Abstract

At several dry and wet sites in a lowland deciduous forest in Guanacaste, Costa Rica, the rate of leaf fall during the early dry season was strongly correlated with the decline in soil moisture and increasing water stress of trees. Recovery from water stress was required for flowering and shoot emergence. At dry sites rehydration occurred only after isolated rain showers or irrigation; at wet sites it took place during continued drought, probably as a consequence of the decrease in transpiration during leaf fall. Flowering occurs at any time between the beginning (December) and end (May) of the dry season. Differences in the timing and intensity of flowering as well as in the timing of leaf fall and shoot emergence can be accounted for by site-dependent differences in rates of desiccation and rehydration of trees in conjunction with year-to-year variation in timing and intensity of rainfall. -from Authors
