Leaf area distribution measurements in solitary growing old olive trees

Irrespectively of long-term growing of olive trees in Mediterranean countries, little is known about leaf distribution in old solitary growing trees in the orchards. Leaf area distribution was estimated using a combination of two approaches: a simple composite geometrical canopy-layer model and ground-based side images evaluated by the image analysis software. This distribution was evaluated separately in a vertical direction, which is particularly important for physiological studies and in a radial direction, which is important for interpretation of remotely sensing images
