Open Access Publication of the Month – Erekle Chakhvashvili (IBG-2) et al.

4 December 2024

To encourage us all to broaden our horizons, each month the Central Library selects one open access publication from the JuSER publications portal to be featured in the newsletter of Forschungszentrum Jülich.

In the open access publication of the month, Erekle Chakhvashvili, Lina Stausberg, Juliane Bendig, Lasse Klingbeil, Bastian Siegmann, Onno Muller, Heiner Kuhlmann, and Uwe Rascher from IBG-2 and the University of Bonn write about the drought-induced leaf movement of soybean crop and the detection of this movement through various remote sensing tools.

Drought is one of the major environmental stressors that threatens agricultural productivity, and its frequency and severity is expected to increase with the changing climate. Plants have evolved various mechanisms to mitigate drought effects. One such mechanism is paraheliotropism, a type of leaf movement that helps plants avoid light and serves as an early stress indicator.

This study investigates the combined use of terrestrial laser scanning and drone-based multispectral imaging to detect paraheliotropic movement in two soybean varieties. Results show that both methods effectively track leaf movement throughout the day and reveal distinct response patterns between the varieties. This approach offers a novel method for early crop stress detection.

The open access publication entitled "Multispectral imaging and terrestrial laser scanning for the detection of drought-induced paraheliotropic leaf movement in soybean" was published in the journal International Journal of Applied Earth Observation and Geoinformation.
