Liana

Vines are climbing plants with usually verholzendem trunk, the roots in the ground and climb up on trees or other vertical structures. Lianas do not belong to a taxon, but are species from different plant species.

The lianas, several types can be distinguished: Some climbing plants entwine the carrier into more or less numerous turns ( winds or trailing plants ). The direction of rotation may depend on the type of plant or the hemisphere of the site. Climbing plants usually form sprouting or blattbürtige Rank organs. Other lianas keep (eg Virgin vines) fixed with adventitious roots ( root climbers, such as Common Ivy) or adhesive discs. Spreizklimmer strut their branches with the carrier plants by lateral spreading, with auxiliary organs such as climbing hairs or spines prevent slipping back. This climbing principle is to be found at about roses or blackberries.

The vines escape the lack of light in the vicinity of the ground to have to train without a massive trunk. They're not freeloaders, so escape the carrier neither plant nutrients or water. For their impairment may by light deprivation, water and nutrient competition come in the root area or the weight of the vine itself, especially if they are already weakened by illness. Lianas may form about half of the leaves surface. Many lianas form of aerial roots.

Especially numerous lianas are represented in the tropical rain forest. In Central Europe, among others, come Vines, ivy, blackberry, clematis and honeysuckle before.
