Cinnamomum kanehirae Hay. is a native species with great potential for afforestation in Taiwan, and wood of C. kanehirae can be used to cultivate Antrodia cinnamomea. Wild seeds of C. kanehirae, however, are really difficult to collect; besides, such entire research as seed production, seed collection, seed handling, germination methods, and the optimal storage conditions of this species, has been not formally published yet. Thus, it is not workable to satisfy seedling demand and supply by applying appropriate seed storage. Still, the germination technique is not easily available so as to affect the seedling cultivation rate of this species. The goals of this study are: (1) to establish a procedure to produce seeds of C. kanehirae with good quality and quantity, (2) to offer the optimal method of fruit collection and seed handling of C. kanehirae, (3) to give a method for breaking seed dormancy in order to quickly germinate after sowing as well as to decrease the cost of seedling cultivation and increase the seedling cultivation rate of C. kanehirae, (4) to find out the optimal seed storage conditions and estimate the best longevity in order to regulate seedling demand and supply of C. kanehirae, (5) to efficiently establish seedling cultivation system of C. kanehirae, and (6) to compare growth performances of seedlings and cutting propagation of C. kanehirae for afforestation. The primary results of this research shows: (1) seeds of C. kanehirae could be selected by water. The empty and failed seeds float on water. (2) scarification by soaking in some chemical solution could break seed dormancy of C. kanehirae. (3) seedlings of C. kanehirae grew rapidly. The average length of seedlings could reach 57 cm after 9 months (2013/12~2014/9) in Taipei Botanical Garden.
