A method and an instrument for determining a nutritional state of a plant with respect to one or more nutrients is provided. The method comprises the steps of recording a time series of a fluorescence induction signal of a tissue sample of the plant using a fluorometer device to obtain signal data, wherein the time series at least comprises signal data within the rising portion of the fluorescence induction signal, and determining the nutritional state from an empirical model applied to the signal data, wherein the empirical model is based on pre-recorded reference data and relates nutritional states to shape-related features in the progression of the fluorescence induction signal.

摘要:
[Problem] To accurately check a usage status of a medical product such as a damage status of the medical product or existence or nonexistence of the medical product. [Solution] A medical product (80) is configured to include a light-emissive septum (83) (constituent member) which includes a luminescent agent emitting near-infrared fluorescence according to irradiation of excitation light on a surface thereof. Even in a case where a portion of the septum is separated as a core (83a) (separate piece) due to damage, the luminescent agent is also included on a surface of the core. A medical product usage status checking apparatus (10) is configured to include a medical product which emits the near-infrared fluorescence, an irradiation unit (130) which irradiates the medical product with excitation light which excites the luminescent agent, an optical filter (140) which blocks the excitation light and transmits the near-infrared fluorescence emitted by the luminescent agent, a camera (15) (imaging unit) which receives the near-infrared fluorescence passing through the optical filter, and a monitor (160) (display unit) which displays an image captured by the camera. An image based on the near-infrared fluorescence of the septum is displayed on the monitor and in a case where damage occurs in the septum, an image based on the near-infrared fluorescence of the core is displayed on the monitor.
