[Effects of seed priming on salt tolerance in Prunella vulgaris seed germination under saline conditions].
OBJECTIVE
Selecting an effective way to increase salt-resistance of Prunella vulgaris seed through seed priming technology.


METHODS
The treatment of salt stress to P. vulgaris seeds was made by the different concentrations of NaCl solutions. Primed seeds germinated under 0.8% NaCl.


RESULTS
As concentrations of NaCl increasing, seed germination percentage, germination index and vitality index reduced. Primed with 15%-35% PEG, 100-500 mg x L(-1) GA3 and 0.4%-2.0% KNO3-KH2PO4 could enhance seeds germination index and vitality index under salt stress while treated with NaCl seeds germination percentage reduced.


CONCLUSIONS
Treated with PEG, GA3, KNO3-KH2PO4 under proper concentration, the seed vigor, seed resistance under salt stress increased.
