Canopy architecture and radiation interception measurements in olive
Description
In this work we tested techniques suitable for a future validation of the RATP
model to simulate transpiration and photosynthesis of mature olive trees under field
conditions. Canopy architecture was characterised with an electromagnetic 3D
digitiser and the software 3A. Although the capability of the software to deal with
big data sets has to be improved, the system seems to meet the RATP requirements.
An array of radiation sensors mounted in an aluminium bar and located at different
positions within the canopy showed to be an useful tool for monitoring radiation
distribution; these data can be used to validate the RATP predictions. Leaves
intercepting more radiation showed greater values both of area based nitrogen
content and photosynthetic capacity, and the increment of nitrogen was found to be
related to the increment in leaf mass area. A method was tested for assessing plant
leaf area, which could allow us to determine the leaf area of the biggest trees in the
orchard, with reduced time and labour.
