Method for germinating Polygonatum sibiricum seeds

1. Seed collection and cleaning

The seeds of Polygonatum sibiricum generally mature from September to November, at which time they are picked and soaked in water. Removing the outer skin of the seeds by scrubbing will help increase germination rates. Do not damage the seeds when washing, then filter out the skin and impurities and take out the seeds.

2. Post-ripening

Place the Polygonatum sibiricum seeds in an incubator and spray them with the after-ripening solution. The humidity in the incubator should be high and not too dry. Then, irradiate with ultraviolet light for 20 minutes, take out and let it stand for 1 hour. Soak it in water at 20°C and take it out after 4 days.

3. Shade Drying

The late-ripening seeds cannot be placed in the sun to dry, otherwise it will easily lose moisture and reduce its germination rate. You need to put it in a cool place and wait for it to dry. You can also put it in a freeze dryer to speed up the germination of seeds.

4. Germination in sand

Bury the treated seeds in wet sand and take them out after 100-150 days. At this time, the seed germination rate can reach 80%, and the germination time can be shortened, and it can grow in about a month.
