Over a 12-week period, new growth was collected at different intervals from Camptotheca acuminata trees to determine whether a leaf harvest strategy would be an efficient means for the production of the alkaloid camptothecin. Because camptothecin accumulates in young leaves and because the harvesting of young tissue stimulates axillary bud outgrowth, this strategy increased the harvestable amount of camptothecin from trees in a nondestructive manner.
在12周的时间里，从喜树树上以不同间隔收集新生长的部分，以确定叶片收获策略是否是生产生物碱喜树碱的有效方法。由于喜树碱在幼叶中积累，并且由于收获幼嫩组织会刺激腋芽生长，这种策略以非破坏性方式增加了从树上收获的喜树碱量。
