激动素丙酮溶液处理的龙胆种子经过一定天数的人工老化后,其发芽率、发芽指数、活力指数均较不处理的和用水作对照的种子高,其中100μM、50μM激动素丙酮溶液效果最明显。处理1小时的种子发芽率和活力指数比处理2小时的高。随着老化天数的增加外渗液电导率和电解质外渗百分率均增大,但处理与不处理间的电导率和电解质外渗百分率差异不大。
After a certain number of days of artificial aging, the gentian seeds treated with kinetin acetone solution had higher germination rate, germination index, and vigor index than untreated seeds treated with water, of which 100 μM and 50 μM kinetin acetone solution had the most obvious effects. . The germination rate and vigor index of seed treated for 1 hour were higher than those treated for 2 hours. With the increase of aging days, the conductivity of extravasation and the percentage of extravasation of electrolyte increased, but there was no significant difference in the percentage of conductivity and electrolyte extravasation between treated and untreated.
