The quality of cuttings is currently being evaluated in young plant production only by external parameters. For direct statements about their inner “fitness”, the metabolic status and their rooting potential suitable diagnostic tools are missing. This obviously complicates an examination of the transferability of interesting fundamental knowledge into practice.

Motivated by this insight, we could show in a previous research project that using near-infrared spectroscopy (NIRS) a fast and non-destructive determination of the nitrogen (N) – and carbohydrate (KH) status of cuttings is feasible and it is possible to derive the rooting potential therefrom.

Near-infrared spectroscopy as part of quality assurance systems in ornamental young plant production - Part of the German Agricultural Innovation Partnership (DIP)

However, actual use of NIRS in practice currently meets some difficulties. The current work has the aim to overcome these obstacles and to establish the determination of the N- and KH status by near-infrared spectroscopy as a routine method for quality control in the young plant companies.

To establish NIRS as an on-site routine procedure benchmarks for the optimum nitrogen and carbohydrate status of ornamental cuttings at harvest will be developed. We also want to better understand the processes in the post-harvest and their impact on the quality of cuttings. We analyze whether and what changes of nitrogen and carbohydrate status after harvest are useful as indicators to identify transport stress, in order to develop approaches for the optimization of the logistics processes.
