[Effect of storage methods on breaking seed dormancy of Trollius chinensis Bge]
1Institute of Medicinal Plants, CAMS and Peking Union Medical College, Beijing 100094, China.
Objective:
Exploring the best seed storage method for Trollius chinensis.
Method:
Different temperatures were applied to the seed storage in wet sand and dry sand, and the embryo-endosperm ratio and germination rate were inspected.
Result:
The dormancy of T. chinensis seeds could only be broken in lower temperatures. The newly collected seeds set out to germinate after 75 days of storage at 5-6 degrees C when the embryo-endosperm ratio reached 47%, and the time of seed germination varied with the length of storage time before low-temperature treatment.
Conclusion:
The best storage method for the seed of T. chinensis is keeping it in dry for 6-8 months with an additional 1 month of low-temperature treatment to follow.
