Abstract:

This paper is a summary of literature reviews concerning the diversity of medicinal plants and the results of our many years studies. It includes scientific and practical justifications of the importance of monitoring species diversity of the studied object. Results of monitoring the species composition of wild medicinal plants in some areas of the southern slope of the Gissar Range are specified. As a result of studying 11 gorges (Gazhne, Safedchashma, Gusgarf, Shamal, Obi-Zugora, Gulobod, Yos, Yavroz, Semiganch, Odzhuk, Magov), 174 species of medicinal plants were found that belong to different botanical taxa. This number of plants includes representatives of 106 genera belonging to 46 families, among which representatives of the aster family predominate: Asteraceae (36 species), Rosaceae (19 species), Lamiaceae (16 species), etc. Compared with the number of known plants growing within the territory of the Republic of Tajikistan, the number of species found was 11.6%. In relation to the number of plants that are recognized as medicinal in the world, species diversity of the southern slopes of Gissar Range is less than one percent. However, the number of species is comparable to locations with similar climatic conditions.

Abstract:

The cultivated medicinal plant production covers only 4–6% of the demand for raw material of the pharmaceutical industry in Lithuania, suggesting that medicinal plant cultivation may be an alternative business for organic farming. Phenology and biological parameters (plant height in flowering phase, number of twigs, air-dry mass), occurrence of diseases and pests of some medicinal plants, as Thymus serpyllum, T. pulegioides and T. vulgaris were studied in the field collection at the Botanical Garden of Klaipeda university (Western Lithuania) in 2001–2006. It was established that the beginning of the vegetation period of T. pulegioides was the same in different years. The amount of precipitation and average air temperature at the beginning of vegetation had influence on the preparation time of medicinal material by thyme, especially T. pullegioides and T. vulgaris. Air-dry mass of T. pulegioides was by 4–18 g m-2 more than the mass of T. serpyllum and T. vulgaris. Pests infected Thymus by 4.5–8.8%; severity of diseases varied from 0.5 to 4.5% in different years.
