Global food security faces threats from plant stress caused by environmental factors. Traditional assessment methods are often invasive, time-consuming, and lack temporal resolution.
A novel developed nondestructive optical sensing method offers real-time insights into plant stress induced by light intensity, water scarcity, nutritional deficiency, and pathogen infection. This approach captures the values of the optical transmission coefficients, representing optical responses through the leaves of the plants, and presents them in graphs depicting the time dependence of circadian rhythms. The method, tested on various plants under diverse stressors, reveals distinct circadian rhythm changes, successfully detecting nutrient deficiencies, early pathogen presence, and metabolic shifts.
This innovative approach, providing continuous monitoring without causing harm to plants, holds significant potential for advancing plant research and improving agricultural practices.
