STUDY AND CONSERVATION OF GENETIC MATERIAL FOR SOME MEDICAL PLANTS

Our country has a wide variation of ethero-oil and medicinal plants due to its favourable climatic-pedologic conditions. The biggest Surface of these plants lies in Castanetum Zones around 37% and Fagetum Zones around 27%. In a lot of rural zones, in order to gain maximal profits, the collection of ethero-oil and medicinal plants has been done out of norms and technical criterion, which has made possible that most of this natural property to go toward reduction and extinction. Study of some of the vegetation features and ecological conditions of ethero-oil and medicinal plants provides the possibility of conserving a considerable genetic material of them. A special attention has been paid to finding the best ways of reproduction and cultivation of Origanium vulgaris, Salvia officinalis, Lavandula officinalis . From their regeneration has been obtained a considerable amount of seeds that will be used at the right moment for their propagation, as the only way for the conservation of the genetic source in a natural controlled environment.
