  • SOFT LEAF TISSUE ELASTICITY TESTER AND USE THEREOF FOR MEASURING PLANT HEALTH
    Publication number: 20240361291
    Abstract: Described herein is a soft leaf tissue elasticity tester comprising a modified piezoelectric finger (PEF) sensor and a sample pad useful for rapidly and sensitively screening plants for disease by quantifying changes in tissue elasticity and/or stiffness as an indication of plant disease. Also described is a method of screening plants for disease by quantifying changes in tissue elasticity and/or stiffness as an indication of infection. The tissue elasticity measurements used to screen plants for disease may be performed using the soft tissue elasticity tester described.
