| Abstract: | The occurrence of weeds in sesame fields in Northeast China was investigated by the five - point sampling method. Sixteen species belonging to 12 families were found. Four species of the Poaceae accounted for 25% of the weeds present and two of the Composite represented 12.5%. Ten families, including Amaranthaceae, Commelinaceae, and Cyperaceae represented by one species each accounted for 6.25% of the weeds. Eighty - one percent of the weeds （ 13 species） were annuals;three perennial grasses accounted for the remaining 19%. |
