| 摘 要： | HCl、NaOH、Na2CO3、NaCl、赤霉素（GA3）、芸薹素内酯（BR）浸种处理，探讨溶液浓度、浸种时间对野慈姑（Sagittaria trifolia Linn．）种子萌发的影响。结果表明，NaOH溶液浸种处理可以作为快速解除野慈姑种子休眠、提高发芽率的方法，最佳处理为25％NaOH溶液浸种4h，可使野慈姑种子萌发率达73．00％。HCl溶液浸种处理仅能解除部分野慈姑种子的休眠，20％HCl溶液浸种4h野慈姑种子的发芽率最高；为48．33％。Na2CO3、NaCl、GA3、BR溶液浸种处理，野慈姑种子的最高发芽率分别仅为10．33％、9．33％、11．33％、9．67％，不能用于解除野慈姑种子的休眠。

| Abstract: | The effect of solution concentration of HCl, NaOH, Na2CO3, NaCl, gibberellic acid （GA3 ） and brassinolide （BR） and seed soaking time on the germination of Sagittaria trifolia was studied. Soaking the seeds in 25% NaOH for four hours was the fastest method to break dormancy and increase germination rate to 73%. Soaking in 20% HCl also for four hours partly broke dormancy and improved germination to 48%. The highest S. trifolia germination rate obtained by soaking the seed in GA3, Na2 CO3, BR, and NaCl was 11%, 10%, 10%, and 9% respectively, but these chemicals were not suitable for breaking dormancy. |
