Jamzad is a valuable and endemic medicinal plant. Boron and zinc are essential elements for the vegetative and reproductive growth of plants and have significant effects on yield, essential oil composition and the seed production of plants. To investigate the effects of the foliar application of zinc and boron on the growth, yield, seed production and phytochemical properties of , a study was conducted in a factorial experiment with three replicates in two consecutive years based on a randomized complete block design. The foliar application of boron (B) at three concentrations (control or distilled water, 0.4% and 0.8% as HBO) and zinc (Zn) at three concentrations (control or distilled water, 0.3% and 0.6% as ZnSO) was carried out. Our results showed that the foliar application of B resulted in a significant increase in the fresh and dry weights of plants, the dry weight of stems, drug yield, seed yield, seed germination and 1000-seed weight. At the same time, the application of B resulted in a significant decrease in seed emptiness. The fresh and dry weights of plants, drug yield, seed yield, 1000-seed weight and seed germination were also significantly improved by Zn foliar spraying compared to the control. Application of 0.8% B resulted in a significant decrease in seed emptiness by 14.16% and 22.37%, as compared to the control. The foliar spraying of B and Zn improved the total phenolic content, the essential oil content and the yield and antioxidant activity of . Moreover, B application generally concentrated more carvacrol in the essential oil (in the first experimental year). In contrast, no significant differences were observed between Zn treatments in carvacrol content and total flavonoids. The use of several microelements, such as B and Zn, could improve both the quantity and quality of . Additionally, improvement of seed set and seed quality by the foliar spraying of Zn and B may be useful for growing plants in arid and semi-arid areas.
Jamzad是一种珍贵的本土药用植物。硼和锌是植物营养生长和生殖生长所必需的元素，对植物的产量、精油成分和种子生产有显著影响。为了研究叶面喷施锌和硼对Jamzad的生长、产量、种子生产和植物化学特性的影响，基于随机完全区组设计，连续两年进行了一项有三个重复的析因试验。进行了三种浓度的硼（B）叶面喷施（对照或蒸馏水、0.4%和0.8%的硼砂）和三种浓度的锌（Zn）叶面喷施（对照或蒸馏水、0.3%和0.6%的硫酸锌）。我们的结果表明，叶面喷施硼使植物的鲜重和干重、茎干重、药材产量、种子产量、种子发芽率和千粒重显著增加。同时，施用硼使种子空瘪率显著降低。与对照相比，叶面喷施锌也显著提高了植物的鲜重和干重、药材产量、种子产量、千粒重和种子发芽率。与对照相比，施用0.8%的硼使种子空瘪率分别显著降低了14.16%和22.37%。叶面喷施硼和锌提高了Jamzad的总酚含量、精油含量以及产量和抗氧化活性。此外，施用硼通常使精油中香芹酚的含量更高（在第一个试验年份）。相比之下，锌处理之间在香芹酚含量和总黄酮方面没有观察到显著差异。使用硼和锌等几种微量元素可以提高Jamzad的数量和质量。此外，叶面喷施锌和硼提高坐果率和种子质量可能对干旱和半干旱地区的植物种植有用。
