Coniferous Difuse Porous Ring Porous


Wood anatomy and tree growth

Wood Anatomy and Tree Growth: ________

(coniferous trees)

Hardwood

diffuse porous

(deciduous trees)

Hardwood

ring-porous

(deciduous trees)


Wood anatomy and tree growth

Wood Anatomy and Tree Growth: ________

Picea Pinus Taxus Tsuga

smithiana walichiana baccata dumosa


General ring structure

Wood Anatomy and Tree Growth: ________

General Ring Structure


Wood anatomy and tree growth

Wood Anatomy and Tree Growth: ________

Abies spectabilisCupressus torulosa Juniperus recurva


False ring

Wood Anatomy and Tree Growth: ________

False Ring

Cells leading into the false ring will gradually decrease in size and then gradually increase back to earlywood cells.


Wood anatomy and tree growth

Definitions:_

Parenchyma: thin walled tissue concerned primarily with the

storage and distribution of carbohydrates.

Terminal Parenchyma: the last parenchyma formed in a

years growth. In some diffuse porous species it is all that

Appears to denote the limit of a ring.

Tree-Ring: The annual increment of zylem growth

produced around a trees’ circumference in one year.

Earlywood: springwood. The xylem cells formed during

The beginning of the growing season.

Latewood: the xylem cells formed during the mid-end of

The growing season.

Resin Canals: tubular space surrounded by secreting

cells bearing resin in certain softwoods.

Traumatic Resin Canals: resin canals supposedly arising

From injury.

Annual Increment: The radial xylem growth produced

in a single year. Commonly measured to the nearest

0.001 mm.

Rhododendron Acer Sorbus

arboreum pectinatum microphylla

Betula Castanopsis Quercus Juglans

utilis hystrix semicarpifolia regia


Oak ring structure

Wood Anatomy and Tree Growth: ________

Oak Ring Structure.

Oaks rarely have missing rings but they can have very compressed growth.


Offset across rays

Wood Anatomy and Tree Growth: ________

Offset Across Rays

Oak often exhibits an offset in the rings across rays.


Wood anatomy and tree growth

Definitions:_

Limiting Factors: Conditions of a trees environment that

Have the most control on the rate at which a tree grows.

When all limiting factors

are sufficient growth is

unimpeded, when any

single limiting factor

falls below or near the

minimum requirement

for a tree species in a

specific environment

then growth of the tree

is negatively effected.


Auxin model

Wood Anatomy and Tree Growth: ________

Auxin Model

Growth hormone is produced in the canopy of the tree and trickles down the trunk initiating ring growth around the stem.


Locally absent rings

Wood Anatomy and Tree Growth: ________

Locally Absent Rings

Rings may be locally absent along the length of the tree.

Wood anatomy and tree growth

Definitions:_________________________________________________

False Ring: an incomplete start of final latewood development.

Locally Absent Ring:(LAR) an incomplete growth layer.

Time Series: An orderly sequence of events or measurements

that may change over time.

Biological Growth Curve:

The average radial growth

of as tree as measured over

time.

Indices:Relative annual

growth variations that

no longer vary with the

age of tree.


Wood anatomy and tree growth

Definitions:_________________________________________________

Chronology: A time series of mean growth measurements

from a specific site and species.

Master Chronology: A precisely dated mean chronology.

Climate:Seasonal conditions of precipitation and temp-

erature measured in months or years or centuries.

Response Model: percent climate expressed in tree-rings.

Paleoclimate: Past climate prior to instrumental record

keeping.

Paleomaterial: Preserved specimens of datable material

that can be used in building longer chronologies than

one can build from living trees.


Wood anatomy and tree growth

Wood Anatomy and Tree Growth: ________

Complacent and

sensitive tree-ring growth.


Wood anatomy and tree growth

Definitions:_

Standardization: The process by which the biological

growth curve is removed from the individual raw ring width

measurements producing a

new time series of index

values (indices). These

dimensionless values of year

to year variation are commonly

calculated either by division or

subtraction of a raw annual

increment by the mean biological growth curve value for the

same year (e.g., It = Rt/Gt ).
