Abstract: 22 figures. ["For each season of the year there were specific cases of weather conditions which could be classified into uniform types, and the related responses in net photosynthesis and water status are described in schemes and diurnal courses. Further results, as general light and water content dependent photosynthesis curves derived from the measured parameter, and seasonally shifting photosynthesis responses which occurred in some species, are discussed."]
