Abstract

Rapid changes in the agricultural sector in the past two decades have given rise to several new technologies and superior products including genetically modified crops; the identification of which still requires robustness and rapidity. In this work, we report the use of continuous wave terahertz (CW THz) spectroscopy as a means to identify biomechanical changes at the tissue level based on systemic dehydration. We have also identified the factors affecting this progression and propose a biomechanical model towards genetic discrimination in plants. Our results indicate that within the same family, factors such as cell size and age, tissue composition, hydration retention capacity and water percentage to cell volume ratio affect the systemic dehydration in the plant and thereby show unique biomechanical profiles.
