摘    要:目的:探讨提高夏枯草种子活力的有效途径。方法:20℃、黑暗条件下,采用一定浓度的液体引发剂对3个居群夏枯草种子进行引发处理。结果:20%~30%聚乙二醇(PEG),200~400mg·L-1赤霉素(GA3)引发促进夏枯草种子萌发,种子活力提高;0.6%~3.0%NaCl引发,夏枯草种子发芽率降低,发芽时间不同程度提前。0.6%~2.4%KNO3-KH2PO4引发,促进紫金山、磐安夏枯草种子萌发,亳州夏枯草种子发芽率降低。结论:适量浓度PEG,GA3提高夏枯草种子活力,KNO3-KH2PO4,NaCl降低低活力夏枯草种子的发芽率。

关 键 词:夏枯草种子  发芽  活力  种子引发

Abstract:OBJECTIVE: To select an effective way to enhance vigor of Prunella vulgaris seeds. METHOD: Three population seeds were treated at the 20 degrees C and dark enviroment. RESULT: Priming with 20% - 30% PEG and 200 - 400 mg x L(-1) GA3 could enhance seeds germination and vigor. Germination percentage of three population seeds treated with 0. 6% - 3.0% NaCl reduced, but they started to germinate in advance. Treated with 0.6% - 2.4% KNO3-KH2PO4, germination rate and vigor of seeds in Zijinshan and Pan' an both increased and the one in Bozhou decreased. CONCLUSION: Vigor of P. vulgaris seed treated with PEG and GA3 under proper concentration increases, while treated with KNO3-KH2PO, and NaCl low vigor seeds germination rate reduces.
Keywords:the seed of Prunella vulgaris  germination  vigor  seed priming
