The bibl iography includes papers in all f. ields of photosynthesis research - from stu- dies of rrDdel biochemical and biophysical systems of the photosynthesis mechanism to primary production studied by the so-cal led growth analysis. In addition to papers devoted entirely to photosynthesis, papers on other topics are included if they con- tain data on photosynthetic activity, photorespiration, chloroplast structure, chlo- rophyll and carotenoid synthesis and destruction, etc., or if they contain valuable methodological information (measurement of selected environmental factors, leaf area, etc. ). In many branches it has been difficult to define the I imits of interest for photosynthesis researchers. This pl-oblem has arisen e. g. in topics deal ing with the transfer of gases, where - in addition to the papers on carbon dioxide transfer - so- me papers on water vapour transfer are included, these being of general appl ication or bringing new approaches. On the other hand, many papers deal ing with the anatomy and physiology of stomata have been omitted, if the aspect of carbon dioxide or water vapour exchange has not been discussed. This volume contains references to papers publ ished in the year 1979, and, similarly to Vol. 9, also addenda including references published in the preceding peri- od (-i. e. 1966 to 1(78), The numbers of these additional references are labelled with an asterisk (*) in the I ist of references.
