| 摘 要： | 针对中华结缕草深休眠的特性,研究了不同物理、化学等处理方法对中华结缕草解除休眠的作用。结果表明:以700mL·L-1乙醇浸泡3min后,在300g·L-1NaOH溶液中处理20min,再用200mg·L-1GA3浸泡10min效果最好,7d发芽势达89 9%,比对照高出51 9%;16d发芽率达91 0%,比对照高出51 8%,已接近中华结缕草种子的潜在发芽率,发芽历时比对照缩短12d。

| Abstract: | According to the characteristics of Zoysia sinica seeds, different treatments were arranged to break the seeds deep dormancy. The result showed that the seeds germinated well when they were treated with 700 (mL·L-1) alcohol for 3 min, with 300 mg·L-1 NaOH for 20 min and with 200 mg·L-1 GA3 for 10 min sequentially,the germination potential was 89.9% in 7 days, which was 51.9% higher than that of the control.In 16 days,91.0% of seeds could germinate, nearing the potential germination rate, which was 51.8% higher than the control. |
