough breads made with various cereal flours and a buckwheat (pseudocereal) substitute. For this purpose, six types of sourdough breads were produced with durum (yellow) wheat, wheat, rye, einkorn, wheat germ flours and buckwheat flour as a grain substitute, and these bread varieties were scored between 1-5 by 9 trained panelists according to loaf and crust appearance, crust thickness, crust color, crust odor, crumb appearance, crumb porosity, crumb color, crumb elasticity, chewability, odor, taste, and general appreciation features. As a result of the evaluation, in terms of general appreciation, the average scores of the bread varieties, from the most to the least appreciated, were determined as buckwheat (Fagopyrum esculentum) bread (4.017), durum wheat (Triticum durum) bread (3.811), wheat (Triticum aestivum) bread (3.685), einkorn (Triticum monococcum) bread (3.102), wheat germ bread (3.076) and rye (Secale cereale) bread (3.008). Additionally, when the average total scores were reviewed at the end of the evaluation, it was found that the breads were rated at least 2.5 points (medium), which is above average. Therefore, it was concluded that breads produced with sourdough by substituting buckwheat, durum wheat, einkorn, wheat germ and rye flours could serve as a good alternative to sourdough wheat bread for healthy nutrition by gaining consumer approval.

The most complex microhabitat is the rhizosphere, which is composed of a varied alliance of archaea, fungi, bacteria, and eukaryotes as well as an interconnected network of plant roots and soil. Crop yield and growth are directly affected by rhizosphere conditions. Plant development and yield were enhanced under nutrient-rich rhizosphere conditions. Most soils that require nurturing before or at the time of next harvest are drained by extensive agriculture. Fertilizers are the primary source of nutrients for crop. However, their extensive and unchecked use seriously threatens ecosystem stability and agricultural sustainability. These toxic substances accumulate in the soil, leak into water, and are discharged into the atmosphere, where they stay for decades and impart a vital risk to the ecosystem as a whole. The rhizosphere of plant growth-promoting rhizobacteria (PGPR) transforms a variety of vital nutrients such as nitrogen, phosphorus, zinc, and others that are unavailable to plants into forms that they can use. In order to interact with the valuable or pathogenic counterparts in the rhizosphere, PGPR produces a variety of hormones such as auxin, cytokinin, gibberellin, antimicrobial agents, secondary compounds, cell lytic enzymes, chitinases, proteases, hydrolases, stress- releasing materials 1-Aminocyclopropane-1-carboxylate deaminase, chelating siderophores, and certain signaling substances such as N-acyl homoserine lactone. PGPR can be used for rhizosphere engineering, which has several uses beyond crop fertilization, development of plant growth, sustainability, and environment friendly agriculture. There is an increasing concern regarding stress-resilient plant growth promoting. microorganisms (PGPM). This review paper covers the three elements of rhizosphere engineering with a particular emphasis on PGPM and how it might promote the appropriate use of rhizosphere engineering particularly in hosts, as an important aspect of environmentally conscious farming.

Fadime Begüm Tepe | Tolga Kağan Tepe
This study investigated the impact of various drying techniques and ultrasound pretreatments on the drying kinetics, rehydration properties, energy efficiency, and quality parameters of apple slices. Apples were dried using hot-air drying at 55 °C and 65 °C, and intermittent microwave drying at 240 W and 400 W. US pretreatment was applied at acoustic densities of 60 and 80 W L⁻¹ prior to hot-air drying to assess its effect on mass transfer and quality. The drying behavior was modeled using both thin-layer mathematical models and artificial neural networks. Results revealed that US pretreatment significantly enhanced the drying rate and reduced drying time and energy consumption, particularly at higher acoustic density and temperature, while intermittent microwave drying achieved the shortest drying durations and lowest energy consumption. Among the models, the Midilli and Kucuk model best described the thin-layer drying data, although ANN models provided superior predictive performance across most conditions. Rehydration ratio was positively influenced by US pretreatment at lower temperatures but was adversely affected at higher temperatures and higher microwave power levels due to structural damage. Total phenolic content and antioxidant activity were preserved or enhanced by microwave drying, whereas US pretreatment showed no clear benefit and, in some cases, led to degradation, likely due to prolonged sonication and water immersion. Color values showed minimal undesirable changes with US pretreatment, and higher L* values (lightness) were retained in most cases. a* and b* values increased after drying processes. Principal component analysis (PCA) effectively differentiated treatment groups based on all measured parameters. US pretreated and unpretreated samples are positioned in the same place, while intermittent microwave dried and fresh samples are in a different plane. In conclusion, US pretreatment and microwave drying are promising technologies for improving drying efficiency and maintaining quality in dried apple products.

Kübra Arslan | Muhammed Raşit Durak | Hilal Özkılınç
Mitochondrial genomes are key targets in controlling fungal plant pathogens and mediate adaptive responses like fungicide resistance. Respiratory inhibitor fungicides (RIs) are widely used against many fungal pathogens, including Monilia fructi cola and M. lax, which are casual agents of brown rot of stone fruits worldwide. Although resistance to RIs has been reported in these species, the genetic basis is not fully elucidated. and is hypothesized to involve mitochondrial genome variations. To explore this, mitogenomic variations was comprehensively analysed to assess the resistance responses of two Monilia species to three RIs, including two technical grade fungicides (bosclid and azoxystrobin) and, a commercial one (signum). Whole mitogenome data from sixteen isolates of two species with different resistance/susceptibility phenotypes were analysed for certain gene mutations, mitochondrial variants, heteroplasmy, and sequence kernel associations. The results indicated that commonly known mutations and low levels of heteroplasmy do not fully explain resistance. In Monilinia fructicola, the presence of multiple variants appears to contribute to resistance, however, no variant patterns corresponded significantly with resistance phenotype in M. laxa. Providing a broad perspective, this study serves as a valuable model and supports the potential of mitogenome-focused RI resistance research. These insights contribute to a better understanding of specific resistance responses, thereby supporting the development of more effective pathogen control strategies.

Microgreens have become popular due to the positive health and high nutritional value effects of the bioactive compounds they contain. This study aimed to determine the total phenolic, flavonoid and antioxidant contents of red radish and parsley microgreens and to evaluate their anticancer effects in chronic lymphocytic leukemia cells (CLL). After methanolic extraction of microgreens, DPPH, radical scavenging activity and total polyphenol and flavonoid content were analyzed spectrophotometrically. The effects of microgreens on MEC-1 and HG-3 CLL cell lines were determined by MTT method. The methanolic total flavonoid content of red radish and parsley microgreens were 2,562 mg/g RE and 1,306 mg/g RE, respectively; total polyphenol contents were 4,133 mg/g GAE and 1,851 mg/g GAE, respectively; DPPH radical scavenging activity were 701,423 µg/g GAE and 625,717 µg/g GAE, respectively. The IC50 concentrations were found 70 mg/ml and 75 mg/ml for parsley microgreen for MEC-1 and HG-3 cell lines, respectively; 65 mg/ml for red radish microgreen for MEC-1 cells, while more cell proliferation was observed at the doses applied for HG-3 cells. Higher antioxidant content was found in microgreen radish than in parsley. Methanolic microgreen extracts significantly reduced cell proliferation in CLL cell cultures at varying levels. Of interest in terms of potential antitumor effects, microgreen radish extracts, which are rich in polyphenol content, showed a proliferative effect on wild-type CLL cells. In conclusion, this study is important in terms of revealing the activities of various microgreens, particularly radish and parsley microgreens, and detailing their benefits on human health.
