We will follow for the XXIIIrd IHC of 1990 in Florence the same procedure and we have made firm commitments with the Chairmen of Sections, Commissions and Working Groups to publish these volumes at the end of 1991/beginning 1992.
It is clear that these publications can only be realized with the important assistance of these Chairmen, some moderators and editors, the ISHS Secretariat and the authors using the ISHS-publishing system.
We are grateful for the work done by Professor H.D. Tindall for the first part of this volume and for the work done by Professor F.G. Dennis, for the second part of this volume of Acta Horticulturae on Tropical Fruits and Temperate Zone Fruits in the Tropics and Subtropics which consists of papers presented at the XXIIIrd International Horticultural Congress, Florence, Italy.
We want to thank Professor Dr.
R. von Alvensleben for the contribution of the part of this Acta Volume consisting of papers which were presented at the Symposium on Horticultural Economics in Developing Countries, Alemaya, Ethiopia, July 1989, which could not be published earlier.
