Useful plants bioresources, resource science and ethnobotanical use skills.

Many factors determine need for a targeted, multifaceted study of natural plant resources, since the biological or economic productivity of plants depends on the parameters of the ecosystem. That is why it is very relevant to monitor, search for, and study biomorphological characteristics of those plants that will expand the range in nutritional, pharmacological or other directions. Medicinal, aromatic, melliferous, dye, spicy and poisonous plants or useful plants are just such plants. Potential use of useful plants are increased more and more, despite the fact that synthetic-chemical means are abundantly available in the modern medicine, cosmetics and culinary. This process is not surprising, because use of these is accompanied by multiple complications that does not happen when we use herbal means. The spectrum of pharmacologically active substances represented in plants formed during the ontogenesis with the strictly defined sequence, quantity and qualitative content. They have positive influence on living organisms and are stable, without the less counteraction, which is an actual task in modern medical practice. Therefore, it is necessary to preserve a biodiversity through ensuring in-situ and ex-situ/on farm. For the purposes of further consumption, raising awareness in conservation of genetic and varietal diversity and rational usage of the unique flora of Georgia is gaining the most importance. This can be observed along with intensification and sustainable use of ethno-botanical traditions and promotion of phytoproduction, based on the rights conferred by the Convention on Biological Diversity of which Georgia is a party. Our long-term experiments (1994-2023) and the obtained results refer to this actual problem. Ref. 8.
