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.
