In plant behavioral ecology, plant behavior is defined as environmentally induced (e.g. chemical, UV) phenotypic plasticity. Plants' ability to rapidly and reversibly respond to stimuli thereby effecting morphological plastic growth (i.e. variable morphological characteristics over time with respect to stimuli) with increased basal fitness generally defines this unique behavior. In this paper, we described fruit bicoloration behavior in selected plant species found in Panay Island, Philippines. We argued for the best definition of a genuine bicolored fruit display by examining how this signal design fare on Hasson's amplifier effect theory. A genuine bicolored fruit displays two colors in the mature stage (e.g. Dehaasia sp., Clerodendrum sp., etc.) that promote higher fitness of the signaler (e.g. plant) by improving fruit visibility relative to the animal disperser. It also usually involves color contrast between the fruit and the pedicel. Physiological perspectives in the exhibited plant behaviors (e.g. fruit bicoloration) were shown to broaden future research insights in endogenous signals leading to morphological signal design in plant-animal communication study.
