ABSTRACT
<p><b>OBJECTIVE</b>To study the physiological and biochemical changes during storage of angelica seeds with different moisture contents.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>Under the conditions stored in sealed paper cups at 15 degrees C 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.</p><p><b>CONCLUSION</b>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.</p>
