[Effect of storage methods on breaking seed dormancy of Trollius chinensis Bge].
OBJECTIVE
Exploring the best seed storage method for Trollius chinensis.


METHODS
Different temperatures were applied to the seed storage in wet sand and dry sand, and the embryo-endosperm ratio and germination rate were inspected.


RESULTS
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.


CONCLUSIONS
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.
