Difference between spring wood and autumn wood

Main difference

The main difference between spring and fall wood is that spring wood is wood that is formed in a favorable season, while autumn wood is wood that is formed in an unfavorable season.

Spring wood vs. fall wood

Spring wood was formed in a favorable season and is also called early wood, while autumn wood is wood that is formed in an unfavorable season and is also called late wood. Spring wood makes up most of the annual ring, while fall wood makes up a narrow strip in the annual ring. Spring wood is present at the beginning of the annual ring, while autumn wood is present at the end of the annual ring. Springwood forms many xylem vessels with wider cavities; on the other hand, autumn wood also contains xylem vessel cavities but they are narrow. Xylem fibers are present in smaller numbers in spring wood, in contrast, autumn wood has abundant xylem fibers. Spring wood is lighter in color, while fall is darker in appearance. Spring wood has a lower density, while autumn wood has a higher density. Spring wood is formed when the cambium is active; on the other hand, autumn wood is formed when the cambium is less active.

Comparative chart
Spring wood Autumn wood
The cambium becomes more active during the spring season and properly forms xylem vessels with larger cavities called springwood, also known as earlywood. Cambial activity slows down in the winter season and gives growth to the narrow elements of the xylem known as autumn wood, also called late wood.

What is Spring Wood?

The cambium becomes more active during the spring season and properly forms xylem vessels with wider cavities called springwood. Springwood is also known as earlywood. Produces a large number of xylary elements. Spring wood is lighter in color. This wood has a lower density in a tree. Spring wood makes up most of the annual ring, as it also starts the annual ring. Spring wood is present at the beginning of the annual ring. Xylem fibers are present in smaller numbers in spring wood. Spring wood is formed when the cambium is active and the cambium is activated during favorable conditions such as the spring season. This season promotes the growth of cambium and spring wood. In oak and ash,

What is Autumn Wood?

Cambial activity slows down in the winter season and gives growth to the narrow elements of the xylem known as autumn wood. Autumn wood is also called late wood. Produces fewer xylary elements. This wood has a higher density than wood. Autumn wood is darker in color. Autumn wood comprises a thin stripe on the annual ring when the annual ring ends. Autumn wood is present at the end of the annual ring. Xylem fibers are present in abundance in an autumn forest. Fall wood is formed when the cambium is less active and the cambium has fewer assets during unfavorable conditions such as the winter season. This season limited the growth of cambium and fall wood. Fall wood blocks can be turned into wooden pathways and slabs of wood in a processor. Autumn wood can be used as fuel for forges even though it burns slowly like all types of wood fuel.

Key differences

  1. Spring wood was formed in a favorable season and is also called early wood, while autumn wood is wood that is formed in an unfavorable season and is also called late wood.
  2. Spring wood is present at the beginning of the annual ring, while autumn wood is present at the end of the annual ring.
  3. Spring wood makes up most of the annual ring, while fall wood makes up a narrow strip in the annual ring.
  4. Springwood forms many xylem vessels with wider cavities; on the other hand, autumn wood also contains xylem vessel cavities but they are narrow.
  5. Xylem fibers are present in smaller numbers in spring wood; in contrast, autumn wood has abundant xylem fibers.
  6. Spring wood is lighter in color, while fall is darker in appearance.
  7. Spring wood is formed when the cambium is active; on the other hand, autumn wood is formed when the cambium is less active.
  8. Spring wood has a lower density, while autumn wood has a higher density.
Final Thought

The above discussion concludes that spring wood is wood that was formed in a favorable season and also called early wood, while autumn wood is wood that was formed in an unfavorable season and also called late wood.
