The comparision of morphological and phytochemical evaluation in some population of Stachys lavandulifolia Vahl. in different provinces under field conditions

In this study due to evaluate the morphological and phytochemical diversity of Stachys lavandulifolia Vahl. essential oils, the seeds of six populations of plant from Azerbaijan Province (Damraji and Gereh Zagh), Alborz (Gachsar), Qazvin (Alamut), Isfahan (Tangeh Saiad) and Lorestan (Nour Abad Delfan) were obtained from gene banks of Research Institute of Forests and Rangelands (Tehran), so after that the aerial parts of plants were collected before flowering in July 2013, which were cultivated from the research farm of Alborz province. The essential oils were obtained by hydro distillation method and were analyzed by GC and GC/MS. The results of variance analysis were showed significant differences in plant height, crown diameter, stem diameter, leaf length and width, number of leaves per plant and dry weight, respectively. The highest plant height (103.9 mm), stem diameter (3.6 mm) and number of leaves per plant (19) were showed in Alborz population (Gachsar) and the populations were classified in to two groups. Three components explain 89.6% of variation of all data and some traits such as stem diameter, leaf number and fresh and dry weight were attributed to first component. The lowest (0.015%) and the highest (0.049%) yields belonged to the Alamut and Gereh Zagh population, respectively. The composition of γ-terpinene, β-pinene, α-Pinene, germacrene-D and bicycle -germacrene were dominant in all essential oils of plant in different regions.
