Zhumeria majdae Rech. has been used as traditional medicine in southern part of Iran. Essential oils and extracts from different parts of the plant have allelopathic effects. Present study investigated allelopathic effects of Zhumeria majdae Rech. essential oil on germination percentage, pigment content (chlorophyll and carotenoid) and antioxidant enzymes (catalase and Guiacol Peroxidase) activities on two wheat cultivars, Azar2 and Sardari. Plants were grown in perlite and the 10- days treated plants were used for the measurements. Different concentrations of the essential oil were obtained by 2.5% Arabic Gum solution. Distilled water and 2.5% Arabic Gum solution were used as control. Results indicated that germination percentage, pigment content, and the two antioxidant enzymes activities of the species treated with Arabic Gum were equal to those of the species treated with distilled water. With increasing essential oil concentration, in both cultivars, the germination percentage and chlorophyll content decreased and the carotenoid content increased. In the presence of essential oil, catalase activity increased slightly in both cultivars. In conclusion, it could be stated that incremnet of pigment content and antioxidant enzymes activities reduce their harmful effects on growth and development of the species through lowering the Reactive Oxigen Species (ROS) concentration.

Zhumeria majdae is one of the important, endomic, unic medicinal plants of hormozgan province that its uses has been known from pasts by native people. In this investigation. constituents of essential oils of Zhumeria majdae collected from Sarchahan mounth of Hormozgan province at flowering stages and were determined with GC and GC/MS. Then, effects of different concentrations of essential oils prepared from leaves of Zhumeria majdae on Escherichia coli and Staphylococcos aureous were tested. Chromatography analysis (GC & GC/MS) showed that were 22 different compounds present in essential oils of leaves of Zhumeria majdae. The major compounds were Linalool (60.4), Camphor (26.5), Borneol (2.1), Geraniol (2.1), Limonene (1.3) and Camphene (1.2). In this investigation arabic gum solution was control and different dilutions of essential oil of Zhumeria majdae were treatments. The dilutions of essential oil (0 ,20 ,40 , 60 percent) on Staphylococcos aureous and the dilutions of essential oil (0 ,20 percent) on Escherichia coli had MIC property. The dilutions of essential oil (80 , 100 percent) on Staphylococcos aureous and the dilutions of essential oil (40 ,60, 80, 100 percent) on Escherichia coli had MBC efficacy. In this study, constituents of essential oils and antimicrobial potentials of Zhumeria majdae were determined.

In this project, Lavander species was identified by with study of morphological characteristics and flora of Phalastina,Turkey and Iranica,This species has recognized with scientific names of Lavandula officinalis, Lavandula vera, Lavandula aungustifolia. Studies have shown that origin of Lavander is Europea conteries, such as France and it was spred via florance and Venis fo different parts of the world. The best way to increased this plants are with grafts to longitiuate 5-8 Cm from plant 2-3 ages.In this project enough a number of 500 Lavander grafts prepared to up way. Using Auxin 5ppm for part grafts for 24 hours,which usin from Auxin took the root two weeks earlier ratio to witness group,After three month growth and control of Lavander grafts in green house, transvered to farm.The farm divided in compelet block random design and applied amount 0,50,100,150,200 kg per hectar ammonium nitrate in tree period to space two month,The farm irrigated with drop system, After five month took away ten plants in each part recorded heigh and plants canopy diameter, Plants cut with a pair of scissors. Average fresh weight, dry weight of ten plants in each part recorded after dispersed in green house.Extraction essential oil of dry plant with Clevenger.Analysis data in end of project with soft wares of computer. Result showed ammonium nitrate caused an increase in fresh weight, dry weight, height, plants canopy diameter, number of branches and essential oil. Plants products increased with increase ammonium nitrate. The high growth showed in 150-200 kg per hectar Ammonium nitrate caused to high growth. Although nitrogen didn,t effective directory on medicinal compound, But nitrate present in Chlorophyl moleucol, However presentation of nitrate cause spreaded of leaves and level to build increased compond hydrocabones.

Effects of various concentrations of essential oils (0, 2.5, 5, 10, 20, 50 and 100 percent) of Zhumeria majdae leaves collected from Sarchahan mountain on mitotic cell division and its stages in root cells of Allium cepa were studied in this investigation. Results showed that all of essential oil concentrations reduced the number of mitotic cells. The average of mitotic cells in control was 7.5 % and in 100% concentration was zero, and also prophase, metaphase and anaphase phases were reduced. The most of decreament was in prophase stage. There are many terpenes compounds in essential oils of Zhumeria majdae leaves.They are probably a major effective factor in decrease of mitotic cell division in Allium cepa roots.
