【 摘 要 】

The chlorophyll fluorescence measurement to diagnose herbicide resistant Echinochloa species at the reproductive (late) growth stage was applied. The significant correlation between F_v/F_m (chlorophyll fluorescence measurements) and fresh weight (whole plant test) and the statistical similarity of R/S ratios between the two tests demonstrated that the chlorophyll fluorescence test could be reliably used to diagnose herbicide resistant Echinochloa spp. at the reproductive growth stage in a shorter period of time (within 10 days) compared with the conventional whole plant test.
