Contents of inorganic elements are very important traits in plants. Some of elements have causal effects on plant growth. Their effects on plant metabolism and therefore quality and quantity of essential oils is crucial. Thus, to obtain relatively good results, different parts of Rosa damascena Mill. genotypes were analyzed.
Plants were collected from different provinces including Tehran, East Azarbaijan and Golestan. They were cultivated in Institute of Forests and Rangelands. Samples were collected in May 2003.
For determination and comparative study on inorganic elements like Na, K, Mn, Ca, Mg, Zn, Cu, P and N used different apparatus like Induced Coupled Plasma (ICP), Kjeltce and spectrophotometer. Results from different genotypes on petals and sepals of Rosa damascena Mill. from different states like Tehran, East Azarbaijan and Golestan were as follows: Na (127.4-160.4 ppm), K (24.48-35.88 ppm), Mg (9.11-10.61 ppm), Ca (60.54-65.41 ppm), Mn (0.073-0.094 ppm), Zn (0.162-0.35 ppm), Cu (0.207-0.30 ppm), P (0.19-0.28 mg/kg) and N (0.95-1.77%) in petals, and Na (110.2-277.7 ppm), K (25.72-38.53 ppm), Mg (12.36-24.27 ppm), Ca (57.63-196.3 ppm), Mn (0.105-0.185 ppm), Zn (0.156-0.62 ppm), Cu (0.166-0.32 ppm), P (0.23-0.39 mg/kg) and N (2.26-2.90%) in sepals.
