Plant treatment based on morphological and physiological measurements

A plant treatment system comprising:

• one or more nozzles mounted to a vehicle traversing through a field, the one or more nozzles configured to release a plant treatment onto one or more plants in the field;
• one or more sensors mounted to the vehicle, the one or more sensors configured to capture a first physiology measurement for a plant in the field at a first time and a second physiology measurement of the plant at a second time, wherein the first physiology measurement comprises a plurality of pixels representing an expressed phenotype of the plant before a plant treatment and the second physiology measurement comprises a plurality of pixels representing the expressed phenotype of the plant after the plant treatment;
• a computer communicatively coupled to the one or more sensors, the computer executing a set of instructions that, when executed, cause the plant treatment system to:
• determine an expression value quantifying a difference between the first physiology measurement and the second physiology measurement, the difference representing a change in the expressed phenotype induced by an effect of the plant treatment;
• aggregate the expression value for each pixel of the second physiology measurement into a plant index, the plant index representing the effect of the plant treatment;
• identify, using the plant index, the change in the expressed phenotype induced by the effect of the plant treatment.

A non-transitory, computer-readable medium comprising computer-executable instructions that, when executed by a processor, cause the processor to:

• capture, by a sensor mounted to a vehicle traversing through a field, a first physiology measurement for a plant in the field at a first time, the first physiology measurement comprising a plurality of pixels representing an expressed phenotype of the plant before a plant treatment;
• capture a second physiology measurement for the plant in the field at a second time, the second physiology measurement comprising pixels representing the expressed phenotype of the plant after the plant treatment;
• for each pixel of the second physiology measurement, determine an expression value quantifying a difference between the first physiology measurement and the second physiology measurement, the difference representing a change in the expressed phenotype induced by an effect of the plant treatment;
• aggregate the expression value for each pixel of the second physiology measurement into a plant index, the plant index representing the effect of the plant treatment on the expressed phenotype;
• identify, using the plant index, the change in the expressed phenotype induced by the effect of the plant treatment.
