Cinnamomum kanehirae Hay. is an unique specie in Taiwan. The trees are sturdy and huge, so people in Taiwan call it “Niu-Chang”
means that the tree is growing as strong as a bull. It is difficult for the sticky entomophilous flowers of Cinnamomum kanehirae
Hay. to pollinate among female trees. Especially, the flowers grow on the top crown of the tree where the wind blows them
away. Sometimes, the seeds are eaten by birds and animals before maturity so that seed collecting is challenging.Even some
seeds are survived in the natural environment, they died because of the insufficient light in the woods, the thick leaves block the
bedding on the ground, and so on. It is hard to be reproduced by seeds. Therefore the research on asexual reproducing has been
taken by Taiwan Forestry Research Institute a decade ago.Now they found grafting technique is proved to be successful and the
plantlet of Cinnamomum kanehirae Hay. can be mass produced.
