Radial increment in European spruce (Picea abies) as indicator of sanitary condition of spruce forests in the Ukrainian Carpathians

open access: yesBiosystems Diversity, 2020
In recent years, there has been an intense desiccation of spruce forests in the Ukrainian Carpathians, where European spruce is the main forest-forming species.

Dendroclimotological research of scots pine in stand of the Left-bank Forest-steppe of Ukraine

open access: yesЛюдина і довкілля: Проблеми неоекології, 2017
Purpose of this research was to detect influence of climatic change on pine radial increment in stand in the Left-bank Forest-steppe of Ukraine as example 100-years-old stand at State Enterprise 'Kharkiv forest scientific research station’.

Radial Growth of Qilian Juniper on the Northeast Tibetan Plateau and Potential Climate Associations [PDF]

open access: yes, 2013
There is controversy regarding the limiting climatic factor for tree radial growth at the alpine treeline on the northeastern Tibetan Plateau. In this study, we collected 594 increment cores from 331 trees, grouped within four altitude belts spanning the

A fast screening approach for genetic tolerance to air pollution in Scots pine field tests

open access: yesiForest - Biogeosciences and Forestry, 2013
This study aims to develop a screening approach for genetic tolerance to industrial pollution in Scots pine. The relationship between temporal variation in strength of genetic control on radial increment of seed orchard clones affected by air pollution ...

The radial increment of European ash (Fraxinus excelsior L.) under climate change, Ukraine

open access: yesJournal of Forest Science, 2020
The aim of the study was to compare the response of the radial increment of European ash (Fraxinus excelsior L.) in the Western and Eastern forest steppe of Ukraine to climate change. The growth-climate relationships were estimated for 1961-1987 and 1988-

Antifungal effect and reduction of Ulmus minor symptoms to Ophiostoma novo-ulmi by carvacrol and salicylic acid [PDF]

open access: yes, 2010
There are still no effective means to control Dutch elm disease (DED), caused by the vascular fungi Ophiostoma ulmi and O. novo-ulmi. Plant phenolics may provide a new strategy for DED control, given their known antifungal activity against pathogens and ...

The influence of carbon-containing greenhouse gases on the dynamics of radial increment of Pinus cembra and Picea abies in the conditions of the Gorgany Nature Reserve

open access: yesRegulatory Mechanisms in Biosystems, 2020
Based on the tree-ring chronology, we studied the radial increment of Swiss stone pine (Pinus cembra L.) and common spruce, or Norway spruce (Picea abies L.) as indicators of dendrochronological studies and, based on tree-ring chronology, reconstructed ...

Climate driven trends in tree biomass increment show asynchronous dependence on tree-ring width and wood density variation [PDF]

open access: yes, 2018
Tree growth is a key ecosystem function supporting climate change mitigation strategies. However climate change may induce feedbacks on radial growth and wood density, affecting the carbon sequestration capacity of forests.

Response of Gall oak (Quercus infectoria Oliv.) to pollarding in northern Zagros [PDF]

open access: yesتحقیقات جنگل و صنوبر ایران, 2016
This study aimed to investigate the response of Gall oak (Quercus infectoria Oliv.) to pollarding. Therefore, a less-disturbed stand (1.4 ha) and a pollarded stand (1.7 ha) were selected. Five rectangular plots (20×30 m) were established in each selected

Using longitudinal survival probabilities to test field vigour estimates in sugar maple (Acer saccharum Marsh.) [PDF]

open access: yes, 2008
Tree mortality is a major force driving forest dynamics. To foresters, however, tree mortality is often considered a loss in productivity. To reduce tree mortality, silvicultural systems, such as selection cuts, aim at removing trees that are more likely
