The seedling was developed on the dark condition by artificial climate chamber to determine the content of Auxin (IAA), activity of indoleacetic acid oxidase (IAO) and cell wall peroxidase (POD), mesocotyl length change and cell wall oxidase activity variation applied IAA. The study proves that endogenous hormone IAA content of long mesocotyl in weedy rice were much higher than that of short mesocotyl in Akimitsu. With the growth of mesocotyl elongation, endogenous IAA content showed cumulative effects. And then accumulation of IAA content reached up to maximum, when the Mesocotyl elongation stoped to grow. IAA might play a decisive role in the process of hypocotyl elongation. Reduction in the activity of IAO and POD accelerated the transformation from bound IAA to free IAA and promoted cell elongation and mesocotyl elongation.
