摘要： 在甘蔗下种前，用不同浓度的乙烯利浸种处理，结果表明：50mg/L、100 mg/L、200 mg/L浓度的乙烯利浸种对甘蔗的萌芽、分蘖都有影响，特别是在干旱条件下，乙烯利浸种甘蔗的出苗速率和分蘖率比对照好，并改善了甘蔗的农艺性状和品质。

Abstract: Seed-canes of sugarcane were soaked with different concentrations of ethephon before planting. The results showed that the treatments with ethephon concentrations of 50mg/L, 100 mg/L and 200 mg/L markedly affected the germination and tillering of sugarcane. Under drought conditions, the seed-cane soaking treatments with ethephon recorded higher germination rate and tillering rate, and improved agronomic characters and the cane quality as compared with the control.
