| 目的: 提高防风种子发芽率, 加大黑龙江省地道药材防风的开发力度。方法: 分别采用45?? 温水浸种12~ 24h; 150w
微波辐射15s、2 0s、25s 30s; 流水冲洗防风种子3~ 4h; 柳枝浸出液为萌发剂培养防风种子, 同时培养未经处理的种子作为对照组。
结果: 对照组发芽率为36. 67%; 温浸组为60. 33%; 微波15s 组发芽率为68. 00%, 20s 组为74. 33%, 25s 组为71. 17%, 30s 组为67.
33%; 流水组发芽率为84. 00%; 柳枝组发芽率为68. 67%。结论: 大规模播种可采用45 ?? 温水浸种12~ 24h、150w 微波辐射20s、流
水冲洗3~ 4h、柳枝浸出液为萌发剂均可提高发芽势、发芽率, 缩短发芽历期, 改善出芽不齐等现象。 |

| Objective: To improve the germination rate( GR) of Saposhnikovia Divaricata ( Turcz. ) Schischk seeds. Methods:
Soak the seeds in warm water( 45 ?? ) ( 12~ 24h) ( group 1) ; radiatewith microwave( 150w) for 15s, 20s, 25s, 30s respectively( group 2) ; rinse
the seeds with running water ( 3~ 4h) ( group 3) ; soak the seeds with the lix ivium of willow branch( group 4) , at the same time, the unsettled
seeds are treated as contrast( group 5) . Results: The GR of group 5 is 36. 67%; group 1 60. 33%; group 2 68. 00%( 15s) , 74. 33%( 20s) ,
71. 17%( 25s) , 67. 33%( 30s) respectively; group 3 84. 00%; group 4 68. 67%. Conclusion: For large- scale sowing, the following meth??
ods can be used: soaking the seeds in warm water( 450C) for 12- 24 hours, radiating the seeds with microwave( 150w) for 20s, rinsing the seeds
with running water for 3- 4h, and soaking the seeds with the lixivium of willow branches, which can increase vigour of germination and germina??
tion rate and improve the sprouting of the seeds. |
