Abstract: The present disclosure provides the use of a fluorescent imaging plate reader (FLIPR) high-throughput real-time fluorescence detection and analysis system in detection of calcium signals in plants, which successfully applies the FLIPR to the detection of calcium signals in plants, and increases the use of the FLIPR in the detection of calcium signals in plants. In addition, a method for detecting calcium signals in plants based on FLIPR provided by the present disclosure detects changes in calcium signals generated by stimulation of plants by an exogenous calcium signal CaCl2 solution, which is the basis of high-throughput real-time fluorescence detection of calcium ions in plants.

Abstract: Embodiments of this application provide a sensing method, a communication apparatus, and a communication system. The sensing method is applied to a first communication apparatus.
