Individual tree-based growth models precisely describe the growth of individual trees irrespective of stand complexity. These models are more useful than the stand-based growth models for effective ma...
In temperate climatic conditions, plantations of poplar and willow species provide sustainable production of biomass. Short rotation coppice plantations on agricultural lands have a great potential to...
We measured the initial growth performance of a young plantation of European beech treated with a brassinosteroid compound prior to planting and compared it with a control treatment: we assessed heigh...
Adaptation variability and ecological plasticity in the “genotype-environment” system of 22 provenances of Picea abies (Linnaeus) H. Karsten, Picea obovata (von Ledebour) and their introgressive hybr...
This study concerns some of the relevant topics of the Iranian Caspian forestry planning problem, in particular the first central components in this modelling process, such as forest modelling, fores...
The area of forest destruction as well as the annual growth loss due to road construction before constructing a road was predicted. To do this, road cross sections of 88 points along the 10 km propose...
In this paper, the effect of the Bio-Algeen® product (bio-alginate from the seaweed Ascophyllum nodosum (Linnaeus) Le Jolis) was evaluated in relation to basic mycorrhizal and growth characterist...
A legacy of acid rain has acidified forest soils throughout the northeastern US, lowering the growth rate of trees. In an attempt to mitigate this trend, in 1999 scientists added calcium to an experim...
Four clonal progenies of wild cherry obtained using an in vitro technique and control progeny of generative origin were tested on the Polná research plot in southeastern Bohemia. Growth characteristic...
The study deals with differences in the growth of 2-year mix of poplar clones MAX 4, MAX 5 in the first rotation period at a site with the average moisture regime and at a neighbouring site affected b...
The possibility of reduce the length of poppy plants and their risk of lodging by applying selected plant growth regulators and effects on the plant and yield were studied in field experiments during ...
As money-makers, trees stand tall. The U.S. forest industry is an economic powerhouse. Southern states alone grow more commercial wood than any country in the world.The Center for Advanced Forestry Sy...
Foresters frequently lack sufficient information about thinning intensity effects to optimize semi-natural forest management and their effects and interaction with climate are still poorly understood....
