en Effects of benzyl adenine and monopotassium phosphate on morphological and physiological traits of potted Anthurium Effects of benzyl adenine and monopotassium phosphate on morphological and physiological traits of potted Anthurium باغبانی Horticulture پژوهشي Research <div style="text-align: left;">Anthurium andreanum is a popular perennial ornamental plant with both potted and cut-flower cultivars, known for its colorful and attractive spathes. This study focused on the potted cultivar ‘Red’ and aimed to evaluate the effects of benzyl adenine (BA) and monopotassium phosphate (MKP) on growth, flowering, pigment content, and leaf mineral elements. A factorial experiment arranged in a completely randomized design with three replications was conducted, applying BA at 0, 100, and 200 mg L⁻¹ and MKP at 0, 20%, and 40%. Results showed that combined application of 40% MKP and 200 mg L⁻¹ BA significantly accelerated flowering, reducing days to first flower by 31% compared to control. Flower number increased by 175% under this treatment. Leaf number and length also improved, with a 107% increase in leaf number at 20% MKP combined with 100 mg L⁻¹ BA. Photosynthetic pigments, including total chlorophyll and anthocyanins, were significantly enhanced. Anthocyanin content peaked with 40% MKP + 200 mg L⁻¹ BA, showing a 52% increase over control. Leaf phosphorus and potassium concentrations increased by up to 24% and 43%, respectively. In conclusion, the combined application of BA and MKP led to considerable improvements in most of the evaluated traits in the potted cultivar ‘Red’ of A. andreanum, highlighting their potential for enhancing overall plant performance under commercial cultivation.</div> Anthurium andreanum is a popular perennial ornamental plant with both potted and cut-flower cultivars, known for its colorful and attractive spathes.
