To investigate the effects of different nitrogen sources including ammonium nitrate, asparagine, and glutamine in five concentrations of 0, 50, 100,150, and 200 mg l-1 on some physiological and biochemical characteristics of rosemary (Rosmarinus officinalis L.), an experiment was conducted in a completely randomized design with five repliacations. The indices including plant height, shooting rate, number of leaves, necrotic leaf size, chlorophylls a, b, and total chlorophyll content, and the content of carotenoids, phenols, and flavonoids were measured. The results showed that the nitrogen sources significantly (P≤0.01) affected the all measured indices except the necrotic leaf size. The results of means comparison showed that the highest shooting rate and number of leaves were obtained at 100 mg l-1 of glutamine and asparagine and the highest plant height was obtained at 200 mg l-1 of ammonium nitrate. Also, the highest amount of photosynthetic pigments was obtained at 50 mg l-1 of asparagine and the highest amount of phenols and flavonoids was related to 200 mg l-1 of glutamine. In general, the results showed that the various nitrogen sources studied could positively and significantly improve the morphological and physiological characteristics of rosemary under in vitro conditions.

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.
