ESTABLISHMENT OF A MODEL SYSTEM FOR BIOTECHNOLOGICAL STUDIES OF TROPICAL TREES

本研究的主要目的是建立一套可供进一步生物技术研究的热带林木树种模式体系，如杨树等温带林木。本研究不仅为一些热带速生树种的试管繁殖奠定了基础，如龙须草、合欢树、花椒、印扎等，也为龙脑香科重要用材树种--龙须草的试管繁殖技术奠定了基础。我们还开发了人工种子和原生质体培养技术。这些结果将为热带林木的生物技术提供基础技术。

Main objective of this research is to setablish a model system of tropica forest tree species, which is feasible for further biotechnological researches, just as poplar for temperate forest.We established fundamental techniques of in vitro propagation not only for some tropical fast growing species, such as Gmelina arborea, Paraserianthes (Albizia) falcataria, Peronema canescens and Azadirachta excelsa, but also Shorea roxburgii an important timber tree of Dipterocarpaceae in this research. And we also developed the techniques for artificial seed and protoplast culture. These results should provide fundamental thechniques for the biotechnology of tropical forest trees.
