The method includes emitting light at a first wavelength and a second wavelength into a plant sample with a chlorophyll meter; detecting the light after passing through the plant sample; generating an optical value responsive to a ratio of the percentage of transmitted light through the plant sample for the first wavelength and the second wavelength; and determining chlorophyll content based on the optical value compared with an optical/absolute chlorophyll relationship that was determined by a matched combination of extraction method, extraction solvent, spectrophotometric equation, and spectrophotometer resolution, wherein the optical/absolute relationship is one of a plurality of different optical/absolute relationships that a user may select from for different species. These relationships may link in situ optical measurements with in vitro chlorophyll concentration for display on a chlorophyll meter in units of mass or moles of chlorophyll per unit area or mass of tissue."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Chlorophyll meters and related method","description":"A method, system, and apparatus for determining chlorophyll content of a plant sample.
