Résumé:
Amburana cearensis (Allemão) A. C. Sm., is a tree of great importance for the Caatinga
and adjacent areas. To ensure its conservation and sustainable exploitation, the study
of physiological quality is a crucial factor, as it is directly related to its ability to perform
vital functions. Therefore, the objective of the research was to evaluate the biometrics
and physiological quality of the seeds of Amburana cearensis (Allemão) A. C. Sm.
collected in semi-arid regions. The work was carried out at the Ecology and Botany
Laboratory and the Plant Anatophysiology Laboratory (CDSA/UFCG). The seeds were
collected from matrices located in the municipality of Itapetim - PE and taken to the
laboratory, where they were homogenized, and subjected to biometric analyzes
(weight, length, width and thickness) and physiological quality where the following
parameters were evaluated: water content , germination/emergence,
germination/emergence speed index and seedling length. Thus, it was possible to
verify that the frequency distribution by seed classes presented a weight in the highest
concentration between 0.4000 – 0.4900mg with an accumulated frequency of 91%,
width between the class 10.6 – 11.5mm, with an accumulated frequency of 93%. The
thickness between 4.2 - 4.9mm and an accumulated frequency of 95% and the length
with the highest concentration between 14.1 - 15mm, presenting an accumulated
frequency of 83%. As for physiological quality data, they showed the best results when
subjected to BOD with germination data of 90.1%, IVG of 2.76 and seedling length of
23.08cm. Thus, values obtained that show that Amburana cearensis seeds present
uniform biometric values, with relatively close frequency data, are considered an
important parameter to assist in the characterization of this species.
