The extensive mortality of yellow-cedar along more than 1000 kilometers of the northern Pacific coast of North America serves as a leading example of climate effects on a forest tree species. In this article, we document our approaches to resolving the causes of tree death, which we explain as a cascade of interacting topographic, forest-structure, and microclimate factors that act on a unique ...
The relevance of studying the growth and development North American cypress tree species in Omsk region is due to short period their use urban landscaping. issues effective production planting material these rocks West Siberian have not been fully studied. landscaping city will expand range conifers reduce anthropogenic load. research devoted study effect stimulants on vegetative reproduction b...
Abstract The thermal reactivities of cellulose and hemicellulose are significantly different in cell walls when compared with isolated components differ Japanese cedar (softwood) beech (hardwood). Uronic acid bound to xylan promotes the degradation hemicellulose, its effect is depending on form free (acting as an catalyst) or metal uronate a base catalyst). We evaluated location uronic wall by ...
Vegetation analysis in ten central Florida cypress (Taxodium distichurn) swamps was undertaken to determ•ne the response of woody species composition to clearcutting. Line transects hrough swamps that had been harvested by clearcutting within the last 5 years demonstrated that all but one of these swamps are likely to recover their original species composition and a normal stem density. Cypress...
The conjugate gradient method is a powerful algorithm to solve well-structured sparse linear systems that arise from partial diierential equations. We consider here three diierent conjugate gradient schemes for solving elliptic partial diierential equations that arise from 5-point diierence schemes: the classical CG, CG with a block diagonal-block incomplete Cholesky preconditioner and the redu...
To identify genetic diversity, genetic structure and the relationship among accessions, and further establish a core collection for the long-term breeding of cypress (Cupressus funebris Endl.), the genealogy of breeding parents was reconstructed using simple sequence repeat (SSR) molecular markers. Seventeen SSR markers were used to detect molecular polymorphisms among 290 cypress accessions fr...
Turkey has 75% of the total number of plant species found in Europe. It is this exceptional amount of biodiversity that places a huge responsibility on Turkey, to ensure that these species are adequately protected in order to prevent them from being endangered or becoming extinct. Of particular importance are species related to the crops on which much of world agriculture depends. Many of the f...
The cypress family (Cupressaceae) possesses highly rearranged plastomes that lack a pair of large inverted repeats typically found in land plants. A few cypress species have been reported to contain isomeric plastomes, but whether the existence of isomeric plastomes is ubiquitous in the family remains to be investigated with a broader taxon sampling. In this study, we sequenced the complete pla...
