摘要
在恒温条件下(24℃),利用不同浓度的赤霉素、硝酸钾、双氧水对经过不同层积天数的栾树种子进行浸种催芽试验。结果表明:以0.3%的硝酸钾溶液浸泡层积了50 d的种子,其发芽率最高,可达到91.0%;其次为900 mg/L的赤霉素溶液浸泡层积时间为50 d的种子,发芽率也达到86%。与对照相比,差异显著。
Under constant temperature（24℃）, the seeds of Koelreuteria paniculata were treated by different concentrations of gibberelin, potassium nitrate, hydrogen peroxidesolution and chilled with different days, respectively. The results showed that compared with the control, 0. 3% potassium nitrate and stratificated 50 days was the best handle combination of germination in Koelreuteria paniculata. The average germination rate could get up to 91.0%. 900 mg/L GA and stratificated 50 days was the better treatment.
