A parsimonious and compatible system of taper, total, and merchantable volume equations sharing a common vector of three parameter estimates was derived from Clark and Saucier’s (1990) volume ratio model. Clark and Saucier’s model expresses volume inside bark as a function of outside bark diameter and is itself not compatible with the derived taper equation. To ensure compatibility, models were...

The study was carried out to investigate the antimicrobial, antioxidant potential and the qualitative and quantitative phytochemical analysis of the bark and leaf of Cocculus laurifolius DC. by using polar and non-polar solvents, i.e. Petroleum ether, Chloroform, Methanol and distilled water. Chloroform bark extracts showed maximum % yield. Antimicrobial activity was determined by using 4 bacte...

in recent years, shallow bark canker of walnut (juglandis regia l.) trees has become fairly widespread in iran. to determine the distribution of the disease in golestan, mazandaran and gilan provinces, from early summer to mid-fall seasons of 2004, more than one hundred bark samples were collected from walnut trees showing symptoms of shallow bark canker. sixty strains of bacteria were isolated...

Quillaia extracts (synonyms: quillaja extracts, bois de Panama, Panama bark extracts, quillai extracts, Quillay bark extracts, soapbark extracts; C.A.S. no. 68990-67-0, INS no. 999) are obtained by aqueous extraction of the milled inner bark or whole wood of Quillaja saponaria Molina (family Rosaceae), which is a large evergreen with shiny, leathery leaves and a thick bark, native to China and ...

Efforts to restore longleaf pine across the southeast United States have occurred on two distinct site types: cutover forests and old agricultural fields. We measured wood bark physical properties of unthinned planted from 16 stands Georgia, ages 12 25, with eight sampled each type. Three-hundred twenty trees were felled 3572 disks collected within trees. Wood specific gravity (SG), moisture co...

Background and Purpose: Oral candidiasis is one of the most common fungal infections in humans. The treatment and prophylaxis of the patients suffering from this infection require the identification of new anti-Candida agents with no side effects or toxicity like medicinal plants. The present study was conducted to compare the antifungal activities of the aqueous, ethanolic, and methanolic extr...

The leguminous tree Sophora japonica contains a family of closely related, but distinct, lectins. Different members of this family are independently expressed in seeds, leaves, and bark (CN Hankins, J Kindinger, LM Shannon 1987 Plant Physiol 83: 825-829; 1988 Plant Physiol 86: 67-10). The inter-, and intracellular distribution of the bark and leaf lectins was studied by indirect postembedding i...
