The growth layer of I year, as viewed on the cross section of a stem, branch, or root. One year's growth consists of a layer of lighter-colored wood (springwood) and a layer of darker-colored wood (summerwood).
A layer of xylem and phloem produced during one season of growth.
The pattern created by one year's growth on a cross-section of a tree trunk, formed by the bands of springwood and summerwood.
The layer of wood produced by a single year's growth of a woody plant.
an annual formation of wood in plants as they grow
a year worth of secondary xylem growth
visible circle in x-section of tree produced by one year's growth
Shows the growth layers of each year of wood production throughout the tree's life. Can be seen on the cross-section of a branch or stem.
Annual rings are concentric circles that appear on tree trunk cross-sections that mark the end of a growing season. These rings show whether the tree grew a lot or a little that year.
Bands that show tree growth for one year, as viewed on the cross section of a trunk core sample or stump. Can be counted to determine a tree's age.
Trees in climates where growth stops or slows during a portion of the year will form annual rings which can be read to determine tree age and rate of growth. The science of dendrochronology studies tree rings to infer knowledge about past climatic conditions, based on the fact that trees will form wider annual rings during seasons when growing conditions are favorable and narrow rings when not. Annual rings are highly visible in tree species that form less dense wood during favorable growing conditions early in the season and denser wood during less favorable conditions later in the year. In some tree species this differentiation does not occur and annuals rings are difficult to see. In tropical species, growth never, or seldom, ceases and annual rings may not be apparent.
The combination of one earlywood layer (light colored) and one latewood layer (dark colored) seen in a cross-section of a tree. One annual ring usually represents one year of growth.
The sleeve of wood put on each growing season over the previous year's wood and under the bark on both stern and branches. Consists of spring wood and summer wood, the latter usually darker and thereby showing up as a ring in cross section.
Growth rings seen in the horizontal cross section of a tree.
