Abstract:
Taking 13-year-old ‘Fuji’ trees as test materials，three-dimensional digitizer and Piaf Digit software were used to digitize the large，middle and small canopy of trees trained to tall spindle shape.The tree model and computation of light interception，which was characterized as STAR were realized in the VegeSTAR software.Light transmittance derived from the model had no significant difference from what we measured.The constructed model could be used to assess the light characteristics.The test was to make quantitative and qualitative analysis of the canopy structure.The results showed that the STAR of VL were the largest and the bourse were that of the smallest in five type of shoots；the STAR of fruits related to light interception of bourse，VS，VL and BS.The STAR value could be used as an indicator to assess the canopy light interception，which provided a theory reference for the research on the photosynthetic and pruning and training in the later period.
