Features

The Niu-Chang tree is a native, unique species in Taiwan, and because of its rough and sturdy shape, it is called "Niu" hang. Niu-Chang seeds are difficult to reproduce, and in recent years, the Forest Research Institute has used tissue culture to rejuvenate old trees and restore growth that has been reported in many reports (Ball 1987, Franclet 1991). Therefore, establishing a micropropagation system for Niu-zhang is important for the establishment of Niu-zhang reforestation systems.

The flowers of the Niu-Chang tree are sticky and insect-pollinated, and it is difficult for the mother tree to be pollinated between trees, and many of them bloom at the top of the tree crown, easily damaged by wind, and occasionally seeds are eaten by birds and animals before they are ripe, so it is extremely difficult to collect. In the natural state, there are also few natural regeneration stands, and occasionally natural seedlings, but also because of the lack of light under the forest, the seeds are not easy to germinate due to the thick dead branches and fallen leaves, and many failed, the reason why it is not easy to find Niu-Chang seedlings under the forest.
