This study was carried out to determine the effects of some pretreatments including soaking in concentrate H2SO4, GA3, floating hot water and cold stratification their combinations on seed germination investigate how overcome dormancy seeds drought-tolerant plants. The species used this were Arbutus andrachne L., Cistus creticus Colutea armena Bois. Huet., Cotinus coggyria Scop., Cotoneaster numullaria Fisch.M for 1 minute both under greenhouse (66.89%) open field (44.89%) conditions, C....
The possibility of early testing coastal Douglas-fir (Pseudotsuga menziesii var. (Mirb.) Franco) for Swiss needle cast (SNC; caused by Phaeocryptopus gaeumannii (Rohde) Petrak) tolerance was investigated using 55 families from western Oregon. Seedlings were inoculated with P. naturally in the field and visually scored a variety SNC symptom traits (i.e., foliage color, retention) at seedling stage (age 2) "mature" (ages 10 12) trees two test sites both mature ages. also assessed laboratory...
ritanya Kolumbiyası (BC), Kanada’nın en batısında yer alan ve Türkiye yüzölçümünün yaklaşık 1,2 katı büyüklüğündeki bir eyaletidir. BC’nin yarıdan fazlası ormanlarla kaplıdır ormancılık, enerjiden sonra Eyalet ekonomisinin önemli ikinci sektörüdür. Neredeyse tamamı (%95) devlete ait olan bu ormanlardan her yıl 200 bin hektarı (ha) kesilmekte bunun %80’i yapay olarak gençleştirilmektedir. Yıllık fidan ihtiyacının %82’si Pseudotsuga menziesii, Pinus contorta var. latifolia Picea glauca x...
Abstract Wind-pollinated seeds from 40 trees (half-sib families) were collected each of six Turkish red pine (Pinus brutia Ten.) populations in southern Turkey. Two-year old seedlings evaluated for growth, phenology and cold resistance a common garden experiment established Ankara, located outside the species’ natural range. Each family was represented with six-tree row plot within three replications. The below freezing temperatures (-15.2°C) observed January February 2000 sufficient to...
Summary This study examined 108 15‐year‐old Douglas‐fir ( Pseudotsuga menziesii var. ) trees to investigate whether exhibiting less severe Swiss needle cast (SNC) symptoms were more resistant (had fungal colonization) or tolerant (maintained healthy foliage under similar infection levels). Trees sampled from six open pollinated families that categorized into three disease severity groups (two for each group; mild, moderate and symptoms). The amount of retained level discoloration visually...
Bu çalışmada Türkiye'deki 18 doğal Türk fındığı popülasyonunun konum ve iklim verileri irdelenmiştir. İncelenen popülasyonlar küçüktür (ortalama alan = 206 ha) deniz seviyesinden 700 ila 1600 m arasında bulunmaktadır. Popülasyon konumlarında yıllık ortalama sıcaklık 8.83°C (aralık: 6.9 − 11 °C) yağış 654.28 mm 477 952 mm) olarak belirlenmiştir. Türün kurak yarı-kurak alanların ağaçlandırılmasında kullanılması yönünde bir ilgi vardır ancak incelenen popülasyonların sadece üçü sahalarda Diğer...
Two 15-year-old Douglas-fir (Pseudotsuga menziesii var. (Mirb.) Franco) test plantations at Artvin, in the eastern Black Sea Coast Region of Turkey, were inspected July 2003. Trees both had yellow-to-brown foliage, and most trees retained only current year's needles, resulting sparse tree crowns. Numerous minute, black fruit bodies present along rows stomata on lower surfaces needles from plantations. Laboratory examination revealed that fruiting emerged through those Phaeocryptopus...
Effects of 10-year storage on germination seeds in 191 Anatolian Black Pine trees from 23 populations the Lakes Region Turkey were investigated. Germination tests conducted with both fresh (in year 1999) and stored 2009) variation was related to geographic features populations. Significant reductions rate (from 79.93% 30.68%) percentage 95.99% 58.41%) observed after storage. characteristics seem be associated humidity population locations. Seeds more inland (i.e., continental) germinated...
Bu çalışma, ağaç malzemede emprenye işleminin yüzey pürüzlülüğü ve yapışma direncine etkilerini belirlemek amacıyla yapılmıştır.Bu maksatla, dış ortam şartlarında yaygın kullanım alanı olan sarıçam (Pinus sylvestris Lipsky), Uludağ göknarı [Abies nordmanniana (Stev.)subsp.bornmüllerana (Mattf.)]ve sapsız meşe (Quercus petraea Liebl.)odunlarından hazırlanan deney örnekleri, Vacsol-Aqua ile edilerek Polivinilasetat (PVAc) Desmodur-VTKA (D-VTKA) tutkalları yapıştırılmıştır
Variation in drought resistance and its relationship with adaptive physiological traits forest trees are important choosing suitable seed sources for reforestation afforestation programs. A common garden experiment using 240 half-sib families originating from coastal inland populations of Turkish red pine (Pinus brutia) Turkey was set up three replicates. The aims were to determine variation damage, height growth, phenology among investigate the between damage (i.e. plant moisture stress...

Bu çalışmanın amacı Doğu Ladini (Picea orientalis)’nin kozalak ve tohum özelliklerindeki coğrafi farklılıkların belirlenmesi amaçlanmıştır. Materyal olarak Ladininin Artvin Posof (Ardahan)’daki doğal yayılış alanı içinde 33 noktadan 3 veya 5 anaçtan açık tozlaşma ürünü kozalaklar toplanmıştır. Kozalak özelliklerine ait karakterler (kozalak boyu, eni, elde edilen tohumların 1000 tane ağırlığı, boyu kanat uzunluğu) ölçülmüştür. Araştırma alanının coğrafik göre bu veriler değerlendirilmiştir....
Abstract A maritime pine ( Pinus pinaster Ait.) breeding program was initiated in Türkiye by selecting plus trees from plantations across the country. Quantifying genetic variation growth traits is essential for this program. Four-year old 140 open-pollinated families were assessed height (HT), root collar diameter (D) and number of shoots fourth growing season (S) three progeny test (Kefken, Gebze Çatalca) northwest Türkiye. Growth greater Kefken, followed Çatalca. Both individual tree (h i...
Forest tree populations deal with climate change either by increasing frequency of alleles contributing to adaptation new conditions through natural selection or migrating places where they can establish and survive. In order for mechanism work, changes in allele frequencies rate migration should be able keep up the climatic changes. For most forest populations, however, is faster than their genetic rates. One potential solution this problem human assisted species involves moving seed...
This study was carried out to determine the effects of some pretreatments including cold stratification (20, 40 and 60 days), soaking in running water (15 °C) for 10 days + 30 days, snipping off 2 mm at seed ends on germination how overcome dormancy Elaeagnus angustifolia L. seeds.
