Two women companions urge her to pull hard on the cedar bark rope tied to a nearby tree. The baby, born onto a newly made cedar bark mat, cries its arrival into the Northwest Coast world.

Department of forfs't Sci e rt c*5 The University of British Columbia Vancouver, Canada Date April H , 2^003 DE-6 (2/88) Abstract Long-lived woody plants usually show high levels of outcrossing, inbreeding depression and genetic diversity compared to other plants. A review of the literature showed a mean oucrossing rate of 83.5 in conifers, and a positive, but weak, correlation between outcrossing and genetic diversity. Among conifers, western redcedar (Thuja plicata, Cupressaceae) has one of the highest rates of self-fertilization and lowest amount of genetic diversity, and thus offers the opportunity to study the evolution of inbreeding in a predominantly outcrossing group of plants.

  • Case Study of Anatomy, Physical and Mechanical Properties of the Sapwood and Heartwood of Random Tree Platycladus Orientalis (L.) Franco from South-Eastern Poland
    Article Case Study of Anatomy, Physical and Mechanical Properties of the Sapwood and Heartwood of Random Tree Platycladus orientalis (L.) Franco from South-Eastern Poland Agnieszka Laskowska * , Karolina Majewska, Paweł Kozakiewicz , Mariusz Mami ´nskiand Grzegorz Bryk The Institute of Wood Sciences and Furniture, 159 Nowoursynowska St., 02-776 Warsaw, Poland; [email protected] (K.M.); [email protected] (P.K.); [email protected] (M.M.); [email protected] (G.B.) * Correspondence: [email protected] Abstract: Oriental arborvitae is not fully characterized in terms of its microscopic structure or physical or mechanical properties. Moreover, there is a lot of contradictory information in the literature about oriental arborvitae, especially in terms of microscopic structure. Therefore, the sapwood (S) and heartwood (H) of Platycladus orientalis (L.) Franco from Central Europe were subjected to examinations. The presence of helical thickenings was found in earlywood tracheids (E). Latewood tracheids (L) were characterized by a similar thickness of radial and tangential walls and a similar diameter in the tangential direction in the sapwood and heartwood zones. In the case of earlywood tracheids, such a similarity was found only in the thickness of the tangential walls. The volume swelling (VS) of sapwood and heartwood after reaching maximum moisture content (MMC) was 12.8% (±0.5%) and 11.2% (±0.5%), respectively. The average velocity of ultrasonic Citation: Laskowska, A.; Majewska, waves along the fibers (υ) for a frequency of 40 kHz was about 6% lower in the heartwood zone K.; Kozakiewicz, P.; Mami´nski,M.; than in the sapwood zone.

  • Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
    1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus).

  • Chamaecyparis Lawsoniana in Europe: Distribution, Habitat, Usage and Threats
    Chamaecyparis lawsoniana Chamaecyparis lawsoniana in Europe: distribution, habitat, usage and threats T. Houston Durrant, G. Caudullo The conifer Lawson cypress (Chamaecyparis lawsoniana (A. Murray) Parl.) is native to a small area in North America. Variable in form, there are over 200 cultivars selected for horticultural purposes. It has been planted in many countries in Europe, usually as an ornamental, although the timber is also of good quality. It has been severely affected in its native range by root rot disease, and this has now spread to the European population. Chamaecyparis lawsoniana (A. Murray) Parl., known as Lawson cypress, or Port Orford cedar in the United States, is a Frequency large conifer native to North America. It belongs to the family < 25% 25% - 50% Cupressaceae, and is sometimes referred to as a “false-cypress” 50% - 75% to distinguish it from other cypresses in the family. It is long- > 75% lived (more than 600 years) and can reach heights of up to 50 m (exceptionally up to 70 m in its native range) and a diameter exceeding 2 m1, 2. The tree is narrowly columnar with slender, down-curving branches; frequently with forked stems. The bark is silvery-brown, becoming furrowed and very thick with age giving mature trees good fire resistance2, 3. The wood is highly aromatic with a distinctive ginger-like odour, as is the foliage which has a parsley-like scent when crushed3, 4. The evergreen scale-like leaves are around 2-3 mm long5. Abundant, round pea-sized cones ripen in autumn with seed dispersal occurring immediately after and continuing until the following spring6.

The total solvent extract solutions were analyzed as the free and derivatized products by gas chromatography-mass spectrometry to identify the compounds, which comprised minor mono- and sesquiterpenoids, and dominant di- and triterpenoids, plus aliphatic lipids (e.g., n-nonacosan-10-ol). Ferruginol, 7α-p- cymenylferruginol, and chamaecydin were the major characteristic markers for the Taxodioideae conifer subfamily. The mass spectrometric data can aid polar compound elucidation in environmental, geological, archeological, forensic and pharmaceutical studies.
