| Abstract: |
| In order to understand the biological characteristics of Cinnamomum migao H. W. Li seed，the
basic forms of seed were observed，including morphological characteristics，size，1000-grain weight，etc. Also
seed cleanliness，moisture content，water absorption，seed vigor of different storage methods，germination rate
were determined. The results show that，C. migao H． W．Li seed is brown or reddish-brown and its shape is
spindle，with seed length 0.9-1.5 cm，width 0.8-1.0 cm，thick 0.75-0.95 cm，grain weight is 312.99 g，single
seed weight is 0.32 g，it belongs to large seed，the seed coat is hard and thick. The cleanliness of seed is 97.88%，
the moisture content is 14.1%. Water absorption rate is 33.53%，that is the largest after 36 hours of soaking，but
it is less than 40%，water permeability is poor. About seed vigor，the seed that is just get ten back has high vigor，
seed vigor is 83.3%，with the increase of storage time，seed vigor decreases after stored under three different
methods，the vitality of seed of bag storage fall the fastest，tibetan sand storage is the best way to save C. migao
H. W. Li seed. In conventional germination test of C. migao H. W. Li seed， the germination rate of autumn sowing
is low，only 1.67%，lower than that of spring sowing（38.3%），but on the whole，the seed germination rate
is very low. After treatment of mechanical broken
skin，seed germination rate significantly increases，
with 52%，while the non-treated control is 36%.
Soaking the seeds with concentrated sulfuric acid，the
highest germination rate is 68% after soaking 40 min.
Therefore，the hard seed coat is a limiting factor to
normal germination of C. migao H. W. Li seed. |
