摘　　要：研究不同浓度赤霉素浸种对中国石蒜种子发芽率、发芽势及发芽时间的影响。结果表明:GA3能促进中国石蒜种子的萌发;经0.3g/L的赤霉素溶液浸泡后的种子的发芽率为98%、发芽势为81%、发芽时间比对照相比提前28d。Different concentrations of gibberellin were used to treat with the seeds of Lycoris chinensis, germination rate, germination energy and germination index were studied. The results showed that gibberellin could improve the Lycorischinensis seeds germination. When the density was O. 3 g/L, the germination rate was 98 %, germination energy was 81%, and germination times were 28 days earlier than the control.
