Growth responses of scots pine seedlings grown in peat-based media amended with natural zeolite
(Triveni Enterprises, 2006)Zeolite has many good features that makes it very attractive for nursery use as a growing media over others. This study was designed to investigate influence of different growing media and their mixtures (with zeolite and ... -
Non-wood forest products as a component of the total economic value of Turkish forests
(Academic Journals, 2006)Forests like other natural resources perform a set of functions to meet the needs of people. It is usually impossible to state the monetary value of all goods and services provided by forest resources in most countries. ... -
Preliminary results on the effects of various pre-treatments on seed germination of Juniperus oxycedrus L.
(International Seed Testing Association, 2007)Seeds of Juniperus oxycedrus L. have seed-coat and embryo dormancy hampering complete, rapid and uniform germination. Twenty treatments including stratification and scarification were conducted to overcome seed dormancy. ... -
Antioxidant potentials and rosmarinic acid levels of the methanolic extracts of Salvia verticillata (L.) subsp. verticillata and S. verticillata (L.) subsp. amasiaca (Freyn & Bornm.) Bornm
(Elsevier, 2007)This study was dcsigned to i:xanıine the in vitro antioxidant activities and rosmarinic acid levels of the methanol extracts of Salvia verticillata subsp. vertici/laıa and S. verticillata subsp. amasiaca . The extracts ... -
Effects of land-use regime on soil erodibility indices and soil properties in Unye, Turkey
(Parlar Scientific Publications, 2007)We evaluated the effects of land-use regime on soil erodibility indices and several soil properties in forested, deforested, and cultivated areas in the village of Unye, Turkey. Twelve sample plots (spaced 150 m apart) ... -

(Elsevier, 2007)This study was dcsigııed to examine the in vitro antioxidant activities of the essential oil and methanol extracts of Satııreja Jpicigera and S. cımeifo/ia from Turkish flora. GC and GC/MS analysis of the essential oils ... -
Mapping secondary forest succession with geographic information systems: a case study from Bulanikdere, Kırklareli, Turkey
(Tübitak, 2007)Developing forest management plans for sustaining the full range of forest values is a challenging task. One of the difficulties in this process is to set and achieve management objectives, and conservation targets. A ... -
Seed germination of three provenances of arbutus Andrachne L. in response to different pretreatments, temperature and light
(Sejani Publ, 2007)Seeds of Arbutus andrachne possess a physiological dormancy that prevents synchronized and rapid germina tion. The seeds were subjected to different pretreatments involving hot water, concentrated sulphuric acid, gibberellic ... -
Effects of gap-size classes on long-term litter decomposition rates of beech, oak and chestnut species at high elevations in northeast Turkey
(Springer, 2008)Effects of gap-size classes on litter decomposition rates were investigated in a high-elevation forest for 4 years by placing leaf litter of beech (Fagus orientalis Lipsky.), oak (Quercus robur L.), and chestnut (Castanea ... -
