    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.

Lunaria annua L. is a species with a juvenile phase and requiring cold for flowering. An annual flowering mutant was obtained with ethyl methane sulphonate. Experiments with shoot and leaf cuttings showed that juvenility was not a character of the whole plant. The juvenile phase was shortened by regeneration of cotyledon cuttings of very young plants.

The effectiveness of vernalization in leaf cuttings closely depended on regeneration of buds before or during vernalization.

Rejuvenation through regeneration is identical with juvenility. Flower induction in vitro in petiole segments of vegetative plants was effective, but only when buds were formed before or during vernalization. Cell divisions were considered to be a prerequisite to reach a certain stage of regeneration. Only from that stage could the low temperature act.

Flower bud initiation in vitro in explants from the main axes of flowering Lunaria plants was influenced by different plant factors and by almost all environmental factors normally affecting growth. The disappearance of the flowering state was considered to be not directly due to meiosis or fertilization, but to plant regeneration.
