The bibi iograp hy includes papers in a l I fields of photosynthesis research - from stu dies of model biochemical and biophysical systems of t he photosynt hes is mechanism to primary prod ucti on studied by t he so-ca Ile d growth analysis . In addition to papers devoted enti rel y to photosynth es is, papers on other topics are inc luded if t hey con t ai n data on photosynthetic activity, photorespiration, chloroplast structure, chlo rophylland carotenoid synthesi s and destruction, eta., or if they conta in valuable methodological information (measurement of selected environmentaI factars, leaf area, eta.) . In many branches it has been difficult to defi ne th e limits of int erest for photosynthesis researchers. This problem has arisen e. g. in topics deal ing with t he transfer of gases, where - in addition to t he papers on ca rbon dioxide transfe r - so me pape rs on water vapour transfer are included, these being of general appl icat ion or bringing new approaches . On th e other hand, m any papers deal ing wit h the anatomy and phys io logy of stomata have been omitted, if the aspect of ca rbon dioxide or water vapour exchange has not been discussed.
