In addition to that, the larger nuculania have a larger number of true seeds (AZEVEDO; MENDES; FIGUEIREDO, 2004) so that the sowing of the larger diaspores may enhance the chances of germination to occur and the development of at least one of those seeds and the production of plantlets.
The diaspores of target species were sown in 9 cm Petri dishes, with two filter papers moistened with 5 mL aqueous leaf extract, oxyfluorfen herbicide (positive control) or distilled water (negative control).
Aluminum hydroxide minerals in various proportions except bauxite are conventionally found in Gibbsite with the combination of [Al (OH) 3] and polymorphs like boehmite and diaspore [AlO (OH)].

Fruit ripening has also been associated with the appropriate dispersal season; for instance, diaspores of wind dispersal species ripen during the dry season (Lieberman, 1982; Morellato et al., 1990; Ibarra-Manriquez et al, 1991; Batalha and Martins, 2004), a situation that also occurs in several species of Asteraceae in the study area.
The tropical belt bauxites contain mostly gibbsite with only traces of boehmite and no diaspore. Gibbsite is the most desirable mineral because it is more readily dissolved in caustic and at lower caustic solution concentration, temperature, pressure, and detention time.
Generally, people access forests to conduct several activities, such as diaspore extraction and hunting, which is facilitated by the occurrence of roads (Peres & Lake, 2003).

(2012) classified the germination of Archontophoenix cunninghamii as adjacent ligular, in which the seedling development happens adjacently to the diaspore.
These results indicate that the energy required to evaporate the water bound to the active sites of the product is always greater than the energy required to evaporate the pure water, as was also observed for seeds of 'tucuma-de-Goias' (Oliveira et al., 2014a), jatropha (Chaves et al., 2015), pequi diaspores (Sousa et al., 2016) and baru fruits
An open-mindedness and investment in a community, of the type encapsulated by Diaspore's Favour Bank project, is needed from all models of gallery to move forward.
