Seed retention of Angelica sinensis

Seedling transplanting requires the use of moderately mature seeds from flowering in the third year. A plant has many lateral buds in addition to the main buds. Both main buds and lateral buds can bolt, blossom and bear fruit. Flower branches and seeds can also grow in the armpits of the main stem. Due to the different growth time of each flower branch, the flowering time and seed maturity are first and later. Therefore, when collecting seeds, we must often go to the field for observation. Looking down from the top of the flower stem, we can see that the first ear is pink, the second ear is light red, and the third ear is light yellow, which needs to be harvested (usually in the first and middle of August). Overmature seeds, seedling transplanting, will bolting early, so it is best in the seed medium well, fold off the ear, insert in water or wet soil, or rolled in Artemisia annua, after 12 to 48 hours, see white has completed the post-ripening effect. Tie the harvested ear into small handfuls, hang the stalk with branches in a smokeless, dry and ventilated place, make it fully dry (water content less than 8%), then remove impurities, seal and store in a dry and cool place. Avoid exposure, baking and rain.

Direct seeding cultivation must select biennial seeds with high maturity and full grains. Direct seeding with such seeds will result in early emergence, vigorous seedling growth and rapid growth, which is an important factor to obtain high yield. However, such seeds are only suitable for direct seeding and cannot be used for seedling breeding.
