Project code: JKI-PB-08-1177
Contract period: 01.09.2010 - 30.11.2014
Purpose of research: Applied research

The aim of the project is to quantify the water status of biogas rye based on optoelectronic methods (reflection spectroscopy, infrared camera, infrared thermometer) to judge the drought tolerance. The project especially contributes to the the main target 2 ('developing the potential of renewable resources') of the research plan of the Federal Ministry of Food, Agriculture, and Consumer Protection (BMELV). Because renewable energy sources are largely CO2-neutral and represent an alternative source of income for people in rural areas, the project also contributes towards the BMELV main target 3 ('Perspektives for rural areas') and main target 4 ('Climate protection and adaptation to climate change').

The currently ongoing climate change will even in the temperate zone of Central Europe expose the agricultural crops to an increasing aridity during the main growing season. It is therefore important to provide drought-tolerant cultivars for agriculture. In the present project it was examined whether the drought tolerance of rye genotypes can be assessed using infrared thermometry and reflectance spectrometry. The project is thus directly related to cli-mate adaptation in agricultural production as a main research objective of the JKI. Three-year drought stress experiments in rain-out shelters at the JKI in Braunschweig (working group Schittenhelm) as well as at selection sites of the KWS LOCHOW GmbH (working group Lilienthal) have shown that both the canopy temperature (or its reduction relative to the ambient temperature) and spectral reflectance indices represent useful secondary traits for the evaluation of drought tolerance. By means of these methods large plot trials with thousands of genotypes can be assess contact-free, quickly and relatively inexpensively. Compared to the canopy reflection, the measurement of the canopy temperature has the disadvantage that it is heavily weather-dependent. Useful measurement data can be only obtained on days with clear skies (global radiation >700 W/m2), high air temperatures (>20 °C) and low wind speed (
