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.
目的
筛选出提高夏枯草种子活力的有效方法。
方法
对3个居群的种子在20℃黑暗环境下进行处理。
结果
用20% - 30%聚乙二醇（PEG）和200 - 400毫克/升赤霉素（GA3）引发能提高种子发芽率和活力。用0.6% - 3.0%氯化钠（NaCl）处理后，3个居群种子的发芽率降低，但发芽提前。用0.6% - 2.4%硝酸钾 - 磷酸二氢钾（KNO3 - KH2PO4）处理后，紫金山居群和磐安居群种子的发芽率和活力均提高，亳州居群种子的发芽率和活力降低。
结论
适当浓度的PEG和GA3处理能提高夏枯草种子活力，而KNO3 - KH2PO4和NaCl处理低活力种子会降低发芽率。
