Changing of some elements during phonological stages in Nitraria Schoberi L
Nitraria Schoberi L. from Nitrariaceae as pharmaceutical, industrial and fodder plants can tolerate harsh environmental conditions especially sandy and saline soil. This plant is natural sources of some important chemical components like schoberine nitraraine, dihydronitraraine, nitraramine, nitraroxine and etc. More than 25 Mha of salt affected land exists in Iran and this plant can offer an economic and practical alternative towards achieving saline land and water resources in order to produce natural chemical components for pharmaceutical industries. Changing in some elements (Nitrogen, Phosphor, Sodium, Potassium, and Calcium) during flowering and forming seed stages (2009) were investigated. Samples of the aerial part of Nitraria Schoberi collected in the Kashan region were dried, grained and analyzed in Laboratory. The results showed that elements level indices values including P, K, Ca and N were significantly differed among phenological stages but Na did not show any difference between two stages. Decreasing in P, K and N showed chemical component of this plant could change by sequence of phenological stages and finally these changes affect on quality of fodder and medicinal properties.
