III Foreword Like many other natural fibres, sisal is facing strong competition from synthetic materials. In order to retain its current market share and to re-gain its lost markets, the sisal industry needs to increase both its production efficiency as well as to develop new applications and open up new markets. --The-Gammon ·Fund-for-Commodities is providing-support to the-sisal-sector,-- through its financing of several projects, to attain the same. The Fund-supported project "Product and Market Development of Sisal and Henequen Products" (CFCjFIGHFjOl) has been implemented by the United Nations Industrial Development Organization in Kenya and Tanzania during the years 1997 - 2004. The designated international commodity body for hard fibres, the FAO Intergovernmental Group on Hard Fibres (FIGHF), supervised its implementation. One of the components of this project focused on the improvement of the vegetative material which is the basis of the quality of the sisal plants. The emphasis was both on developing a reliable method of producing high quality, disease-free-plantlets--as-well-as by-passing-thecostly-and time consuming stage of propagation through bulbils in designated nurseries. The method of Meristematic Tissue Culture (MTC) was used in this project in sisal laboratories in both Kenya and Tanzania, with the objective of multiplying promising sisal cultivars to promote the production of standard planting materials and to shorten the time needed by breeders to produce new varieties for commercial production. In order to document the MTC practices developed and used in the project, the current Manualwas prepared by the project. It is hoped that the Manual will provide insights in the techniques and methods applied and serve as a reference document for researchers in the field of sisal (re-) production. Amb.
