Many of the active constituents of drug or medicines were originally derived from medicinal plants. Iranian Borage are still being used in regular basis. Selenium (Se) is an essential mineral nutrient for animal and human growth. The aim of this research was to determine the effect of (2, 4, 8 and 16 mg L) of as sodium selenate (NaSeO) and as sodium selenite (NaSeO) on some important properties of Iranian Borage in factorial based on Randomized Complete Block Design via four steps: 2 true leaves stage, ten leaves, 2 weeks and 1 week before flowering. The traits were evaluated during flowering period. Results showed that the highest shoot fresh and dry weight and shoot length, total alkaloid, essential oil percentage were obtained by 4 mg L sodium selenate at the end of flowering. In addition, 4 mg L sodium selenate concentration significantly improved flower yield (diameter, number, weight). The plants were treated with 8 mg L sodium selenate, the higher total phenols and flavonoids, antioxidant activity, soluble sugars, root and fresh weight was seen at end of flowering. When the plants were sprayed with 4 mg L sodium selenite higher total chlorophyll was observed at full of flowering. 16 mg L sodium selenite released the maximum Se acclimation in the petals. 20 composites were discovered containing ɑ-Pinene (23.61%) with sodium selenate in 4 mg L. Generally, selenium sources significantly improved morpho-physiological and phytochemical.
许多药物或药品的有效成分最初都来源于药用植物。伊朗琉璃苣仍在常规使用。硒 (Se) 是动物和人类生长所必需的矿物质营养物质。本研究的目的是确定（2、4、8 和 16 mg/L）硒酸钠 (NaSeO) 和亚硒酸钠 (NaSeO) 对伊朗琉璃苣某些重要特性的影响，采用基于完全随机区组设计的因子设计，分为四个步骤：2 片真叶期、10 片叶期、开花前 2 周和 1 周。在开花期对性状进行评估。结果表明，在开花结束时，4 mg/L 硒酸钠处理的地上部鲜重和干重、地上部长度、总生物碱、精油百分比最高。此外，4 mg/L 硒酸钠浓度显著提高了花产量（直径、数量、重量）。在开花结束时，用 8 mg/L 硒酸钠处理的植物总酚和类黄酮、抗氧化活性、可溶性糖、根和鲜重较高。当植物喷施 4 mg/L 亚硒酸钠时，在花满期观察到总叶绿素最高。16 mg/L 亚硒酸钠在花瓣中释放出最大的 Se 适应能力。在 4 mg/L 的硒酸钠中发现了 20 种含有ɑ-蒎烯（23.61%）的复合物。一般来说，硒源显著改善了形态生理和植物化学特性。
