Sawara cypress [Chamaecyparis pisifera (Siebold & Zucc.) Endl.] is originally from Japan. It was introduced to Europe in the latter half of 19th century (in England and Holland 1861, Poland 1864). The aim this study examine influence climatic conditions on tree-ring width among populations growing Poland. Additionally, other indicators determining growth-climate relationship for studied tre...

An advanced pretreatment method that combines steam treatment (ST) with wet disk milling (WDM) was evaluated using two different species of woods, viz., Hinoki cypress (softwood) and Eucalyptus (hardwood). Bioconversion of the pretreated products was performed using enzymatic saccharification via a commercial cellulase mixture and two types of fermentation processing, i.e., yeast-based simultan...

Abstract. Many monoterpenes have at least two different stereochemical forms, and many biosynthetic pathways are known to favor one product over the other(s). A rapid method was developed used in determination of (-/+)-enantiomeric distributions for ?-pinene, ?-pinene, camphene, limonene, ?-phellandrene as emitted by plant material from six conifer species. The species included pine Pseudotsuga...

Responses of bald cypress (Taxodium distichum) and pond cypress (Taxodium ascendens) saplings in photosynthesis and growth to long-term periodic submergence in situ in the hydro-fluctuation zone of the Three Gorges Dam Reservoir (TGDR) were studied. Water treatments of periodic deep submergence (DS) and moderate submergence (MS) in situ were imposed on 2-year-old bald cypress and pond cypress s...

In the screening of biologically active constituents from woody plants, the methanol extract of leaves of Chamaecyparis obtusa showed potent neurite outgrowth-promoting activity in neuronal PC12 cells. The ethyl acetate-soluble fraction of the methanol extract showed potent activity and was separated by means of various chromatographic methods to give the two new compounds 1 and 2, as well as 1...

Forest certification is slowly but steadily expanding in Japan, with the total area of certified forest being around 2.5 million ha or 10% all forestland. However, FSC (Forest Stewardship Council) PEFC (Programme for Endorsement Certification) products are still uncommon because few companies undertake CoC (Chain Custody) certification. We conducted experimental sales and non-certified cutting ...

WHIGHAM, D. F., and RICHARDSON, C. J. 1988. Soil and plant chemistry of an Atlantic white cedar wetland on the Inner Coastal Plain of Maryland. Can. J. Bot. 66: 568-576. Atlantic white cedar (Chamaecyparis thyoides (L.) BSP.) wetlands are widely distributed along the Atlantic coast, yet there is very little information on their nutrient dynamics. In this paper we present data on the chemical co...
