[Effects of seed priming on salt tolerance in Prunella vulgaris seed germination under saline conditions].

Abstract

OBJECTIVE Selecting an effective way to increase salt-resistance of Prunella vulgaris seed through seed priming technology. METHOD 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. RESULT 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. CONCLUSION Treated with PEG, GA3, KNO3-KH2PO4 under proper concentration, the seed vigor, seed resistance under salt stress increased.
