Phenomics is a new omics and recently attracts many interests from those who are working on genomics and crop breeding. A core element of phenomics is non-destructive and rapid diagnosis of plant phenome. One major technology for phenomics is spectral image analysis of reflected light from plants. This spectral image analysis of weeds after herbicide treatment may be used for herbicide screening as a part of high throuput screening (HTS). Therefore, this study was conducted to develop rapid bioassay method using plant spectral image analysis. Herbicides were sprayed to Echinochloa species in arange of doses. Leaf chlorophyll fluorescence and leaf thermal image were measured using a chlorophyll fluorimeter and an infra red camera, respectively, and the images were analyzed. Leaf chlorophyll fluorescence and leaf temperature behaved with increasing herbicide dose. Therefore, in this presentation, we will present the potential application of spectral image analysis to herbicide bioassay.
