Chapter 7. Spectral radiometry
Mullan, D.J.
Chapter 7. Spectral radiometry - Mexico, D.F. : CIMMYT, 2012.
Through a detailed understanding of the electromagnetic spectrum and the optical properties of plant canopies, researchers have been able to take a large leap forward in the efficiency of screening physiological traits. These technologies are now able to identify the very best genotypes from early generation material, before expensive yield trials are conducted, and enhance selection from already superior advanced lines. This chapter outlines the theoretical framework behind spectroradiometry and the important considerations that should be understood when performing remote sensing measurements and interpreting spectral results. It also details spectral reflectance indices, which relate to various aspects of plant physiology, such as vegetative growth, water status and photochemistry. Spectroradiometry is a powerful selection tool that lends itself to the high-throughput screening of traits. It has the potential to enhance future genetic gains, increase wheat yield potential and improve the response of crops to stress
