The seventh volume of Water-in-Plants Bibl iography includes papers in al I fields of plant water relations research which appeared during the year 1981 - from theoreti- cal considerations about the state of water in cel Is and its membrane transport to drought resistance of plants or physiological significance of irrigation. In addition to papers devoted entirely to plant water relations, papers on other topics are in- cluded if they contain data on plant hydration level, water vapour efflux, rate of water uptake or water transport, etc., or if they contain valuable methodological in- formation (measurement of selected microcl imatic factors, soi I moisture etc.). We have tried to cover fully the relevant papers which have been publ ished in the most important scientific periodicals and books. Articles appeared in local jour- nals, mimeographed booklets, abstracts of thesis and of symposia contributions, etc., were chosen mostly from reprints received directly from authors. The courtesy of those authors who have already suppl ied us with reprints and I ists of their publ ica- tions is highly appreciated.The manuscript is usually prepared in May and June of the year fol lowing the year which it covers. Unfortunately some reprints come later and thus the respective references appear in the fol lowing volume, with one year de- lay. To maximize the value of the bib I iography the references are arranged alphabetic- ally according to the authors' names, and each volume is provided with three indexes.
