不同处理方法对苦参种子发芽特性的影响

采用不同方法对苦参种子进行处理,并对处理后种子的发芽势和发芽率进行了统计分析.结果表明:浓硫酸(98%)处理、沙磨处理和烫种均可以明显提高苦参种子的发芽势和发芽率,其中浓硫酸处理20 min为最佳处理,发芽势和发芽率分别达到82.0%8、6.7%;其次为沙磨处理,发芽势和发芽率分别达到49.3%、72.7%.高锰酸钾和赤霉素处理对苦参种子的发芽有一定的促进作用,但效果不显著.硝酸钾处理抑制了苦参种子的萌发.

Effect of different treatment methods on seed germination characteristics of Sophora flavescens

After processing seeds of Sophora flavescens with different treatment methods the germination potential and germination rate was statistically analyzed.The results indicated that the seed treated with 98 % H2SO4,grinding with sand and scalding with boiling water obviously improved the germination potential and germination rate,when treatment with 98 % H2SO4 for 20 minutes showed the best result,with 82.0 % of germination potential and 86.7 % of germination rate.The grinding with sand also increased 49.3 % of germination potential and 72.7 % of germination rate.The treatment with KMnO4 and GA3 had a certain effect on germination;however,no significant difference was found.KNO3 treatment restrained the germination.
