Evaluation of physiological plant responses during altered environmental changes via fluorescence sensors

Tomato

Environmental changes such as abiotic stress factors can cause physiological alterations in plant development and hence, reduce yield. During the onset and stress formation, plant status and stress responses can be evaluated and quantified non-destructively by optical sensor to avoid major yield losses. Multiparametric techniques based on chlorophyll fluorescence and blue-green fluorescence emitted from surfaces enable monitoring changes for example in pigment composition and surface structure. Besides the assessment of physiological responses at leaf scale, our research focuses on fruit ripening and quality to gain a better understanding of optimized horticulture with the aim to support sustainability in fruit and vegetable production.
