Research on propagation techniques of Cinnamomum balansae Lecomte from seeds

Abstract

The results of the study on the characteristics of the fruit, seeds and
propagation Cinnamomum balansaeby seeds at the Forest Science Centre
for Central of North Vietnam showed that, fruit of C.balansaeis small size,
on average, there are about 2,279 fruits/kg. Each fruit contains 1 seed, the
weight of 1,000 seeds ranges from 0.35 to 0.38 kg, equivalent to 2,632 -
2,857 seeds/kg, an average of 2,778 seeds/kg. The seed purity of the
provenances ranged from 80.7 - 85.2% with an average of 83.4%. Testing
of preserving seeds of C.balansae according to different experiments has
shown that C.balansae seed is suitable for store in a refrigerator at a
temperature of 5
o
C, after 2 months of storage, the survival rate of seeds are
62.0%. C.balansae seeds germinate best when soaked in warm water at
30
o
C for 4 - 6 hours, for the germination rate of 83.0 - 85.0%. The potting
medium suitable for seedlings for nursery is 98% of soil + 2% of NPK
fertilizer (16: 16: 8), after 6 months the growth of C.balansaeseedlings are
the best, reaching the survival rate is 87.8%, the root diameter is 0.56 cm
and height is 50.4 cm
