Physical properties of CM and PM discs excised and isolated from mature ‘Karmijn de Sonnaville’ apples and ‘Conference’ pears. Biaxial strain release was calculated as a fractional (%) decrease in the area of the CM and PM upon excision and enzymatic isolation.

Specimen	Mass (g m−2)		Strain (%)
	Apple	Pear	Apple	Pear
CM	23.7 ± 0.4a*	17.3 ± 0.4a	5.7 ± 0.4b	7.6 ± 0.5b
PM	17.4 ± 0.4b	11.7 ± 0.2b	11.0 ± 0.6a	21.8 ± 1.1a

*Data are the means and standard errors of five replicates (comprising six CM or PM discs each) for mass and of 30 replicates for strain.

Mean separation within species by Tukey's Studentized range test, P < 0.05.
