heal.abstract	The aim of this study was to evaluate the water, turgor, osmotic potentials and leaf water content during leaf ontogeny using both the pressure volume and the psychrometric techniques. The symplasmic water fraction of the total water content decreased with leaf age from 78% in immature leaves to 62% in old leaves. The capability for osmoregulation was almost the same in immature and mature leaves but decreased in old leaves. The volumetric modulus of elasticity (ε) was lower in immature leaves (12.7 MPa) and increased in mature (22.5 MPa) and old leaves (28 MPa). The high elasticity of young leaves seems to be an important strategy for adaptation to drought.	en
