Methods for estimating photosynthetic characteristics in plant canopies and systems and apparatus related thereto
First Claim
1. A method of determining photosynthetic characteristics in one or more plants, comprising:
- capturing a plurality of images of plant parts in said plants with one or more sensors, wherein the plurality of images comprises a first image comprising measurement of the fluorescence of the plant parts and a second image comprising capture of one or more reflectance images of the plant parts upon exposure to one or more lights; and
deriving information regarding a characteristic of photosynthesis of the plant parts by multiplying the plurality of images.

Abstract
Methods of determining and characterizing photosynthesis in plant parts of one or more plants includes capturing a plurality of images of the plant parts of the one or more plants with a sensor are provided. Fluorescence of the plant parts of the one or more plants can be measured by storing a sensor image of observed fluorescence. Light absorbed by the plant parts of the one or more plants can be estimated by observing red and/or infrared reflectance of the plant parts. A characteristic of photosynthesis such as linear electron flow in plant parts of the one or more plants can be derived using the measured fluorescence of the plant parts, the reflectance and the light absorbed by the plant parts, and/or the three-dimensional model comprising the plant parts of the one or more plants. Related apparatus and systems are also provided.
