Climate variations affect the growth period of young Tectona grandis Linn F. in the Amazon

open access: yesActa Botânica Brasílica, 2022
Climate change is expected to increase the occurrence of severe droughts in the tropics, and little is known about its influence on tree dynamics. Tree-ring width and remote sensing tools can help understand the impacts of climate change on tree growth ...

An interactive method for digital tree-ring width measurement [PDF]

open access: yesGeofísica Internacional, 2004
We present a new interactive method for tree-ring width determination. It uses a high resolution scanner and a PC. A program to process scanned tree-ring images was developed in Interactive Data Language (IDL 5.0) environment.

Factors affecting the radial growth of Juniperus foetidissima Willd. and J. excelsa M. Bieb. in central Anatolia

open access: yesJournal of Forest Science, 2021
Central Anatolia is one of the semi-arid regions of Turkey that does not offer very suitable conditions for the growth of trees. Tree growth is a process controlled by genetic, environmental and climatic factors. Trees record these signals, which provide

Inter-relations between tree-ring width and vessel features in black alder (Alnus glutinosa) [PDF]

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2015
From a long time ago, researchers in the fields of wood science, dendroclimatology and tree physiology were interested in variation of tree-ring width and vessel features within a tree.

Giant Sequoia Ring-Width Chronologies from the Central Sierra Nevada, California

open access: yes, 1992
Giant sequoia was one of the first species that A. E. Douglass examined in his pioneering tree- ring research. Recent attention to sequoia, stimulated by fire history studies in sequoia groves, has resulted in new ring-width chronologies based on both ...

Relationship between Ring Width and Tracheid Characteristics In Picea crassifolia: Implication in Dendroclimatology

open access: yesBioResources, 2014
Ring width represents the total width of cells in a growing season. Relatively few studies have identified which of the parameters, cell number, size, or wall thickness is the greater contributor to variations in ring width.

The use of X-ray method to study annual growth variation of Pinus eldarica [PDF]

open access: yesتحقیقات علوم چوب و کاغذ ایران, 2013
Using non-destructive methods to study forest productivity and wood quality as well as annual growth variations deserve special importance. In this regard annual growth changes of Pinus eldarica include width of the spring and summer rings and percentage

Cycle Analysis Method of Tree Ring and Solar Activity Based on Variational Mode Decomposition and Hilbert Transform

open access: yesAdvances in Meteorology, 2019
According to the correlation of tree ring and solar activity, the cycle analysis method based on variational mode decomposition (VMD) and Hilbert transform is proposed.
