[Effects of seed priming on vigor of Prunella vulgaris seeds].
OBJECTIVE
To select an effective way to enhance vigor of Prunella vulgaris seeds.


METHODS
Three population seeds were treated at the 20 degrees C and dark enviroment.


RESULTS
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.


CONCLUSIONS
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.
