Tomato leaf miner is an aggressive and invasive pest that causes serious damage in tomato production, resulting in up to 100% yield losses during serious outbreaks. The management of tomato leaf miner with synthetic pesticides is difficult due to its leaf mining habit, short life span, high reproductive rates, and insecticide resistance problem. In this study, sequences of the mitochondrial cytochrome oxidase I (mtCOI) gene of Tuta absoluta specimens were analyzed and compared with the available COI sequence data members from GenBank. All the specimens of tomato leaf miner were clustered together in a single group with a high support …

Turkish Journal of Agriculture and Forestry
Herein, the effects of roasting levels (rare, medium, and well) on the fatty acid composition, oil and polycyclic aromatic hydrocarbon (PAH) contents of various dried nuts (almonds, hazelnuts, peanuts, and cashews) were investigated. The roasting level affected the moisture and total oil contents, as well as the fatty acid composition. The roasting level had no significant effect (P > 0.05) on saturated fatty acid (SFA), monounsaturated fatty acid (MUFA) contents of the dried nuts, while it had a significant effect (P < 0.05) on polyunsaturated fatty acid (PUFA). In raw and dry roasted nut, the most common SFA, MUFA, and PUFA were palmitic, oleic, and linoleic acid, respectively. The amounts of linoleic acid and ΣPUFA, as well as ΣPUFA/ΣSFA ratio were the lowest in the well roasted samples. Additionally, the types of dried nut had a significant effect (P < 0.01) on the amounts of total oil and fatty acid compositions. The highest total oil amount (62.15%) was found in hazelnuts, while the lowest PUFA content (7.54%) was also determined in hazelnuts. From the nutritional perspective of view, the highest ΣPUFA / ΣSFA ratio (2.40) belonged to almonds. Although the recovery rates of PAH standards varied between 70.14%-85.10%, none of the heavy PAH compounds could be detected in raw and roasted samples.

Cotton is an essential fiber producing crop in the world. It also supports additional industries by providing high quality oil and protein in the form of cottonseed cake. Currently, there is an urgent need to increase lint yield, fiber quality, and resistance to biotic and abiotic stresses due to rising pressure from a global population and possible supply shortages from the effects of erratic climate changes. Classic plant breeding and transgenic strategies need more genetic breakthroughs to support the increasing pressure for fiber quantity and quality. A potential for rapid increases in crop improvement is in various state-of-the-art gene editing …

Choosing appropriate designs and methods for monitoring crop growth is a challenging process of major importance. Remote sensing from space and manned or unmanned airborne operations are used to measure crop reflectance and a wide variety of other agricultural parameters. While some experiments use only a few, specific methods and designs and organize the results in lists of evidence, other experiments use a wider range of techniques to create a more credible and comprehensive assessment of crop yield. Particular situations related to the available resources in terms of data collection and expertise in addition to the intended use of the …

The cement dust deposition can cause environmental pollution and heavy metal contamination, which negatively impacts soil nutrient availability and hence crop productivity. Thus, this study evaluates the impact of cement dust emissions on soil elemental compositions in different tillage managements. In this study, composite soil samples were taken from conventional tillage (CT), and notill (NT) managed fields under wheat-sugar beet (potato)-fallow cropping sequence. Soil samples were randomly collected from 0-30 cm depth in three replications and different distances (1, 2, 4, 6, 8, and 10 km) from a cement plant.

The use of microsatellite (SSR) markers has successfully found its application in genetic characterization and examination of the origin of a large number of fruit species. Mediterranean germplasm is characterized by a great variety of almond genotypes. The study covered two geographically distant regions Montenegro (Bar) and Croatia (Sibenik) in a sample of 60 almond genotypes. Genetic analysis of almonds involved the use of ten microsatellite primers for genetic characterization of 60 examined genotypes, which successfully amplified PCR products and were highly polymorphic. Nine microsatellite markers used for the genetic characterization of almonds are derived from Prunus persica (UDP97-402, UDP98-411, …

Turkish Journal of Agriculture and Forestry
The results of morphological and AFLP variability of 120 plants of carob tree (Ceratonia siliqua L.), collected from 12 different locations (10 biological replicates for each location) on the coast and islands of the southern Croatian Adriatic, indicate high molecular and morphological variability among these carob populations. Analysis of molecular variance revealed significant differences among populations (26.07%; p < 0.001; a = 0.05). Out of the total variability, 22.49% refers to the variability among, and 77.51% within populations. UPGMA and STRUCTURE analysis based on AFLP genetic data clustered carob populations into three main groups representing three real genetic populations. UPGMA analysis based on morphological traits of leaves, pods, and seeds clustered carob populations into five groups. Mantel test showed significant correlation between morphological and genetic data (r = 0.58, p < 0.001; a = 0.05). According to the high genetic and morphological variability, the germplasm collection in the analysis could represent an important genetic pool for future breeding programmes. The goal of future research should be the conservation of C. siliqua in its natural habitats, and the establishment of gene banks of genetic resources with the purpose of creating new carob cultivars in breeding programmes.

Maintaining and managing trees with different ecological plasticity under climate conditions aggravated by short-term variability are major challenges for foresters. Our aims were to investigate species-specific ecophysiological responses of canopy trees in a mixed Turkey oak forest during their early-phase regeneration. We measured plant carbon and water exchange with portable IRGA equipment under natural field conditions (canopy gap) and in a climate-controlled (standardized) environment. We analyzed variability and differences in plant gas exchange in relation to important abiotic site parameters and the species. Assimilation, stomatal conductance, and intrinsic water use were applied as calibrating parameters for plant functional fingerprinting to …
