The authors remind the reader of the definitions of 'seasonal', 'seasonality' and 'phenology'. The impact of physical factors (radiation, rainfall, air and soil moisture, photoperiodism) on vegetation is reviewed with regard to tropical regions. The object of observations (chlorophyllous synusia, flowering, fruiting, girth changes) as well as their measuring are discussed. Various ways of expressing results are listed and illustrated. Finally gaps in our present knowledge are underlined.
