Relict tree The
oldest tree on the planet is considered ginkgo biloba. During the Mesozoic, it was widespread on Earth, especially in northern latitudes, in temperate climate areas with high humidity. Many of them were also on the lands of the present Siberia. After the ice age, only one species of ginkgo out of fifty survived. He lived to the present day.
The appearance of
Ginkgo is a very tall tree, capable of growing up to 30 m in length and 3 m in thickness. In young specimens of the crown in the shape of a pyramid, it becomes rascidian with age. It’s a leaf-fallen tree. Shortly before discarding, ginkgo leaves acquire a golden yellow color.
Botanists consider firs and pines to be distant relatives of the ginkgo. That’s just the leaves they have completely different. In ginkgo, they have the appearance of a bifurcated broad wedge-shaped plate. And rather resemble the leaves of ferns. However, initially scientists attributed the tree to coniferous plants, writing off the absence of needles to evolutionary development. Of course, that opinion was wrong. Common in ginkgo and conifer is only the relation to holosed plants.
is a dioecious tree. The fruits yield only female specimens. Male trees are noticeably slimmer than female trees, which are characterized by high scarcidity.
Seeds and pollen tree begins to form only for 25-30 year development. Its fruits resemble small apricots. In the East, they are commonly eaten.
The plant with hunting gives a root breed and is perfectly cut. This greatly contributed to his “survival”.
Ginkgo is a fairly durable tree. There are instances that are more than 1000 years old.
This tree is characterized by high resistance to industrial air pollution, viral and fungal diseases. Ginkgo is rarely affected by insects. It is undemanding in terms of soils as well. That’s probably why this tree is so durable.
In natural conditions, ginkgo grows predominantly in eastern China and Japan, where coniferous and broadleaf trees are adjacent to forests. In other places this relic has already been planted by a man.
In the East it is revered as a sacred tree and considered a symbol of longevity. Ginkgo can be seen at almost every temple. During the leaffall period, the inhabitants of Japan worship ginkgo and collect fallen leaves respectfully.
This tree is the only plant known to scientists that contains specific substances bilobalids and gyncoholides. They have unique properties, whereby ginkgo leaves are actively used in medicine to prevent and treat a number of ailments.
