Definition of annual ring in English:

annual ring

noun

A ring in the cross section of the stem or root of a temperate woody plant, produced by one year's growth.
Example sentencesExamples
- It was concluded from structural observations that duration of cambial activity is longer in trees with broad annual rings than in trees with narrow rings.
- The flora present in the fossil record compares with that in the tropics today; there are no annual rings suggesting uniform growing conditions without seasonal fluctuations.
- The amount of tension wood in a section was quantified as the total area of all tension wood bands in the second annual ring, divided by the total area of the ring.
- There is no way to tell the age of a tree without counting the annual rings, but exposing the annual rings is usually fatal.
- On islands C and D, we made annual ring counts on buried stem and root material so that a developmental sequence could be determined.
- We also measured the diameters of our living experimental trees, and extrapolated age based on the correlation between annual rings and circumference of the trunk sections.
- Trees near treeline produce annual rings that vary in width and density in response to changing environmental conditions.
- Because trees put on different kinds of wood in early summer and in late summer, dendrochronologists can count annual rings to figure out how old a tree is.
- The oldest tree in the present study had 135 annual rings at the stem base.
- When the climate is warm these organisms grow more and thus exist exhibit wider rings, and when it is colder their growth rings are narrower, which allows measurements across the annual rings to be used as a proxy temperature curve.
- The only way to tell the age of a tree is to count the annual rings.
- The annual rings in each sample are being counted in order to age each tree.
- We sampled one or two small cross-sections from each stem to determine annual ring widths.
- The widths and densities of annual rings in trees are partly controlled by climate, specifically temperature, precipitation, and snow cover.
- Before 1940, the annual ring increment declined as expected with altitude as the tree line was approached; after 1940, there was no such decline at all.
- For each core, we counted the annual rings to determine the initial year of growth.
- The annual rings of the trees we sampled were narrower than those reported previously for this site.
- Mean annual ring widths for mature podocarps range up to 1 mm in South Island, and for araucarians and podocarps in North Island, up to 2.2 mm.
