Yang Jiaju Cheng Fang(Research Institute of Wood Industry, Chinese Academy of Forestry. Beijing)
The WIP-89 Wood Identification System was developed using a Sun 386-24 microcomputer and Turbo Pascal.The database includes.(1)Six hundred and sixty-nine Chinese species (169 softwoods and 500 hardwoods),(2) Ninety multistate characters (43 for softwood and 47 for hardwood) consisting of 317 singular index characters (138 for softwood and 179 for hardwood); (3) Check numbers of the average value of the vessel(tangen-tial)diameter,and the average value and variation range of the vessel and fibre length for each species.The main functions of the system are.(1) Ima5e display showing 27 images of wood anatomy features (8 for softwood containing 13 wood characters and 19 for hardwood containing 37 wood characters);(2) Searching for wood species.(3) Display, printing and modification of the database.(4)Modifying wood character codes and species names before and after searching.(5)Listing different characters among remaining species (less than 10);(6) Listing full and abbreviated family names.(7) And,a species catalog of the families and genera.
