Evaluation of soil physical and chemical properties And their recpect with essential cones of Juniperus Communis in Mountainous Rangelands of Hezarjarib - Mazandaran province

Considering the characteristics of growth location and plant location in the wild are of major factors that could affect the amount and quality of essences. Juniperus Communis is a type of plant that is always green and belongs to Cupressaceae. This plant is of the most important plants in the mountain plant-growing places of. The present research studied the essences of cone of the plant in summer meadows of Hezar Jarib in Behshahr. Firstly, cones were collected from the desired bases in height of 1950, 2050, 2150 and 2250 meters above sea level. Afterwards, the collected samples were dried in the open air under the shade. The essences of the plants were obtained using water distillation by the Clevenger and the components of the essence were identified using GC/MS machine. Data analysis was carried out through SPSS software. Based on the results, 60 components were identified in the essence of cone which Sabinene, α-pinene, Limonene, Terpinen-4-ol and Germacrene D had the most amount of essence in the meantime. Moreover, the results indicated that weight efficiency of essences in the bases was enhanced from the plant-growing place number 1 to plant-growing place number 4. The components of α-Pinene, γ-Terpinene, α-terpinolene and γ-elemen were also affected by the plant-growing places but there were no more significant differences in other components of intera-plant-growing places.In addition, results indicated a significant correlation between some soil elements and components of the essential oils.
