Abstract

The photon-counts of wheat seeds germinating in different wastewater sediment solutions are analyzed and correlated with seedling development. It is shown in three different series that the detected light intensity and its increase over time are correlated with the seedling growth. The procedure presented here is based on a very simple photomultiplier tube-based apparatus and constitutes a fast method to evaluate seed germination with real-time response and can help in studies on fertilization evaluation.
