The bib I iography includes papers in alI fields of photosynthesis research - from stu- dies of model 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- rophyl I and carotenoid synthesis and destruction; etc. , or if they contain valuable methodo I og i ca I information (measurement of se I ected env i ronmenta I *factors, I eat area, etc. ). In many branches it has been very difficult to define the I imits of interest for photosynthesis researchers. This problem has arisen e. g. in topics dealing with the transport of gases, where- in addition to the papers on C0 transfer- some pa- 2 pers on water vapour transfer are included, these being of general application. On the other hand, many papers dealing 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 pub I ished in the year 1976, and, similarly to Vol. 6, also addenda including references pub I ished in the preceding period (i. e. 1966- 1975 ). The numbers of these additional references are label led with an asterisk in the I ist of references.
