Despite recent advances in our understanding of drought impacts on tree functioning, we lack knowledge about the dynamic responses of mature trees to recurrent drought stress. At a subalpine forest si...
Climate change has significant effects on forest ecosystems around the world. Since tree diameter increment determines forest volume increment and ultimately forest production, an accurate estimate of...
Vegetation indices (VIs) are mainly associated with plant yield, and yield-related physiological traits can assist in breeding selection. Tree breeding programs require a rapid assessment of a large n...
A forest's ability to store carbon depends on the bedrock beneath, according to Penn State researchers who studied forest productivity and composition and the physical characteristics of roc...
Manual in-situ measurements of geometric tree parameters for the biomass volume estimation are time-consuming and economically non-effective. Photogrammetric techniques can be deployed in order to aut...
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...
Coppicing was widespread throughout Europe for many centuries but was largely abandoned in the second half of the 19th century. Currently, there has been a renewed interest in coppicing for biomass ...
From 2008 to 2013 the phenology, early tree growth, precocity, yield, fruit quality attributes and leaf nutrient status of four sweet cherry cultivars (May Early, Germersdorfer, Sunburst and Celeste) ...
The spruce-fir-beech dominated forest stands in Litschau in the Austrian part of the Bohemian Massif were converted by former forest management practices into pure Norway spruce stands and are now dis...
Several characteristics related to tree growth, their fruitage and resistance against scab and powdery mildew were assessed during 2007–2008 on fi ve new cultivars in comparison with the ancestr...
The phenological stages, flower characteristics, shoot growth and flower bud differentiation of sweet cherries, cv. Hongdeng and Van, were investigated in different climatic zones in China, subtropica...
Coppicing was widespread throughout Europe for many centuries but was largely abandoned in the second half of the 19th century. Currently, there has been a renewed interest in coppicing for biomass pr...
Functional-structural models provide detailed representations of tree growth and their application to forestry seems full of prospects. However, owing to the complexity of tree architecture, parametr...
The Boom en Beeld project aims at developing a methodology for change detection of tree objects in urbanareas using imagery. This paper focuses on one aspect of this methodology, the prediction of the...
We evaluated the effects of training and culture methods on tree growth, yield and dry matter production in the Japanese pear ‘Kousui’. We adopted two culture methods: conventional culture and rhizosp...
