 Raman spectroscopy has been shown to be effective at distinguishing between biotic and abiotic stresses in plants. This method can accurately identify the presence of either one or both types of stress, even when they occur together. It can also be used to detect the presence of these stresses at different stages of development, allowing for more accurate diagnosis and treatment.
