摘要
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、20s、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) ; radiate with 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 lixivium 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 largescale sowing, the following methods can be used: soaking the seeds in warm water(450C) for 12 - 24 hours, radiating the seeds with microwave(150w) for 20s, riming 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 germination rate and improve the sprouting of the seeds.
