Phenology aspects of Passiflora wild progeny BRS Maracujá Maçã, BRS Pérola do Cerrado and BRS Sertão Forte
The objective of this work was to evaluate the phenological behavior of three wild passion fruit progenies in the period from September 2015 to August 2016, under the Savanna conditions in the Central Brazilian High Plains, in Planaltina, DF. Flowering and fruiting periods of BRS Maracujá Maçã (BRS MM), BRS Pérola do Cerrado (BRS PC) and BRS Sertão Forte (BRS SF) were analyzed in natural conditions to verify the beginning, duration and the end of the different phenophases. The observations occurred weekly in the field. Digital photographic records of flowers and fruits of each progeny were taken in plants randomly marked reproductive stages and morphological changes during the reproductive phenology of the progenies were identified and analyzed. The highest number of floral buds and flowers per meter of vertical cordon obtained by progenies BRS PC, BRS MM and BRS SF were 284 (February), 180 (March) and 188 (April), respectively. The highest number of fruits accounted for progenies BRS MM, BRS PC and BRS SF were 75 (March), 91 (April) and 77 (August), respectively. The period of flowering and fruiting in the Savanna conditions in the Central Brazilian High Plains, in Planaltina, DF for these three progenies is of the continuous type, in which there is the production of flowers and fruits throughout the all year.
