A method was developed for the spatial analysis of plant architecture as it relates to the within-plant variation in the physical, chemical, and postharvest characteristics of the fruit. Computer graphics were used to reconstruct the architectural framework and spatial arrangement of the fruit in the canopy of kiwifruit vines (Actinidia deliciosa) trained on two different support structures. An infra-red beam theodolite was used to obtain the spatial coordinates of the vines components. The data files generated by the theodolite were in turn used with software specifically written for the project (MAPIT - Microcomputer Aided Plant Imaging Technology) to provide a 3-dimensional reconstruction of the original vines. Each fruit was colour coded so that extremes in their attributes could be easily identified and accurately located in the canopy of the vine. Patterns were clearly discernible for both the pergola and T-bar trained vines. The heavier fruit were located at the apical ends of the canes, while greater soluble solids concentrations were associated with the smaller fruit located closer to the cordon. These patterns were consistent for all of the vines examined. The use of the theodolite coupled with the computer graphics described in this paper provides a rapid and objective means of accurately describing plant architecture.
