There are some tropical vines that develop skototropism, and grow away from the light, a type of negative phototropism. Growth away from light allows the vine to reach a tree trunk, which it can then climb to brighter regions. [6] The vine growth form may also enable plants to colonize large areas quickly, even without climbing high.
A liana is a long-stemmed woody vine that is rooted in the soil at ground level and uses trees, as well as other means of vertical support, to climb up to the canopy in search of direct sunlight. [1] The word liana does not refer to a taxonomic grouping, but rather a habit of plant growth – much like tree or shrub.

Branch attachment in common ash Fraxinus excelsior L. Figure 1: Anatomical drawing of the wood grain of a branch attachment in a tree. Initially branches are mechanically attached to the trunks of trees by forming interlocking wood grain patterns at the top of the joint, within what is known as 'axillary wood' (Fig. 1). [1]
The vine attaches to supports by tendrils. The stems, called twigs, grow through their tip, the cauline apex. A branch consists of several internodes separated by knots, which grow the leaves, flowers, tendrils and between-core and where to train future buds. During their hardening, the twigs become woody branches that can reach a great length.
“Old vine” is a commonly used term in the world of high-end wine. It seems to imply something regal about a wine, a greater sense of depth, concentration or profundity of character.
Vine training system used in the Jerez region of Spain for Sherry wine grapes. This involves pruning the vine to two branches with one short "thumb" branch that only has a couple buds and one long "stick" branch with around 8 buds that alternate each year between which side is the "thumb" and which is the "stick".
Leaves tend to have a shorter life span than the stems or branches that bear them, and when they fall, an area at the attachment zone, called the abscission zone leaves a scar on the stem. In the angle ( adaxial ) between the leaf and the stem, is the axil .
