Abstract
一、Establishment of production system of ecological forestry with multi-function
Sustainable wood value chains that are environmentally friendly, socially responsible, and economically sound are key to making progress towards the Sustainable Development Goals (SDGs in 2030), viz namely SDG8 (decent work and economic growth), SDG12 (responsible consumption and production), SDG13 (climate action), and SDG15 (life on land) according to experts at the Sustainable Wood for a Sustainable World global meeting at FAO Headquarters in Rome in 2017. For promoting sustainable wood value chain, it is understandable to reveal the investment obstacles and opportunities, thus to benefit investment of industry. Agricultural enterprises and forest farmers in village of Taiwan are not interested in investing on produce forestry products for the long-term growth of trees. Based successful plantation system of multilayer forest to produce both timber and byproducts, we will establish sustainable wood value chain cooperating with industries who stationed at Innovation Incubation Center of Taiwan Forestry Research Institute, or technology transfer companies. Two areas of multilayer forest will be established for production of forest major and by-products. The management of multi-functions with ecotourism, forest food and therapy will made around these multilayer forests.二、The study on the cultivation and seed oil utility of the oil trees.
There are some plantations on the Sapium sebferium, Aleurites moluccana and Calophyllum inophyllum were established in Taiwan. The seed oil of those trees is the good base oil for the cosmetics products. The former study on TFRI already initiated pilot cosmetic products such as hand care cream, skin care cream, and skin ointment. While the seed mass production techniques on those trees are in need of establish ment, besides the seed oil utility also beyond the cosmetics production. The purpose of the study is to establish the techniques of grafting and coppice forest on those trees for the seed economical production which may promote the seed products economical utility on the plantations. The established techniques will encourage the local material supply for the cosmetics and food industry while will decrease the import needs.The development for valuable economical product will promote the primary agro-forestry products value besides will increase the profit of local farmer. Mixed or multipurpose plantations on those trees will such as mushroom use woods or long-term harvest woods encourage the local forest utility and income profit. The research is to study the agronomy characters of Jatropha hybrids among the regional trial. We are expecting a shrubby form, early flowering and local adapted hybrids was selected.三、The study on the under-forest economy of Camellia formosensis
Camellia formosensis is a potential plant on under-forest economy research. In order to give consideration to economy, Public welfare and Sustainability, it is necessary to do the research about ecology、plant nursey and chemical components. The aim of this research try to finish following items. (1)Phenology (2)structure and component of forest, generation mechanism of Camellia formosensis. (3)pick the good variety of Camellia formosensis (4)The analysis of chemical components by different attitude. The result will be helpful to conservation of Camellia formosensis, promote the income of tea industry.四、Taiwan-Japan collaboration on the Calophyllum inophyllum in provenance collection, growth investigate and bigger fruits variety silviculture.
The Calophyllum inophyllum ancestors' trials of 39 families were established among Iriomote Japan, Ilan and Henchun Taiwan in 2014 and 2105 in respectively. In the long-term monitoring of tree high, stem growth and physiology or phenology traits from the trees' performance we expect to select a wind resistance plus tree. Besides when the DBH growth over 10cm the wood density will be censused to select the plus tree. The tree form traits such as tree high, branching high, stem straightness, and DBH growth will censused every 6 months. There are some bigger fruits ed trees were founded along the road side and we collected the seeds to raise seedling for the ancestor study and the young branches were also collected for the grafting scions to establish a seed mass product plantation in the future.五、The development of economic forest by products under forest canopy.
Extracts of Goniophlebium formosanum (Baker) Rödl-Linder hold anti-oxidation and anti-ultraviolet damage active materials. Their overall effect is better than those of well-known essential oils and skin care whitening cosmetics. However, simply relying on wild source to obtain the source may lead to a predatory exhaustion for commercialization. Therefore, this study will establish a green global body liquid culture system for Goniophlebium formosanum as a raw material for cosmetic activity.
This study focus on the seed storability and germinated mechanism of Zanthoxylum ailanthoides, a Taiwan native tree species with economic development potential. The objectives of this project are to investigate the germinated mechanism and find out the dormancy-breaking conditions for germination, and to identify the seed storage behavior of Zanthoxylum ailanthoides is orthodox and show long-term seed storability or not. The result will be a database for silviculture and provide recommendations of preservation strategy of this species.
Tuber elevatireticulatum was the first published white truffle in Taiwan, and a new species in the world. Due to the few fruiting bodies collected, the cultural and conserved methods was developed. Semi-sterile seedlings will be prepared for the inoculation test to make sure the host range of the white truffle.
