Abstract A pot experiment was conducted to study the seedling emergence of weedy rice in Northern China at different sowing depths.Results showed that the elongation of mesocotyl and internode of coleoptile played important roles in the seedling emergence of the weedy rice from northern China.The mesocotyl of weedy rice elongated at 3 cm sowing depth,but both the mesocotyl and the coleptile elongated at 5 cm sowing depths.The germination dynamics of weedy rice at deep sowing depth depended on the elongation of mesocotyl and coleoptile.
