Mechanical properties of 4-d-old hypocotyls

Mechanical parameters were obtained for Col-0 and mur10 hypocotyls. Significant differences were obtained in tensile strength and diameter (average of 20 samples ± sd).

	Col-0	mur10-1	Dunnett's Test
Tensile modulus	19.54 ± 5.40 MPa	17.94 ± 3.71 MPa	Not significant
Tensile strength	1.286 ± 0.215 MPa	1.119 ± 0.197 MPa	P < 0.05
Failure strain	0.129 ± 0.029	0.115 ± 0.031	Not significant
Diameter	0.253 ± 0.020 mm	0.284 ± 0.017 mm	P < 0.001
