Thuja Plicata Has Many Traditional Uses, from the Manufacture of Rope to Waterproof Hats, Nappies and Other Kinds of Clothing
photograph © Daniel Mosquin Culturally modified tree. The bark of Thuja plicata has many traditional uses, from the manufacture of rope to waterproof hats, nappies and other kinds of clothing. Careful, modest, bark stripping has little effect on the health or longevity of trees. (see pages 24 to 35) photograph © Douglas Justice 24 Tree of the Year : Thuja plicata Donn ex D. Don In this year’s Tree of the Year article DOUGLAS JUSTICE writes an account of the western red-cedar or giant arborvitae (tree of life), a species of conifers that, for centuries has been central to the lives of people of the Northwest Coast of America. “In a small clearing in the forest, a young woman is in labour. 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. Its cradle of firmly woven cedar root, with a mattress and covering of soft-shredded cedar bark, is ready. The young woman’s husband and his uncle are on the sea in a canoe carved from a single red-cedar log and are using paddles made from knot-free yellow cedar. When they reach the fishing ground that belongs to their family, the men set out a net of cedar bark twine weighted along one edge by stones lashed to it with strong, flexible cedar withes. Cedar wood floats support the net’s upper edge.

The evolution of seeds, pollen, and wood freed plants from the need for water during reproduction, allowed for more effective dispersal of sperm, increased parental investment in the next generation and allowed for greater size and strength. 2. Seed plants originated in the Devonian period from a group called the progymnosperms, which possessed wood and heterospory, but reproduced by releasing spores. Currently, five lineages of seed plants survive--the flowering plants plus four groups of gymnosperms: cycads, Ginkgo, conifers, and gnetophytes. Conifers are the best known and most economically important group, including pines, firs, spruces, hemlocks, redwoods, cedars, cypress, yews, and several Southern Hemisphere genera. 3. The pine life cycle is heterosporous. Pollen strobili are small and seasonal. Each sporophyll has two microsporangia, in which microspores are formed and divide into immature male gametophytes while still retained in the microsporangia. -

K* 1, J. Rathinamala 1 and S. Jayashree 2 1Department of Microbiology, Nehru Arts and Science College, Coimbatore, 2Department of Biotechnology, Nehru Arts and Science College, Coimbatore, Tamil Nadu, India. Received: 05 March 2014 ; Revised: 25 April 2014 ; Accepted: 03 May 2014 Abstract: Use of chemical fungicide to control plant diseases causes several adverse effects such as, development of resistance in the pathogen, residual toxicity, pollution to the environment etc. So an alternative way to overcome the usage of dreadful chemicals is very important. The use of plant extracts as biofungicide is one of the popular and effective method. Araucaria columnaris is a commonly seen ornamental plant known as Christmas tree. It’s a South African species, under the family Araucariaceae. Hence, in the present study, the plant resin extract was tested in-vitro against major plant pathogensby preliminary bioassay. It was found that up to 95% reduction of mycelium growth was observed against major phytopathogens such as Fusarium oxysporyum , Rhizoctonia sp, Cylindrocladium sp, Alternaria sp, and Colletrotricum sp., causing tomato wilt, damping off, foliage blight, and leaf blight diseases in economically important plants. Up to our knowledge it is the first report showing the antifungal activity of Araucaria columnaris resin as antifungal agent. -

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). -
