Climate Effects on Black Spruce and Trembling Aspen Productivity in Natural Origin Mixed Stands
dynamic models height growth functions mixed effects models biotic and edaphic effects climate change site productivity
2023/12/6
Forest managers need site productivity estimates for tree species growing in mixed stands. Models developed in the past are generally for pure stands and don’t factor in the effects of climate change ...
Spatial and temporal regulation of parent-of-origin allelic expression in the endosperm
programmed cell-death seed development DNA methylation gene-expression intact method arabidopsis embryo plants life identification
2023/11/16
Genomic imprinting promotes differential expression of parental alleles in the endosperm of flowering plants and is regulated by epigenetic modification such as DNA methylation and histone tail modifi...
Effects of seed origin, growing medium and mini-plug density on early growth and quality of black locust (Robinia pseudoacacia [L.]) seedlings

Origin and Regional Differences Density of Douglas Fir [Pseudotsuga menziesii (Mirb.) Franco] Wood
2009/1/16
In this study, the effects of origin and regional differences on the density of Douglas Fir [Pseudotsuga menziesii (Mirb.) Franco] wood were investigated. A total of 18 trees of 23 different ages obta...
Effects of Seed Origin and Site on Wood Density of Sitka Spruce（Picea sitchensis（Bong.）Carr.）Grown in Britain
Seed Origin Site Wood Density Sitka Spruce Plantations
2009/1/13
Since density may have a direct influence on wood properties and because density is a factor under genetic control, this study details the effects of seed origins and sites on density. In addition to...
