Cedar trees

The wood of Cryptomeria japonica, a Japanese cedar tree, yields an oil which contains a sesquiterpene to which the name suginene has been assigned. It has the following characters —... 

Cedar-apple rust completes its life cycle only where the fungal spores can travel back and forth between cedar and apple trees. Spores from cedar trees send spores to infect apple trees, but infections on the apple tree do not spread within the tree they can only send the disease back to infect cedar. 

At a site in Texas where a Phytokinetics, Inc., technology has been proposed, projected costs are 390,000. Groundwater at the 22-acre site is contaminated with salts and heavy metals. Cleanup would involve planting eucalyptus and salt cedar trees. Projected costs include expenses associated with greenhouse studies, field trials, and a full-scale application (D22474I, p. D-5). 

Two standard combustible materials may be used in this test. One is cellulose C, manufactured by The TOYO Filtratio Paper Co., Ltd. of particle size under 300 mesh and apparent specific gravity of 0.28 g/cm 3. The second is sawdust of 9-20 mesh in particle size with an apparennt specific gravity of 0.099 - 0.124 g/cm 1 and crushed wood for pets, made under the tradename "Woodshavings" by Japan Kurea. The sawdust is made from boiled fish paste and the board from American cedar trees. The reference sample is a fine sawdust for explosives with a particle size of 32- 50 mesh and apparent specific gravity of 0.175g/cm manufactured by Sanshin Industy Co., Ltd. 

One step in the synthesis of occidentaioi, a naturai product isoiated from the eastern white cedar tree, involved the foiiowing reaction, identify the structure of A and show how A is converted to B. 

Symptoms Hard, brown swellings appear on branch tips. These galls do not seriously damage cedar trees, but they can mar the plants appearance. Warm, moist weather in spring causes these galls to swell dramatically, and they produce gelatinous horns that release rust-colored spores. The spores then infect apple trees. For more details about this disease on apples, see Cedar-Apple Rust on page 373. 

However, since the early 1980s, growing numbers of mycophiles in North America and Europe have successfully used "natural outdoor cultivation" to fruit Psilocybe cyanescens and similar species. This process involves selection of natural wood substrates striated with mycelia (rhizomorphs) that usually turn blue in response to handling. The mycelia are then transferred onto fresh wood chips or commercial mulch (not from cedar trees). After several months of growth, the mycelia fruit during the fall season. 

Evergreen trees, weeds, drug-yielding plants, poisonous plants and rejuvenating plants. Mosses, Marshes, Cedar Trees, Palm Trees. 

Young leafy twigs used against some types of cancer. Commonly removes warts. Known as an abortifacient. Also called eastern arborvitae, eastern white cedar, northern white cedar, swamp cedar, tree of life. 

The impacts of acidification reach well beyond the direct toxic effects of high hydrogen ion concentration on plants and animals. Decline in the quality and growth rates of forests due to acid rain is well documented in several regions of the world" [44]. For instance, in the Sichuan province (particularly in Omei Mountain) of China, 87% of the cedar trees are seriously affected by acidification. Scandinavian scientists in 1960s first observed reduction of fish in lakes affected by acidification. Even a moderate acidification (pH 6.0) of surface waters can kill crustacean species. At pH < 5.5 loss of economically important fish species such as salmon and trout is expected. Hardy species such as the... 

The incense cedar tree, native to California and Oregon, is used for the manufacture of pencils, fence posts, boarding, Venetian blinds, chests and toys. Cases of contact dermatitis have been described by Calnan (1972). Positive reactions were obtained with thymo-quinone (3-thujaplicin remained negative. Incense cedar contains up to 4% of thymoquinone (for structure, see Thuja plicata). 

The western red cedar tree is native to the west coast of the United States, but exported all over the world, especially to Australia, Japan and Europe. It is a timber of good stability useful for constructions, Venetian blinds, boat building, planking, panelling and framing. Besides many cases of bronchial asthma due to the... 

Isolongifolene-9-one (442), which was isolated from some cedar trees, was treated in G. cingulata for 15 days to afford two primary alcohols (443, 444) and a secondary alcohol (445) (Sakata and Miyazawa, 2006) (Figure 20.126). 

On the other hand, the number of publications regarding the determination of the two natural moss extracts restricted as potentially allergenic - treemoss and oakmoss - is rather scarce. The industrial processing varies considerably, but basically, harvested lichens, from oak trees in the case of oakmoss and pine and cedar trees in the case of treemoss, are extracted, usually with hexane or more polar solvents. Then, they are further diluted in ethanol and usually submitted to physical treatments intended to remove their original color. Taking into account their natural conditions and that industrial processing is not standardized, it is not surprising to find variability in the chemical composition of these extracts. Joulain et al. published two comprehensive reviews on the composition of these extracts. One hundred seventy cmistituents are identified in oakmoss extracts and 90 in the case of treemoss [42,43]. 

For the preparation of lacquer ware, the oriental lacquer is usually applied on cedar wood, particularly from the Japanese cedar tree because it is the most warp resistant wood. One coat or two coats of primer, unprocessed urushi sap is applied followed by subsequent very thin layers (from twenty to forty layers) of processed "raw urushi" lacquer, one layer at the time every one or two days per application and curing. High relative humidity at the time of application and during curing is very critical it must be in the range from 65 to about 80%. ...
