[Effects of seed priming on salt tolerance in Prunella vulgaris seed germination under saline conditions].
Zhongguo Zhong Yao za Zhi = Zhongguo Zhongyao Zazhi = China Journal of Chinese Materia Medica 2009 April
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.
