Two Case Studies of Precision Horticulture Approaches in Citrus Production

摘要

In the age of information technology, process-oriented data analysis is the focus of emerging science and is predicted to form the basis for economic growth. The general consensus is that, especially in agronomy, new innovative approaches are needed for a future process management. Because citrus is economically a very important fruit crop worldwide, two case studies of in-situ analysis of plant and fruit with prominent importance in the citrus production are reviewed targeting site-specific production measures. In the first approach, the review provides a background of the measurable plant response to oxygen shortage in the root zone by means of non-destructive methods and gives an outlook of the applications in citrus. In a second case study the quality analysis of citrus fruit at the tree level is discussed. The feasibility of the spatio-temporally resolved data recording in the harvest management is pointed out.
