Since Iran has always faced fluctuations and decreases in the rainfall, and on the other hand, the uncontrolled harvest of water resources have led to a more severe decline in the groundwater resources, the medicinal plants cultivation can help overcome the water deficit crisis. This study aimed at determining the ecological suitability of cultivation of four medicinal plants including damask rose (Rosa damascena Mill.), saffron (Crocus sativus L.), thyme (Thymus vulgaris L.), and lavender (Lavandula angustifolia L.) in 36 plains located in the Salt Lake (Namak Lake) catchment. The research methodology included the collection, reconstruction, and quality control of the information, climatic simulation, calculation of the agro-climatological indicators, and estimation of the agriculture share of water resources separately for each plain, estimation of the plant water needs, determination of the moisture balance, preparation of the suitability layers of cultivation, and finally overlaying the layers to produce the suitable/unsuitable agricultural lands for the cultivation of these plants. The climate simulation was performed by the strategic re-sampling technique to generate the different scenarios during the period 2011-2035. All the models under the different scenarios predicted a decrease in the rainfall and an increase in the maximum and minimum temperatures. The EC-EARTH model under the RCP2.6 scenario predicted the highest percentage of rainfall decrease (about 23%) and temperature increase. Due to the salinity and heat stress, the agricultural lands located at Sharifabad plain, northern parts of Qom-Kahak plain agricultural lands, eastern lands of Saveh plain, northern lands of Kashan plain, and southern lands of Varamin plain were unsuitable for the cultivation of all four medicinal species. The cultivation of saffron and damask rose in most of the plains of Salt Lake catchment was suitable or very suitable.

The Jujube tree is a valuable medicinal plant that is considered as an important traditional medicine. It is spreade in different parts of Iran with different climatic conditions so it has a wide ecological tolerance range. Jujube is being found from humid and low altitute region in Caspin Sea littoral to dry and deserty region in Yazd and Tabas and also Fars and Lorestan montains. The variety of Jujube locations shows genetic diversity of it which is being used in gardens and natural fields with differnce envirental conditions leading us to different quantity and quality of chemical components and ingredients needed for preparation of medicines, In additional protect of Jujube germinative is nessesary, because it is warnning in many ways.This study was executed for finding Jujube ecotype & genetic diversity in Iran in 1999-2002. Ecotypes of Jujube were found in 15 provinces of Iran and stool shoot from 29 regions planted in Badieii research station located in western part of Qom for morphologic and phenologic studies (every ecotype 5 stool shoot from 29 regions planted in Badieii research station located in western part of Qom for morphologic and phenologic studies (every ecotype 5 stool shoots). Characters of growth and birth orderly was recorded. Analysis of variance indicated that leaf lengh and width in every repeat had significant differences.
