Abstract:
Aimed to characterize the guariroba reproductive and vegetative phenology and morphology and to relate these characteristics with climatic variables, in order to know the species so that future work may be possible from this basic study. Two experimental areas were used, area 1 with a population in the vegetative phase and area 2 in the reproductive phase. For morphological characterization and vegetative phenology, plants from area 1 were used. The collection of vegetative phenology was carried out monthly from October 2008 until January 2010. For this evaluation, the production of green leaves and leaf fall was considered. Morphological characterization data were collected every three months starting from October 2008 to October 2009. In area 2, data on reproductive phenology were collected. For this analysis data were collected fortnightly. Data were submitted to descriptive statistics. Guariroba begins flowering with the opening of the spathe, which happens throughout the year, with intensity at some times of the year. This phenophase correlated 18 positively with humidity in the first, second and third month prior to the occurrence of the event. The female flower phenophase positively correlated with precipitation on the occurrence of the event and up to three months prior to the occurrence. The morphological characterization shows that the growth rate of the stem is stabilized when precipitation decreases. According to the observations, it's concluded that the production of ripe fruits of guariroba occurs from April to June. If the interest is the collection of fruits for planting it should be done in those months where there is a higher production. Morphological characterization is influenced by climatic conditions.
