Ringkasan	Chlorophyll fluorescence is a non-invasive optical measurement of how efficiently the photosynthetic machinery converts absorbed light into chemical energy (photosynthesis) or heat and light (fluorescence). When photosynthesis is inhibited by stress (drought, cold, salt, pests), chlorophyll fluorescence increases because excitation energy cannot be used for photosynthesis and must be released as light or heat. Fluorescence parameters (Fv/Fm, OJIP curves) act as sensitive, rapid indicators of photosynthetic stress, enabling early detection of plant dysfunction before visible symptoms appear.	Root Architecture Analysis is a quantitative method in agronomy and plant science that characterises the spatial configuration, branching pattern, and geometric properties of a plant's root system. By measuring parameters such as total root length, lateral root density, root angle, and root tip number, researchers link below-ground structural traits to nutrient and water acquisition efficiency, soil penetration capacity, and ultimately to crop productivity and stress tolerance.
