摘　　要：通过对人工去除花药与花冠和人工去除花药留花冠2个处理进行调查，结果显示，芝麻去除花药和花冠后，结蒴率和相对结实率分别为0～10．0％和0～4．0％；去除花药留花冠后，结蒴率和相对结实率分别为14．29％～90．0％和3．18％～55．23％。花冠对芝麻异花传粉具有极其重要的作用，直接体现在有利于传粉昆虫的有效访问上，花冠的存在能够提高芝麻异花传粉的概率，使结蒴率和相对结实率分别增加14．29％～88．57％和2．54％～41．90％。The effects of corolla on insect-mediated cross pollination were studied in sesame.The results showed that the capsule setting rate （CSR） and relative seed setting rate （RSSR） of sesame were respectively 0--10.0 % and 0--4.0 % by means of artificial removing anther and corolla.After removing anther but existing corolla,the CSR and RSSR of sesame were 14.29%-90.0 % and 3.18%--55.23%, respectively.Therefore, corolla had the extremely vital role on sesame eross-pollination. Corolla was beneficial to insect effective visiting in the proeess of pollination, and increased sesame cross-pollina- tion probability,resulting that the CSR and RSSR of sesame increased 14.29 %--88.57% and 2.54%- 41.90 %, respectively.
