    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.

Results were presented of studies on the initial growth of Hevea buddings, at the Proefstation West-Java, Buitenzorg (now Bogor). The time elapsing between cutting off the stock above the union and sprouting of the implanted bud was a clonal character; so also was the angle between the young sprout and the stock. The formation was described of successive shoots or leaf storeys. The characteristic periodicity shown by most buddings was not due to an inherent tendency of the plant towards interrupted elongation growth but depended on environmental conditions, the girth of the stock, and the growth vigour of the 62

clone. As these conditions became less favourable, there was a gradual transition from completely aperiodic leaf formation with a constant rate of elongation to periodic shoot formation with increasingly long resting periods between the formation of successive shoots. This periodicity of shoot formation, and the decreasing size of successive leaves within a shoot resulting in its typical umbrella- like shape, were explained as the effect of an interaction between a fairly even moisture supply to the growing point and changing water consumption by the developing leaves.
