This observational analysis evaluates the impact of varying electrical conductivity levels on morphological and physiological traits in chrysanthemum, suggesting enhancements in yield.
The present study investigates the influence of different electrical conductivity (EC) levels (0.5 EC and 1 EC) on the morphological, physiological and yield parameters of chrysanthemum grown under an aeroponic system. Significant differences were observed in plant height (V2 - 37.34 cm), stem diameter (V1 - 1.92 cm), number of leaves, internodal length, root length (V2 - 44.31 cm), root fresh and dry weight (V5 - 10.15 g), fresh and dry weight of the plant (V2 - 140.61 g), leaf area, transpiration rate, photosynthetic rate, stomatal conductance, total chlorophyll content and biochemical parameters such as soluble protein content (V5 - 67.29 mg g-1), catalase activity (V5- 38.81 μg H2O g-1 min-1) and peroxidase activity. Flowering characteristics, including number of flowers per plant (V4 - 56.94 number), flower diameter (V3 - 6.62 cm), vase life and weight of cut stem (V3 - 5.53 g), were also significantly affected. The results indicate that the aeroponic system with optimized EC levels enhances growth and flowering performance in chrysanthemum.
