Improvement of Forest Trees

Species Diversity of Trees and Forest Floor Plants in Oriental beech Forest Types of Shastkalate Educational and Research Forest, Gorgan)

Trees are the most important biological elements of forest ecosystems. The variability of the tree species composition inhabiting in the Oriental beech forest, not only forms different forest types but also has a remarkable impact on the species diversity of forest floor plants, due to the existence of trees in the overstory layer. In this research, forest types of an an Oriental beech were ide...

Genetic Improvement of Christmas Trees

While seed source selection is an important initial step in the genetic improvement of Christmas trees, continuously returning to seed collections from natural stands precludes any further improvement in genetic quality. In addition, the genetic variation within most seed sources is tremendous and varies from year to year. In order for the Christmas tree industry to move past the current level ...

Molecular and physiological responses to abiotic stress in forest trees and their relevance to tree improvement.

Abiotic stresses, such as drought, salinity and cold, are the major environmental stresses that adversely affect tree growth and, thus, forest productivity, and play a major role in determining the geographic distribution of tree species. Tree responses and tolerance to abiotic stress are complex biological processes that are best analyzed at a systems level using genetic, genomic, metabolomic ...

Population and conservation genomics of forest trees: seeing the forest for the trees

Background Forest trees exhibit striking adaptations to the environments in which they grow. A long history of quantitative genetic experimentation has established the genetic basis for many traits, which are likely adaptive since many of them are also correlated with environmental heterogeneity. The genes underlying these traits, however, have largely remained elusive. Recent applications of h...
