Abstract
The study aimed to assess the impact of varying Indole-3-Butyric Acid (IBA) concentrations on the rooting efficacy of Carnation (Dianthus Caryophyllus L.) cuttings within a controlled greenhouse setting. Different concentrations of IBA were applied to selected Carnation cultivars to stimulate root development. The greenhouse environment maintained controlled conditions, regulating temperature, humidity, and light to mimic optimal growth settings. The study focused on observing and analyzing rooting responses, particularly concerning root initiation, elongation, and biomass accumulation. Results indicated a distinct relationship between IBA concentrations and the rooting efficiency of Carnation cuttings. Lower concentrations displayed negligible effects on root development, while moderate concentrations significantly stimulated root initiation and elongation. Surprisingly, excessively high IBA concentrations led to reduced rooting responses, suggesting a hormetic effect on root growth. Morphological assessments highlighted that optimal IBA concentrations fostered vigorous root systems characterized by increased length, number, and mass of roots. This research underscores the pivotal role of precise IBA application in promoting successful rooting of Carnation cuttings, especially in controlled environments. The findings provide crucial insights for refining propagation techniques tailored specifically for Carnations, offering guidance to growers in optimizing IBA concentrations for efficient and sustainable cultivation practices in the floriculture industry. Further investigations delving into the prolonged impacts of IBA on overall plant growth and development would deepen the understanding derived from these findings.
