  Plant scientists use Functional Structural Plant Models (FSPMs) to model
plant systems within a limited space-time range. To allow FSPMs to abstract
complex plant systems beyond a single model's limitation, an integration that
compounds different FSPMs could be a possible solution. However, the
integration involves many technical dimensions and a generic software
infrastructure for all integration cases is not possible. In this paper, we
analyze the requirements of the integration with all the technical dimensions.
Instead of an infrastructure, we propose a generic architecture with specific
process-related components as a logical level solution by combining an ETL
(Extract, Transform and Load) based sub architecture and a C/S (Client/Server)
based sub architecture. This allows the integration of different FSP models
hosted on the same and different FSP modeling platforms in a flexible way. We
demonstrate the usability of the architecture by the implementation of a full
infrastructure for the integration of two specific FSPMs, and we illustrate the
effectiveness of the infrastructure by several integrative tests.
