Orman ağaçlarında verimliliği artırmanın etkin yollarından biri de ıslah çalışmalarıdır. Islah çalışmaları ile ormanların büyüme hızını artırmak, biyotik ve abiyotik zararlılara karşı dirençli bireyler yetiştirmek mümkün olmaktadır. Bunun için genetik çeşitliliğinin belirlenmesi büyük önem arz etmektedir. Bu uygulamaların yapıldığı içerisinde tohum bahçeleri ayrı bir öneme sahiptir. nedenle yapılan araştırma Taşköprü Tekçam sarıçam klonal bahçesinde gerçekleştirilmiştir. Sarıçam türü hem ekonomik değeri olan ıslahının yapılması öngörülen tür olmasından dolayı tercih edilmiştir. Yapılan bu çalışmada 30 klonun 8 rametinden 3 tekerrürlü olarak toplam 240 adet ağaç rastgele örneklenmiştir. Ağaçların son yıl ibrelerinden örnekler alınarak laboratuvarda yıkama işlemine, ardından iki farklı kurutma işlemine tabi tutulmuştur. Daha sonra laboratuvara gönderilerek öncelikle eritiş yöntemi numuneler hazırlanmış, sonrasında ICP-OES cihazı Mg (Magnezyum) Mn (Mangan) element konsantrasyonları belirlenmiştir. Elde edilen veriler Minitab 18 paket programı yardımıyla varyans analizi Tukey testi değerlendirilerek klonlar arası içi çeşitlilik konsantrasyonlarına bağlı belirlenmeye çalışılmıştır. Çalışılan elementler bakımından arasında p

Variation of Gallium Concentrations in Some Forest Trees Depending on Species, Organ and Soil Depth

Published: Oct. 27, 2023

Heavy metal pollution is one of the most critical environmental problems threatening environment and human health. Therefore, studies on monitoring reducing heavy are among prioritized study topics. Plants effective tools to monitor reduce pollution. However, potential accumulation in various organs plants quite different. it necessary determine suitable species for this purpose have information transfer metals plant way entry into plant. In study, concentrations Gallium, dangerous health, were evaluated at different soil depths soils where Pinus nigra Arnold., sylvestris L., Fagus orientalis Libsky. Abies nordmanniana subsp. bornmülleriana Mattf. grow leaves, bark, wood, cones, root organs. As a result there was no statistically significant difference between terms mean values Gallium concentrations. contrast, highest importance basis obtained The lowest Regarding organs, wood roots.

Determination of 180-Year Variation of Li Concentration in the Atmosphere using Corylus colurna L. Annual Rings

Published: Oct. 27, 2023

Environmental pollution has increased significantly in the current century due to various anthropogenic effects, especially industrial activities, mining, urbanization, and traffic. Significantly increasing air become a global problem that causes millions of people die yearly. Heavy metals, most dangerous harmful components pollution, do not easily deteriorate disappear nature. They can be carried far from their source, tend bioaccumulate living organisms, some toxic, carcinogenic, fatal even at low concentrations for humans animals. Therefore, monitoring change heavy metal is critical. One effective methods determining concentration changes atmosphere past present using annual rings trees as biomonitors. In this study, variation Li concentrations, which one metals terms human environmental health, last 180 years, was tried determined by Corylus colurna L. tree rings, cut end 2020 Kastamonu province, Türkiye. Within scope, bark inner were also compared with woods, directional evaluated. As result, there significant difference between wood (p<0.05) except north direction element, obtained woods much higher than those bark. all directions, west direction, (p<0.05). However, generally varies narrow range, interpreted element being transferred C. colurna.

Variation of Aluminum Concentrations in Annual Rings of Some Trees Growing in Ankara City Center Depending on Years and Species

Published: Oct. 27, 2023

Heavy metal pollution is one of the most critical concerns threatening environmental and individual health worldwide in last century. metals air have particular importance due to their effects on human health. Therefore, watching difference heavy airborne extremely important. Tree annual rings are efficient biomonitors used define differences concentration levels during years. However, accumulation each element tree varies depending species. it necessary determine species that can be as separately determining over This study aimed variation Aluminum (Al) 30 years Ankara city center by using Platanus orientalis, Elaeagnus angustifolia L., Koelreuteria paniculata Laxm, Cedrus atlantica (Endl.) Manetti ex Carr. Ailanthus altissima (Mill.) Swingle trees. As a result, maximum aluminum concentrations were found outer bark all The orientalis L. wood part.
