“…Additionally, environmental (precipitation and temperature) and plant variables (PlantH and TrunkH) were found to affect the reproductive phenology of the species, and consequently its seed production potential. Studies concerning variations in phenological behavior within and among woody plant populations and their habitats can help to better understand their spatio-temporal variations as survival strategies in different environments (Goulart et al, 2005;Santos et al, 2020;Costa et al, 2021) and aid in elucidating how local abiotic factors and plant traits influence phenological patterns (Moraes et al, 2017;Neves et al, 2017;Santos et al, 2021).…”

Studies of plant phenology in the Atlantic Forest can be enhanced by a greater understanding of the factors regulating vegetative and reproductive cycles. Dalbergia nigra (Vell.) Allemão ex Benth. is endemic and vulnerable in the Atlantic Forest. We analyzed abiotic aspects and plant traits that modulate the phenologies of D. nigra by monitoring 135 individuals in four subpopulations from different remnant forests for 24 months. The growth and shapes of the plants, as well as environmental variables, were determined. Circular analysis evidenced phenological variations among subpopulations and evaluation periods. Multiple factor analysis evidenced that phenological variations are mainly correlated with precipitation, temperature, and tree height. The combination of environmental conditions and plant characteristics affect synchronicity and phenological intensity. Low fruiting intensity (less than 50%) limits seed production and recruitment. We emphasize the importance of forest remnants and the need to increase D. nigra populations in future reforestation projects.

“…Foliar (leaf fall and flushing) and reproductive (flowering and fruiting) phenophases were followed, with their intensities being estimated in classes of 0-4 (Fournier, 1974). We examined aggregation phenological data using circular statistics (Morellato et al, 2010;Santos et al, 2021) in the R environment, with the addition of the "circular" package 3.2.3 (R Core Team, 2014). The frequency of each phenophase was calculated based on the total number of individuals showing the phases per month.…”

Inflorescence Position Influences Phenological Rhythms in Leguminosae Species

We present a case study focusing on the influence of inflorescence position on the relationships between foliar and reproductive phases, focusing on three Leguminoseae tree species in the Chapada Diamantina, Brazil. Both Senna multijuga and Copaifera langsdorffii produce terminal panicles and showed vegetative and reproductive phenophases that were correlated but segregated in time, with the marked concentration of reproductive data. The presence of axillary inflorescences on Inga cayennensis enables the simultaneous production of both flowers and leaves, without the segregation or the correlation of those phases, with a uniform distribution of reproductive data. This study encourages further investigations regarding the effects of inflorescence position on plant phenology.
