که نشان­دهنده اثر آنتاگونیستی این دو عنصر است. همچنین ترکیبات فنلی این گیاه در پاسخ به تیمار 1/0 میکرومولار مولیبدن به طور چشمگیری افزایش یافت. بنابراین به نظر می­رسد بهترین سطح مولیبدن برای رشد گیاه و تولید ترکیبات فنلی، سطح 1/0 میکرومولار مولیبدن است. </span></span></b></span></span></span></span>
<span style="font-size:12pt"><span new="" roman="" style="font-family:" times=""><span style="font-size:10.0pt">Plants need essential elements for growth and development. Nutritional management of nutrients can be effective in the production and quality of medicinal and aromatic plants. Molybdenum is a micronutrient that plays an important role in the enzymatic systems of plants. It is also considered a heavy metal, and excessive amounts are stressful for plants. In this study, the effect of molybdenum treatment (0, 0.01, 0.1 and 1 μM) was investigated on the biochemical and morphological characteristics of <i>Achillea millefolium</i> L. in a completely randomized design in hydroponic culture. The results showed that 0.01 and 0.1 μM molybdenum concentrations compared to control had positive effects on most biochemical characteristics, including chlorophyll, carotenoids, anthocyanins, soluble carbohydrates, proteins and growth indices including plant leaf area, root and shoot dry weight. While a 1 μM concentration of molybdenum had a negative effect on soluble carbohydrates and root dry weight. Root and shoot molybdenum concentration increased along with molybdenum levels, but copper concentration was reduced, indicating the antagonistic effects of these two elements. Phenolic compounds in the plant also increased in response to 0.1 μM molybdenum. Therefore, it seems that the best molybdenum level for plant growth and phenolic compound production is 0.1 μM molybdenum.</span></span></span>
