Morphological measurements of Anatolian chestnut (Castanea sativa Mill.) leaves were done within the borders Abana district Kastamonu province. The study was conducted using mixed (oak, beech, hornbeam, black pine, and yellow pine) medium (41% to 70%) fully closed (71% 100%) stands. Some leaf parameters, such as blade width, petiole length, distance between lateral veins, teeth angle base petiole, midrib measured. Moreover, stomata picked up from precise altitudes observed under a scanning electron microscope. differences fibre elevation, wall thickness, elasticity coefficient, rigidity Muhlstep rate, Runkel ratio found in wood samples taken different altitude zones. It that did not affect felting ratio, lumen width. However, it determined affected other studied characteristics.

Seed orchards with high hereditary qualities and the improvement studies used are of great importance. This study was carried out on individuals in a Boyabat grafted black pine seed orchard, Sinop. The morphological micromorphological measurements characteristics were performed needle samples taken from individuals, genetic diversity determined clonal basis. According to analysis variance applied data obtained characters clones, it that there significant difference among clones at P<0.001 confidence level. In this context, according Duncan’s Range test, creation large number groups is an indicator it. highest heritability rates diameter, stipule dorsal stoma, length characteristics.

Variation Of Ge Concentration In Some Coniferous Species Over Long Years

Menba Kastamonu Üniversitesi Su Ürünleri Fakültesi Dergisi, Journal Year: 2025, Volume and Issue: 11(1), P. 24 - 33

Published: March 28, 2025

: Increasing natural events and human activities in the last century led to release of an excessive amount inorganic organic pollutants into environment ecosystems. One most important disrupting balance between living organisms ecosystem is metals. Heavy metals, particular, are transported top levels food chain cause harm organisms. Therefore, among pollutants, heavy metals have a specific ecological importance. carcinogenic and, due their bioaccumulative, non-degradable, refractory characteristics, they pose serious health risks systems environment. Pinus pinaster (Pp), Cupressus arizonica (Cpa), Picea orientalis (Po), Cedrus atlantica (Cda) Pseudotsuga menziesii (Pm) species were examined present study. Changes Ge concentrations these by directions organs periods 1988-1992 2013-2017 determined. As result study, lowest concentration was found west Pb (872.8) highest one north Cpa (6367.5). The study revealed that accumulation plant analyzed here at considerably high level. These results suggest pollution air very high.

Eight-year-old Abies fraseri seedlings were grown under different irrigation regimes to determine how drought stress might affect the in terms of gas exchange parameters. In this study, net photosynthesis (Anet), transpiration rate (E), stomatal conductance (gs), intercellular CO2 (Ci), Ci ambient (Ca) concentration ratio (Ci/Ca), intrinsic water use efficiency (iWUE), and (WUE) measured on August 11 27. Irrigation measurement time statistically significant all parameters except WUE for Anet time. E gs interactions. increasing generally decreased Anet, gs, while increased E, iWUE, Ci/Ca. On 27, A. had higher Ci, Ci/Ca, lower iWUE values than 11. However, there was a robust positive correlation between negative seedlings. general, prolonged deficiency leads plants decrease increases, contrary current study. A well-developed deeper root system, especially less or no-irrigation regimes, may alleviate effects long run provide an advantage leaf addition, fact that soil moisture did not differ much treatments, although levels different, explain similar behavior among individuals

Abstract Airborne metals and organic pollutants are linked to severe human health impacts, i.e. affecting the nervous system being associated with cancer. polycyclic aromatic hydrocarbons (PAHs) in urban environments derived from diverse sources, including combustion industrial vehicular emissions, posing a threat air quality subsequently health. A lichen biomonitoring approach was used assess spatial variability of airborne PAHs, identify potential pollution sources risks across City Manchester (UK). Metal concentrations recorded samples were highest within city centre area along major road network, PAH profiles dominated by 4-ring PAHs (189.82 ng g −1 Xanthoria parietina ), 5- 6-ring also contributing overall profile. Cluster analysis index factor (PIF) calculations for lichen-derived metal suggested deteriorated primarily emissions. Comparably, diagnostic ratios identified as primary cause Manchester. However, local more complex (e.g. emissions) further identified. Human risk assessment found “moderate” adults children harmful element (PHEs) concentrations, whereas exposure is potentially 1455 (ILCR = 1.45 × 10 −3 ) cancer cases (in 1,000,000). Findings this study indicate that an easy-to-use can aid hotspots impaired impacts environment, particularly at locations not continuously covered (non-)automated measurement programmes. Graphical

Background: Heavy metal contamination in the air has been gaining importance from scientists due to increasing industrial activities, population growth, and density urban areas causing many crucial environmental pollution problems. metals do not quickly disappear decay nature; they accumulate plant organs indirectly affect human health. On other hand, some elements are essential for but have poisonous or carcinogenic consequences, even at small concentrations. Thus, determining observing heavy concentrations atmosphere is crucial., Plants utmost important indicator of concentration changes called biomonitors. The current study aims determine variation (K, P, Fe, Zn, Cu, Cd, Cr) inPicea pungensEngelm. (valued its bluish silvery-gray foliage) grown Ankara city center (capital Türkiye second crowded city), based on needles age branch. this tried potential using needle leaves branches ofP. pungens as a biomonitor Results: significantly differed by organ age. element levels were higher years years. Conclusions: This result indicates that Picea suitable studied Using does also harm species.
