“…The seed thickness ranged from 5 to 12.99 mm and reached the highest value in the mother plant 14 and the lowest value in the mother plant 15, located in Cuité and Boa Vista, respectively (Table 3). Frequency of distribution (%) 9-10.9 11-12.9 13-14.9 15-16.9 5-6.9 7-8.9 9-10.99 5-6.9 7-8.9 9-10.9 The longest seed length in the mother plants 1 (Juru), 2 (Sumé), 4 (Guarabira), 6 (Esperança), 8, 9, 10, and 12 (Queimadas), 14 (Cuité), 16, 17, and 18 (Boa Vista), and 19 (Areia) can be explained by the occurrence of adequate conditions of temperature, humidity, solar radiation, wind, and precipitation at the time the seeds were formed, as reported for B. forficata, whose longest seed length reached 18.03 mm, and Caesalpinia ferrea Mart ex Tul., whose longest seed length reached 12.2 mm (DUTRA et al, 2016).…”

“…Biometric analysis can provide subsidies for the study of species differentiation, classification of ecological groups, genetic divergences in the same species (FONTENELLE; ARAGÃO; RANGEL, 2007), and the influence in the germination of the species (DUTRA et al, 2016). Thus, variations in the homogeneity observed in the biometric characteristics of E. velutina seeds are common in different mother plants, as seeds were influenced by biotic and abiotic factors in each collection region during seed development.…”

Erythrina velutina Willd. (Fabaceae) is drought tolerant and has the potential for reforestation in the semi-arid region. The response of its seeds to the environmental conditions of each production area influences their size, weight, physiological potential, and health. Thus, this study aimed to assess how the environmental conditions of the different regions of Paraíba influence the biometric characteristics of E. velutina seeds. Seeds from 19 mother plants collected in Juru, Sumé, Araçagi, Guarabira, São João do Cariri, Esperança, Queimadas, Cuité, Boa Vista, and Areia, in the state of Paraíba, Brazil, were used in this study. Water content, thousand-seed weight, and biometric characteristics (length, width, and thickness) were determined in the seeds from each location. The water content ranged from 3.11 to 6.84%, while the thousand-seed weight was higher in mother plants grown in Sumé and Cuité. Seed length ranged from 9.00 to 16.84 mm, being higher in mother plants grown in Juru. Seed thickness and width ranged from 5 to 12.99 mm and were larger in mother plants from Cuité. Temperature, humidity, solar radiation, wind, and precipitation caused variations in the length, width, and thickness of E. velutina seeds, with higher means observed in mother plants grown in Cuité.

RESUMO A biometria de sementes é uma variável de fácil medição que pode indicar a existência de variabilidade genética favorecendo a produção de mudas com elevado padrão de qualidade. O presente trabalho teve como objetivo avaliar a morfometria e massa fresca de frutos e sementes e a emergência inicial de plântulas de três matrizes de santol [Sandoricum koetjape (Burm. f.) Merr.]. Os frutos e sementes são procedentes de três árvores matrizes localizadas em Belém, estado do Pará. Para as variáveis biofísicas de frutos e sementes foram utilizados 50 e 100 amostras, respectivamente. A emergência de plântulas foi realizada em substrato areia com serragem, na proporção de 1:1, constando de quatro repetições com 25 sementes. Observou-se elevada variabilidade para massa fresca dos frutos e sementes, número de sementes por fruto, massa fresca do número de sementes por fruto. As árvores matrizes de santol apresentaram potencial para coleta de sementes a serem destinadas para produção de mudas.

Bauhinia scandens has potential importance as an ornamental and medicinal plant. Researchers have isolated and identified 1-O-alkylglycerol in the leaves of the B. scandens plant, and established antitumor properties using the Brine Shrimp toxicity test, an internationally accepted bioassay. Although this species has high potential, little is known about the viability of seedling production and the morphology of these plants, particularly in terms of seed characteristics and initial stages of germination. The objective of this study was to characterize the seed morphology, germination, and seedlings of B. scandens. Seed water content, weight, and coloration were evaluated. This study also included a description of seed biometrics, external and internal structures, germination, and seedling morphology. Internal seed morphology was evaluated by the anatomical sectioning and X-ray methods. The morphology data obtained were subjected to descriptive statistical analysis and germination data were determined using Cramér’s V. B. scandens seeds have a coloration ranging from very dark grayish-red to dark reddish-brown, flat oblong shapes, and rounded bases and apexes with full or slightly undulating margins. Healthy seedlings are produced mainly by seeds with well-formed internal structures. The reddish petiole of the seedling leaves is a taxonomic character for B. scandens identification. The non-domestication and genetic variability of this species reflect on the seed and seedling color and size variation.
