- 摘要:
- 为比较不同浓度浸种溶液处理对大葱种子萌发特性的影响,以大葱种子为试材,采用3种不同浓度的ACC、GA、CaCl2溶液进行浸种处理,测定大葱种子发芽指标的变化。结果表明:3种外源处理都有助于提高种子的活力水平,加快发芽速度。经3种不同浓度的试剂浸种处理之后,种子的发芽率、发芽势和发芽指数均优于对照组;ACC、GA和CaCl2溶液促进种子发芽的最佳浓度分别为20 μmol?L-1,200 μmol?L-1和10 mmol?L-1,综合比较认为20 μmol?L-1的ACC浸种处理对促进种子发芽的效果最为显著。
- Abstract:
- In order to compare the effects of seed soaking solution on the germinationof green onion seeds,the index of seed germination index of green onion were compared in different concentrations of ACC,GA and CaCl2 solutions treatments in this paper.The results showed that three kinds of seed soaking solutionsall could improve the level of seed vigor,and speed up the germination.The seed germination rate,germination energy and germination index were higher than that of CK,and the suitable concentration of ACC,GA and CaCl2 was 20 μmol?L-1,200 μmol?L-1and 10 mmol?L-1,respectively.The ACC seed soaking of 20 μmol?L-1had the most significant effect on promoting seed germination of green onion.
