Seed biometry according to the canafístula maturation stage

Canafistula is a species of great ecological relevance and economic potential. To promote its propagation, it is essential to understand the factors that affect seed quality, especially biometrics and the maturation stage. Given the importance of maturation and biometrics in the quality of canafistula seeds, this study aimed to evaluate the variation in biometric attributes throughout the maturation stages and to determine the ideal stage for seed harvest. The seeds were collected from the crowns of 10 trees according to the maturation stage (green seed, green-to-brown transition, light brown and dark brown), and the following parameters were evaluated: longitudinal length, width, thickness, dry mass and water content of the seeds. seeds. The maturation process significantly affects the biometric and physiological characteristics of canafístula seeds. Seeds in the early stages of maturation (green) had larger dimensions due to their high moisture content, whereas seeds in more advanced stages (dark brown) had greater accumulation of dry mass, indicating physiological maturity.
