FIGURE 1.

Plant Stiffness Changes with Time of Day and Developmental Stage. CML258 plants were tested at tasseling VT (103 days) and dent R5 (128 days) stages from two replicates (Plot A and B). At VT, within replicate A, each plant was tested three times as indicated by the colored dots (blue—first, red—second, and black—third tests). The Force‐Deformation slope is reduced throughout the day (p = 2.36E⁻⁰⁶). The effect of replication and repeat testing was not significant (p = .716 and .972, respectively). The same plants were tested at R5 and show higher Force‐Deflection slope compared to any time point at VT. Plant 11 and 12 in replicate A at R5 were not used due to weed control damage
