Sapucaia or Lecythis pisonis Cambess. is an ornamental tree that produces edible, tasty, and nutritious nuts, and can be used for timber production. Sapucaia has potential as a functional food, owing to optimal nutritional and particularly Se levels. The present study sought to characterize the seeds of 21 sapucaia matrices from forest remnants of a neotropical hotspot (Atlantic Forest) and farms in two Brazilian states. Biometrics, germination, vigor, lignin content in the teguments, minerals content, and phenotypic and molecular diversity were analyzed. The seeds of matrices 16 and 21 were the most vigorous. Nuts from matrices 21 and 17 contained the highest amounts of Se. Matrices 5, 8, and 21 were the most phenotypically distant; whereas matrix 21 was the most genetically distant. Importantly, we validated a new non-destructive and efficient X-ray-based methodology for internal and densitometric analysis of sapucaia seeds, and demonstrated a high genetic divergence among matrices.
巴西栗（Lecythis pisonis Cambess.）是一种观赏性树木，其果实为可食用、美味且营养丰富的坚果，同时可用于木材生产。由于其具有最佳的营养成分，特别是硒含量，巴西栗有作为功能性食品的潜力。本研究旨在对来自新热带热点地区（大西洋森林）森林遗迹以及巴西两个州农场的21种巴西栗母树的种子进行特征描述。分析了种子的生物特征、发芽率、活力、种皮中的木质素含量、矿物质含量以及表型和分子多样性。母树16和21的种子活力最强。母树21和17的坚果含硒量最高。母树5、8和21在表型上差异最大；而母树21在遗传上差异最大。重要的是，我们验证了一种基于X射线的新型无损且高效的方法，用于巴西栗种子的内部和密度分析，并证明了母树之间存在高度的遗传差异。
