| In order to provide the data support for germination physiology, the dynamic change of germination character and fat, fatty acid and lipoxygenase of Allium mongolicum Regel seeds during germination were observed. The results showed that: except the dry weight of seedling, germination rate, length of seedling and root and fresh weight of seedling increased with days prolonged; the content of fat increased at the early stage and decreased at the later stage, was 1.55% at sixth day and was lower than at other days. The content of linoleic acid was the highest, was 62.73%~72.57%, and the oleic acid was second in all the fatty acid. There were significant negative correlations between saturated fatty acid and unsaturated fatty acid of the seeds during germination. The activity of lipoxygenase reached the maximum within 4 days, but reduced with the content of linoleic acid and linolenic acid decreased at 4 days later during the germination. |
