The Leguminosae family has a wide geographical distribution and presents a great diversity of species in the most varied environments. Currently, the family is circumscribed in six subfamilies: Caesalpinioideae, Cercidoideae, ...

The fine-scale effects of fire and the consequences for seed survival are poorly understood, especially in the Cerrado (Brazilian savannas). Thus, we investigated whether vegetation gaps (bare soil patches) influence the ...

Few works report the use of degree-days (DD) – used in crops to predict events and schedule management activities – to describe the germination of tropical trees. The cardinal temperatures (base, optimum and ceiling ...

Ormosia paraensis Ducke has ornamental seeds widely used in the manufacture of bio-jewels and wood used in the furniture industry. For seedling production, the information on its seed physiology is scarce. Thus, the aim ...

Caesalpinia echinata and C ferrea var. ferrea have different seed behaviours and seed and fruit types. Comparison of the seed ontogeny and anatomy partly explained the differences in seed behaviour between these two species ...

Data about morphological and anatomical features of seeds are important for studying phylogenetic relationships in angiosperms and can provide ecological information referring to the taxa. In most species, the final step ...

The seed coat externally covers the seed, and its primary function is to protect the embryo. In mature seed, testa, and tegmen, if differentiated, can prevent germination if there is impermeability. Impermeable seed coats ...

(Morpho-anatomical studies of seeds and seedlings of wild indigo, ""anileira"", Indigofera-Leguminosae). The common name ""wild indigo"" specifies Indigofera will L., I. suffruticosa Mill. (legitimate name) and I. truxillensis ...
