Rainfall as a Factor in the Release, Timing, and Synchronization of Anthesis by Tropical Trees and Shrubs

Abstract

Although a number of studies have described seasonality of flowering by tropical plants (most often trees) either at the species or community level, for tropicalplants there have been few studies treating the induction of reproductive structures, their ensuing development, or the triggering of anthesis (opening of the flower). In this paper we present data which demonstrates that rainfall, either directly or indirectly, is an important timing and spacing mechanism for the flowering of at least some tropical plants. We also attempt to relate this phenomenon to some prior relevant studies on flowering in the tropics.
