Role of the corona in Passiflora caerulea (Passifloraceae) as attractant to their pollinators. Passiflora caerulea L. flowers, like those of many other zoophilic species, offer nectar as reward to their pollinators as a primary attractant. This species has developed stimuli or secondary attractants...

Role of the corona in Passiflora caerulea (Passifloraceae) as attractant to their pollinators. Passiflora caerulea L. flowers, like those of many other zoophilic species, offer nectar as reward to their pollinators as a primary attractant. This species has developed stimuli or secondary attractants that announce the presence of primary one (i.e. the nectar) and ensure repeated visits from their pollination vectors optimizing reproduction. The corona, a characteristic structure of the Passifloraceae family, has been reported for P. caerulea as the organ that produces visual and olfactory stimuli on their pollinators. By preference experiments, nullifying either one or both functions, the importance of each one in attracting pollinators was evaluated. The suppression of functions, individually and together, produced a significant decrease in the number of visits compared to the controls. Thus, the importance of visual and odorant functions was verified; greater efficacy was recorded for the last one in the frequency of visits. Additionally, the volatile compounds produced by the flowers were identified, some of which were produced by the perianth and not by the corona, as was expected. Las flores de Passiflora caerulea L., como las de muchas otras especies zoófilas, ofrecen néctar como recompensa a sus agentes de polinización a modo de atrayente primario. Esta especie ha desarrollado estímulos, o atrayentes secundarios, que anuncian la presencia de los primarios y que garantizan las visitas repetidas de los vectores de polinización optimizando su reproducción. En P. caerulea, la corona, una estructura característica de la familia, ha sido citada como estructura productora de aromas atrayentes y, en conjunto con otras piezas florales, estaría encargada de producir estímulos visuales y olfativos sobre sus polinizadores. Mediante experimentos de preferencia, anulando una o ambas funciones, se determinó la importancia de cada una de ellas. La supresión de las funciones, tanto de manera individual como en conjunto, produjo una disminución significativa en la cantidad de visitas con respecto a los controles. De esta manera, se verificó tanto la importancia de la función visual como odorífera, aunque se registró mayor efectividad de esta última en cuanto a la frecuencia de visitas. Adicionalmente, se identificaron los compuestos volátiles producidos por las flores, algunos de los cuales fueron, sorprendentemente, producidos por el perianto y no por la corona como se esperaba.
