    摘要: 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.
