متن کاملDifferences in Genetic Structure among Fagus orientalis Lipsky (Oriental Beech) Populations under Different Management Conditions: Implications for in situ Gene Conservation
Resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. To observe how differences in forest management affect the genetic structure of Fagus orientalis Lipsky (oriental beech), we evaluated thirteen beech sites across Hyrcanian forests, based on six microsatellite loci. Significant di...
متن کاملSynthesis Report: Forest Genetic Resources in the EU
Conservation of forest genetic resources has always been an integral part of tree improvement programs. However threats to FGR, such as habitat destruction, fragmentation, pollution, the use of low quality forest reproductive material and climate change have increased in the past decades and with it the need to maintain FGR. During the past two decades several policy instruments and initiatives...
متن کاملEffects of converting forest to the rainfed lands on soil characteristics in a part of Zagros forests
The forest soils are the key parts of the Earth system that are globally degraded through anthrop induced deforestation, mainly converting to other landuses. The present study was conducted in Gazafolya village located in Merek watershed, Kermanshah, Iran, in which the soil quality of the forest and converted forest (rainfed lands) with the same topographic and geologic conditions were compared...
متن کاملGenetic variability and relationship of pod and seed traits in Pongamia Pinnata (L.) Pierre., a potential agroforestry tree
Screening of twenty-four candidate plus trees from naturally available Pongamia pinnata genetic resources was carried out to elucidate the genetic variation and relationship of pod and seed traits on germination capacity to select the best planting material for higher productivity. The experiment conducted at Forest Research Centre, Institute of Forest Productivity Mandar, Ranchi during 2005-20...
متن کاملComparison of Carbon and Nitrogen Sequestration in Soils Under Plantations, Natural Forest and Agricultural Farm Land Uses in Arjan Plain in the Fars Province
The carbon sequestaration by plants and soil is one of the easiest and the most econimical ways to reduce atmosphere carbon. This study was conducted on the planted land use of Fraxinus rotundifolia, Cupressus arizonica, obinia pseudoacacia L., Elaeagnus angustifolia, Cedrus libani, and Quercus brantii (persica) in the Arjan plain of Fars province. For each plantation land use, there were three...
