Inner Quality: Influence and Assessment in the Case of Selected Ornamental Plants

The goal of the plant grower is a continuous improvement of the quality of ornamental plants. Therefore, an unambiguous and objective assessment of quality is needed. In order to investigate this problem, some ornamental plants (this paper is focused on the example of Euphorbia pulcherrima) were selected after variable growth to compare the parameters of biophotonics with the results of conventional shelf-life tests. It turned out that biophotonics was valuable in determining the potential shelf-life of the plants after harvest, preferably by taking the leaves as subjects of investigation and by following well-defined measuring protocols.
