Tree stump, about 37 years after falling. After a tree has been cut and has fallen, the stump or tree stump is usually a small remaining portion of the trunk with the roots still in the ground. Stumps may show the age-defining rings of a tree. The study of these rings is known as dendrochronology. Stump sculpture by German artist Eberhard Bosslet
The roots grow in length and send out smaller lateral roots. At the end of the growing season, the newly grown roots become woody and cease future length expansion, but will continue to expand in diameter. However, unlike the above-ground portion of the plant, the root system continues to grow, although at a slower rate, throughout the dormant ...
[1] [2] The underlying physiological mechanism is that trees transfer water and sap from the roots to the leaves through their vascular cells, but in some trees as autumn begins, the veins carrying the sap slowly close until a layer of cells called the abscission layer completely closes off the vein allowing the tree to rid itself of the leaf. [3]
The term "log" is informally used in English to describe any felled trunk not rooted in the ground, whose roots are detached. A stump is the part of a trunk remaining in the ground after the tree has been felled, or the earth-end of an uprooted tree which retains its un-earthed roots.
Epicormic buds develop and grow when the upper parts of the stem (which normally produce inhibitory plant hormone analogues) are removed. Suckers refers to shoots growing from roots in response to felling to ground as seen in wild cherry or gean (Prunus avium) and aspen (Populus tremula) but also has been adopted in horticulture to refer to a ...
A tree throw or tree hole is a bowl-shaped cavity or depression created in the subsoil by a tree. They are formed either by the long-term presence and growth of tree roots or when a large tree is blown over (as a windthrow ) or has its stump pulled out which tears out a quantity of soil along with the roots.
One of which is cutting the branch back to a specific and intermediate point, called reduction cut, and the other completely removes a branch back to the union where the branch connects which the main trunk, called removal cut. [5] Reduction cuts is when you remove a portion of a growing stem down to a set of desirable buds or side-branching stems.
Plants that are intermediate may be called semi-deciduous; they lose old foliage as new growth begins. [10] Other plants are semi-evergreen and lose their leaves before the next growing season, retaining some during winter or dry periods. [11] Like a number of other deciduous plants, Forsythia flowers during the leafless season.
