摘要：

以当年采收（优质）和自然储藏1年（劣质）的一串红种子为材料, 用不同浓度PEG、KNO3 、PEG+KNO3对一串红种子进行引发效果研究，结果表明：1.0% PEG处理12h可以提高优劣种子的发芽率为16.7%, 2.5% KNO3 处理12h提高的发芽率分别为20%，26.7%，1.0% PEG+2.5% KNO3处理优劣种子12h发芽率分别可以提高23.3%，26.7%。

Abstract:

Seed with two different vigor level of Salvia splendens were treated by PEG, KNO3, PEG+KNO3 at different concentrations. The results showed that (1)After treated by 1.0% PEG for 12h the germination percentage were both increased by 16.7. (2)After treated for 12h with 2.5% KNO3 in High-quality seed and Poor-quality seed, the germination percentage were increased by 20,26.7 separately. (3)The best priming effect was obtained at the treatment of 1.0% PEG+2.5% KNO3,soaking 12h, The germination percentage of High-quality seed and Poor-quality seed was raised from 50.0% to 73.3% and from 26.7% to 53.4% respectively after priming.
