The elastic modulus for maize stems

Table 2 Repeatability statistics obtained from repeated tests of prepared specimens: 10 stalk specimens, 10 internodal specimens, and 10 tensile specimens

Test type	Specimens description	Tissues tested	% Repeatability (Mean ± SD)	95% Successive tests confidence interval upper bound (%)	n
Bending	Stalks	Multiple	1.5 ± 0.9	3.7	10
Compression (overall)	Node–node	Multiple	3.8 ± 3.7	11.0	9^a
Compression (local)	Node–node	Single	3.9 ± 2.7	9.2	9^a
Tensile	Rind strips	Single	1.9 ± 1.3	4.9	10

Five tests were performed on each specimen to obtain a single reliability value, defined as the standard deviation of the resulting modulus of elasticity values
^aOne sample was damaged during testing and therefore was excluded
