摘要
采用了多因子变量的方法,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和不同处理时间对一串红种子进行引发效果研究,旨在提高一串红种子的发芽率。结果表明:(1)1.0%PEG处理12h可以提高优劣种子的发芽率约为16.7%;(2)2.5%KNO3处理12h提高的发芽率分别为20%,26.7%;(3)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%.
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.
