Growth stimulation measured by PhenoLab using Multispectral Imaging

Growth stimulation measured by PhenoLab using Multispectral Imaging


This article explores how multispectral imaging and fluorescence imaging assist the PhenoLab. Videometer helps with a study on the improvement of water-use efficiency.

Why water efficiency is important?

Water scarcity is a threat in many places around the world. One of the reasons for it is climate change and an increasing population. To improve this situation, water efficiency and optimizing water usage are implemented in many areas.

By 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world’s population could be living under water-stressed conditions. (un.org)

How can multispectral imaging improve water-use efficiency?

One of the ways to solve water scarcity is optimizing water usage. The water-use efficiency looks at how water is used in plant metabolism. Consequently, it compares water lost in plants through transpiration.

A new scientific paper investigates water use efficiency. It explores growth stimulation in normal and drought conditions.

PhenoLab and Videometer collaboration

The PhenoLab system at the University of Copenhagen, Tåstrup, is used for high-throughput phenotyping. PhenoLab imaging is based on the VideometerLine vision system solution. The VideometerLine includes

  • The VideometerLab functionality
  • spectral reflectance imaging
  • spectral fluorescence imaging

This collaboration results in automated, faster, and more accurate analysis.

The University of Copenhagen has four phenotyping platforms from Videometer at the Tåstrup site:

  • a VideometerLab for laboratory measurements
  • a PhenoLab for high-throughput phenotyping in the greenhouse (used in this paper)
  • a PhenoField for ground-truthing on 1 meter by 1 meter plots in the field
  • a Radimax for rhizosphere imaging using multispectral mini-rhizotrons

Videometer technology presented and explained in the scientific article

The paper explores how water use efficiency via growth stimulation can enhance the growth of plants. The example follows maize (Zea mays L. cv. Ronaldinho) and analyses plant growth-promoting rhizobacteria (PGPR). It focuses on both normal and drought conditions.
