An experimental chemotaxonomic data-base for the tribe Vicieae
An experimental chemotaxonomic data-base for the tribe Vicieae
In spite of the increasing use of comparative chemical data in plant taxonomy, conventional information systems do not readily allow taxonomists and others to store, collate, access and revise chemotaxonomic data. It was proposed that the creation of a computerised data-base could overcome this difficulty. The intention of this thesis is to test this proposal. A data-base managemant programme, E) 3.0, was chosen for experimentation. After reviewing the facilities of the EXIR program, a number of miniature data-bases used to investigate the most satisfactory database layout using a list of chemotaxonomic data storage and functional requirsments as a yardstick. The selected layout was then used to create a full-scale chemotaxonomic data-base. Records were collated for nonprotein and free protein amino acids, phenolic compounds and phytoalexirs in various organs for a total of 112 species of the tribe Vicicae (Leguminosae). Approximately 35% of this data was collected directly from laboratory analyses, partly of new material not analysed before and partly as repeat analyses for calibration and checking. The remaining 65% consisted of data taken from the literature. All of this data was entered and the resulting data-base tested. Finally a number of exercises were undertaken to demonstrate the use of the chemotaxonomic data-base for locating and handling chemotaxonomic data, for combining chemical and other kinds of data, for the independent analysis and utilisation of data subsets and for revising the data stored. The results confirm that chemotaxonomic data-base have a useful role to play in providing (1) a storage and retrieval facility for use in ordinary chemotaxoncmic studies (2) a data service for use by other taxonomists and (3) an information service for biologists and others outside the taxonomic profession. Finally the need is discussed for further developtent of computer programs and for their implementationin chemotaxonomic studies.

Abstract
In spite of the increasing use of comparative chemical data in plant taxonomy, conventional information systems do not readily allow taxonomists and others to store, collate, access and revise chemotaxonomic data. It was proposed that the creation of a computerised data-base could overcome this difficulty. The intention of this thesis is to test this proposal. A data-base managemant programme, E) 3.0, was chosen for experimentation. After reviewing the facilities of the EXIR program, a number of miniature data-bases used to investigate the most satisfactory database layout using a list of chemotaxonomic data storage and functional requirsments as a yardstick. The selected layout was then used to create a full-scale chemotaxonomic data-base. Records were collated for nonprotein and free protein amino acids, phenolic compounds and phytoalexirs in various organs for a total of 112 species of the tribe Vicicae (Leguminosae). Approximately 35% of this data was collected directly from laboratory analyses, partly of new material not analysed before and partly as repeat analyses for calibration and checking. The remaining 65% consisted of data taken from the literature. All of this data was entered and the resulting data-base tested. Finally a number of exercises were undertaken to demonstrate the use of the chemotaxonomic data-base for locating and handling chemotaxonomic data, for combining chemical and other kinds of data, for the independent analysis and utilisation of data subsets and for revising the data stored. The results confirm that chemotaxonomic data-base have a useful role to play in providing (1) a storage and retrieval facility for use in ordinary chemotaxoncmic studies (2) a data service for use by other taxonomists and (3) an information service for biologists and others outside the taxonomic profession. Finally the need is discussed for further developtent of computer programs and for their implementationin chemotaxonomic studies.
