Influence of drought on leaf cuticle thickness

	Cuticle thickness (μm)
Treatment	IAPAR59	Rubi
Control	1.49 ± 0.19(a)	1.75 ± 0.15(b)
Drought	1.98 ± 0.19(c)	1.73 ± 0.28(b)

Leaves of IAPAR59 and Rubi cultivars of C. arabica grown under control (irrigation) and drought conditions were analysed to measure the cuticle thickness of the abaxial faces. Values (in μm) correspond to the average calculated from 11 independent measurements. Those marked with different letters are significantly different (Student-Newman-Keuls mean comparison test, P < 0.05)
