Light transmittance and sunlit leaf area estimation in a peach canopy

A preliminary analysis was performed to evaluate the structural differences in the different parts of a representative peach tree trained to palmette. The shoot inclination angles showed a spherical and planophile distribution at the top and at the bottom, respectively. The measured canopy transmitt...

Description
Summary:A preliminary analysis was performed to evaluate the structural differences in the different parts of a representative peach tree trained to palmette. The shoot inclination angles showed a spherical and planophile distribution at the top and at the bottom, respectively. The measured canopy transmittance was found to depend on the LAI and solar elevation angle. An empirical model, using an extinction coefficient as a function of the solar elevation angle, was tested to determine the light transmittance in a peach orchard. A good agreement was found between the daily means measured and predicted by the model at three heights in the canopy. The model proved to be useful for estimating diurnal and seasonal variation in the total sunlit leaf area.
