喜樹鹼為一種近十年來極熱門的抗癌藥物，作為喜樹鹼的萃取原料，喜樹的藥材包括葉片及莖幹產量是相當重要的，而喜樹營養繁殖體系─扦插，在本研究中試圖建立無性繁殖種苗生產體系。喜樹之扦插適期以春冬兩季為主，冬天扦插可以選用碳水化合物蓄積較多的半硬枝插與硬枝插，以利度過低溫不發根的消耗以及插穗本身的長時間發根障礙，適用IBA濃度為1000ppm、1500ppm、2000ppm，發根率可達83%；春初之際，以半硬枝插為佳，短時間低溫可以降低插穗的養分消耗、減少病原菌的感染，又可避免回溫後芽體大量萌動對碳水化合物的競爭導致存活率下降，搭配IBA 1000、1500ppm發根率可達83%；綠枝插則可以選擇一月下旬過後，營養勢較強時扦插，避免冬天長時間不發根引發的失活、萎凋，使用IBA 2000ppm可以有66%發根率；冬天扦插介質的選擇應該使用排水力較佳的泥碳苔+真珠石混合介質，以利水分之管控；而春天的枝條活力較足夠能在短時間發根，可以使用扦插海綿扦插提高發根率。針對其不同成熟度扦插容易存活的時間進行，可以有效提高各種成熟度的萌芽存活率，而選用適合的生長素濃度則可以加快繁殖過程與育苗品質。
Camptothecin has been acted as a very popular anti-cancer drugs since the past decade, because of the extraction of raw materials in term of camptothecin in which medicine materials come from shoot, stem and leaves, therefore Camptotheca acuminate production has been very important, and a vegetative propagation system of Camptotheca acuminata─ cuttings for nursery plants would be pursued in this study. The suitable period of cuttings of Camptotheca acuminate is in spring and winter. When cutting propagation was conducted in winter, semi-hardwood and hardwood which had more carbohydrate accumulation could be used to facilitate rooting through the long time consumption of low temperature and rooting obstacles. The suitable indole-3-butyric acid concentration were 1000, 1500, and 2000 ppm, the rate of rooting could be 83%; In early spring, the better choice of cutting is semi-hardwood. A short time low temperature reduced the nutrition consumption of cuttings, and the infection of pathogens, but also avoided a large number of buds sprouts competition for carbohydrates due to warm temperature. With IBA 1000, 1500ppm, could promote rooting rate to 83%; soft-wood cutting could be chosen over late Jan., when the nutritional potential of cuttings were strong, more over avoided inactivation and decay caused by long period in low temperature by winter. Using IBA 2000 ppm presented 66% rooting rate; The choice of media for cutting in winter should be used better drainage of peat moss plus perlite mixture, in order to facilitate the control of water, and soft-wood cuttings had enough energy to take for short term rooting, cubic flock could be used to promote rooting percentage. Different maturity cuttings could promote the survival rate by matching their own better cutting time, while the selection of a suitable concentration of auxin could speed up the propagation process and nursery plant quality.
