    Union Catalogue of Agricultural Libraries in the Netherlands

    The WUR Library Catalogue contains bibliographic data on books and periodicals held by the libraries of Wageningen University and Research Centre and some 15 associated libraries. Holding data are added to each record.

    Subjects covered include Agrotechnology, Food and Food Production, Plant and Animal Sciences, Soil Science, Geo-information, Landscape and Spatial Planning, Water and Climate, Ecosystem Studies, Economics and Society.

    The joint collections of the participating libraries cover a substantial part of the internationally available scientific literature in these disciplines.

    As far as Dutch scientific literature in these fields is concerned, coverage can be considered near 100%, including much of the so-called "grey literature".

    All titles are entered in their original language. Keywords are added to facilitate subject searching.

    The database is updated every day and now contains over 830.000 records.

The influence of climatic conditions was investigated on flowering behaviour of pyrethrum ( Chrysanthemum cinerariaefolium Vis.). At low temperatures high numbers of plants initiated high numbers of flower heads. Both the development of the initiated flower heads and the vegetative development of the plants were stimulated by higher temperatures.
The second aspect was the development of methods of vegetative propagation in vivo and in vitro. Through a culture of peduncle explants in vitro detailed information was obtained about the initiation and development of adventitious roots. With these data the process of adventitious root formation of shoot cuttings in vivo was optimalized. In practice this method of vegetative propagation in vivo may be useful for a fast multiplication of selected healthy plants with high yields of pyrethrins. Vegetative propagation was also achieved by initiation and development of adventitious shoots on capitulum explants cultivated in vitro and subsequent adventitious root formation of detached shoots. This procedure was applicable for vegetative propagation of several other Compositae.
