Investigation of morphophysiological traits, essential oil percentage and some elements of Artemisia sieberi affected by changes in habitat soil (case study: Hoz Soltan lake in Qom)

In this research, the plant samples of Artemisia were collected at full flowering stage from three natural habitats in North of Qom province, Iran. Morphological characters were plant height, the number of tiller, large and small diameter of canopy, root length, root weight. The samples were analyzed for their soluble sugars, proline, chlorophyll, Na, K, Mg, Ca and Cl content and percentage of essential oil. Analysis of variance indicated that habitats significantly influenced flowering shoot, stem weight, root weight, total dry matter weight, soluble sugars, proline, chlorophyll a, Na, K, Mg and Cl at P≤ 0.01, and chlorophyll b and Ca at P ≤ 0.05. The means of traits indicated that flowering shoot yield with 48.3 g/plant, root weight with 70.2 g/plant, total dry matter yield with 234.6 g/plant and the percentage of essential oil with 0.75% were maximum. The highest soluble sugars, proline, Na, K, Mg, Ca and Cl with 0.68 mg/lit, 1.17 mg/lit, 8.8 ppm, 15.7 ppm, 4.7 ppm, 22.86 ppm and 35516.2 ppm means were observed. The results showed that Artemisia is an endurable plant in a low salty conditions and it can increase regulator osmolytes and reduce yield to suffer salty conditions.
