    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.

To study possibilities for increases of yield of the apple cultivar Cox's Orange Pippin, relevant information was gathered about fruit set and fruit drop, in particular about June drop. The information concerned pollination intensity, amount of fruit set, seed content of the fruit, number of leaves per spur, and the influence of the bourse shoots. Several growth regulators were tested to see whether these can reduce June drop.

The main conclusions drawn from the results of these observations are given in Section 3.1.3. (p. 18). The growth regulators examined were NAA, NAAm, GA 3 , GA 4+7 , BA and ABA. The experimental results are given in Section 3.2.3 (p. 40). The most interesting finding in the latter part of this work was the promising ability of GA 4+7 to reduce June drop.

The factors underlying fruit set, fruit drop, and fruit growth and the possible role of the applied regulators under study are discussed, whereby fruit drop was related with leaf abscission.
