“…Additionally, these fluctuations in dimensions may be related to climatic factors that affect the synchronization of the fruiting process among individuals during development (Mata et al, 2013) or may also reflect seed quality (Oliveira et al, 2020;Gomes et al, 2023). Due to this variability, for some species like Mimosa caesalpiniifolia Benth., fruit biometric parameters were not effective in assisting in maturity point determination (Alves et al, 2005).…”

Studies on seed maturation directly contribute to obtaining seeds with a higher standard of physical, physiological, and sanitary quality. Thus, the aim of this study was to verify the morphological and physiological changes during the maturation of Cenostigma tocantinum Ducke seeds. The maturation stages were analyzed: I (293 days after anthesis - DAA), II (322 DAA), III (350 DAA), and IV (356 DAA) through visual, biometric analyses, and quantification of moisture content, dry mass, viability, and seed vigor. During the development of C. tocantinum seeds, changes in fruit coloration and an increase in fruit and seed length, width, and thickness were observed. In the initial stages, the seeds had a high moisture content, which decreased in the later stages. On the other hand, the dry mass of the seeds showed an inversely proportional behavior to the moisture content. Physiological variables performed better in stages III and IV, except for electrical conductivity. It can be concluded that C. tocantinum seeds showed superior physiological quality in stages III or IV, recommending the collection of seeds during these maturation periods.

“…These changes may result in less insect visitation to fl owers and reduced pollen deposition, reducing seed production and gene exchange between diff erent populations of M. urundeuva. This species seeds quality is related to the maximum, average, and minimum temperature, average and minimum humidity, and precipitation (Oliveira et al, 2020). However, these climate variables during the diff erent phenological phases of M. urundeuva aff ect the physiological quality of the seeds, and, in climate change scenarios, there will be a reduction in the seed production of this species (Oliveira et al, 2020).…”

In this work, the prediction of the distribution of M. urundeuva Fr. All. was performed based on the region of natural occurrence of the species. Its geographic coordinates were obtained from online databases CRIA and SpecialLinks, from scientific articles and fieldwork carried out by Universidade Estadual Paulista (UNESP) in Ilha Solteira, São Paulo, Brazil. M. urundeuva is a native tree species with great potential for commercial use in Brazil. For this purpose, ecological niche modeling was used, with current layers of climate variables and layers prepared for future climate scenarios, according to the 4th Report of the Intergovernmental Panel on Climate Change (AR4/IPCC), using Worldclim data on Brazil. With the Open Modeller and ArcGIS programs, maps were generated to predict its occurrence for the current period and future climate scenarios, made according to the projections of global climate changes. With the projection of increases in temperature and precipitation in the area where the species occurs, it tends to migrate to areas of Brazil where the climate is currently milder, in the south and southeast regions. Due to climatic changes, the species tends to undergo changes in distribution and area size until 2080. It was projected for Caatinga and Pantanal, in both periods, an increase in area, while for the Cerrado, in the first period, the area increased, and, for the second, it decreased. Therefore, according to the results of the maps of future projections for the next decades, it is concluded that there will be changes in the distribution of M. urundeuva, with a significant reduction of the potential area of occurrence in the region.

Global efforts to restore ecosystems have increased the demand for seeds of native species, both from tree-shrub and herbaceous strata. However, little is known about seed ecology or germination of many herbaceous species from the Brazilian Caatinga. Neoglaziovia variegata (caroá) is a bromeliad endemic to this biome and has great ornamental and fiber production potential. This study aimed to morphologically characterize N. variegata fruits and seeds and to evaluate its germination-related parameters. To do so, the morphometry of bunches, fruits, and seeds was investigated, and seeds were assessed for physiological quality at two maturation points and light response. The morphometric measurements showed normal distributions and a wide dispersion from the central values. Therefore, there is genetic variability among individuals of the same population. The seeds showed high germinability, and fruits had an average size of 8.5 x 9.4 cm, whose color (green or purple) did not influence their physiological quality. The seeds of N. variegata are positive photoblastic, and their germination reaches maximum values after two weeks in the presence of light.
