Used in plant physiology and agricultural research to measure the activity of RuBisCO, a key enzyme in the photosynthetic process. Helps assess plant photosynthetic efficiency under varying environmental conditions such as drought, heat, or high salinity. Widely applied in studies of crop improvement, stress response, and carbon fixation. Enables researchers to evaluate how genetic modifications or treatments affect RuBisCO function, supporting the development of higher-yielding or climate-resilient plant varieties. Also used in ecological studies to compare photosynthetic performance across different plant species or ecosystems.
