摘要：目的:研究不同含水量当归种子贮藏过程中的生理生化特性。方法:每隔2月测定种子发芽率、发芽指数、相对电导率、超氧物歧化酶(SOD)活性、可溶性糖及蛋白质含量的动态变化。结果:在15℃条件下密闭贮藏10月,含水量为2.85%的当归种子能保持85%以上的发芽率;随着含水量降低,种子浸出液相对电导率增幅减小,SOD活性和蛋白质含量下降趋势变小,可溶性糖含量变化较为稳定。结论:在阴凉条件下,适度降低含水量能延长当归种子的贮藏寿命,而增加含水量会加速其种子的劣变进程。
Objective:To study the physiological and biochemical changes during storage of angelica seeds with different moisture contents.Method:The dynamic changes of percentage and index of seeds germination,relative conductivity,superoxide dismutase(SOD) activity,contents of soluble sugar and protein were determined at an interval of every two months.Result:Under the conditions stored in sealed paper cups at 15 ℃ for 10 months,the germination percentage of angelica seeds with 2.85% of moisture content was kept above 85%.With moisture content reducing,the increase rate of relative conductivity decreased,the down trend of SOD activity and protein content were weakened,and soluble sugar content kept stable.Conclusion:In cool conditions,a modest low moisture content of seeds can be beneficial to prolong the longevity of angelica seeds,while high moisture content will accelerate the deterioration process of the seeds.
