Abstract:   (1417 Views)
Snapdragon (Antirrhinum majus) belongs to the Plantaginaceae family. While it is a perennial plant, it is often cultivated as an annual, especially in regions with cold winters. This study aimed to investigate the combined effects of different LED light spectra and carbon nanotube concentrations on the physiological characteristics of snapdragon plants. This experiment was conducted under controlled conditions using a CRD_ based factorial design with 4 replications. Treatments included various LED light combinations (white, blue, red, and their 80% blue light + 20% red light, 60% blue light + 40% red light, 40% blue light + 60% red light and 20% blue light + 80% red lightcombinations) and 3 concentrations of carbon nanotubes (control, 50 and 100 mg/liter). Evaluated parameters were chlorophyll content, stomatal conductivity, and chlorophyll fluorescence. Results indicated that both LED light spectra and carbon nanotubes, significantly influenced the growth and physiological responses of snapdragon plants. Specific findings include: LED light spectra had varying effects on chlorophyll content, stomatal conductance, and fluorescence. Generally, blue light enhanced vegetative growth, while red light influenced flowering and biomass accumulation. The combination of red and blue light often yielded optimal results. Carbon nanotubes, particularly at higher concentrations, affected stomatal conductance and fluorescence. Their interaction with light treatments further modulated plant responses. Chlorophyll content, a key indicator of photosynthetic efficiency, was significantly affected by both light and nanotube treatments. Stomatal conductance, which regulates gas exchange, was also influenced. Fluorescence measurements provided insights into the efficiency of light energy utilization in photosynthesis. Overall, this study demonstrated that the combination of LED lights and carbon nanotubes can be an edfficient tool for manipulating plant growth and physiology. The optimal light spectrum and carbon nanotube concentration varied depending on the parameter being investigated. These findings contribute to a better understanding of the complex interactions between light, nanomaterials, and plant growth, and have potential applications in controlled environment agriculture and plant biotechnology.
