Morfologia de frutos e sementes e morfofunção de plântulas de Moringa (Moringa oleifera Lam.)

The objective of this work was to characterize external and internal morphologic aspects of the fruit, seed, and plant of Moringa oleifera Lam. The fruits were collected in the forest garden of Falculty of Agrarian and Veterinarian Sciences, São Paulo State University, Jaboticabal-SP, Brazil. It was observed that the Moringa fruits are brown simple darkness, dry of the type capsule, tends on average: 28.50 cm of length, 2.21 cm of width, 9.91 g of mass and with 12 seeds by fruit, it considerated fruits of medium and small size. The seeds are brown dark and they present three lines clear chestnut tree. The embryo is oleaginous, has a pair of cotyledons and the germination is hypogeal-cryptocotyledonary. The seed has1.037 cm of length and 1.0 cm of thickness of average and have a considerate medium and light weight (197g/1000 seeds). The germination began eight days after the planting and in the 25th day they left the primary leaves.

Morfologia de sementes e de estádios iniciais de plântulas de espécies de Bromeliaceae da Amazônia

Seeds of Aechmea bromeliifolia, A. castelnavii (Bromelioideae); Dyckia duckei, D. racemosa (Pitcairnioideae) and Tillandsia adpressiflora (Tillandsioideae) were collected in the Amazon regions (Mato Grosso) and studied to describe morphological characterization and post-seminal development, which can be taxonomically useful, and to assess percent germination. All the species have epigeous germination and produce cryptocotyledonary plantlets. Seeds have no dormancy and percent germination is high (over 86%), which facilitates the production of seedlings and conservation studies. Exclusive characteristics of the genera include: the seed coat of Aechmea (Bromelioideae) has mucilage that prevents desiccation; whereas that of Dyckia (Pitcairnioideae) has membranaceous wings and that of Tillandsia (Tillandsioideae) has feathery appendages, both of which make dispersal easier and establish the epiphytic habit. Initial post-seminal development of Aechmea (Bromelioideae) and Dyckia (Pitcairnioideae) is marked by the emergence of primary roots, interpreted as a basal character, whereas that of Tillandsia adpressiflora (Tillandsioideae) is marked by the emergence of the cotyledon, interpreted as a derived character. Dyckia and Tillandsia have a small tank only in the seedling phase while the contrary occurs in Aechmea.

Morfologia do epidídimo de cobaio (Cavia porcellus) em diferentes fases do desenvolvimento pós-natal

The morphological evolution of the epididymal duct of guinea pigs (Cavia porcellus, L.) was studied on 10, 20, 30, 45, 60, 70, 90 and 100 days of age, being complex, which is due to the proper differentiation postnatal in the epididymal epithelium. Thus, it was observed that the initial segment of the epididymis reveals an increase of epithelial height corresponding to the average height of the main tubular epithelium cells, generally progressive after 45 days of age. The epithelial height in the middle segment were higher in younger stages (10 to 45 days) than in the prepubertal age (60 days), and have a decrease among 70 to 100 days of age. The ductular terminal segment starts a gradual decrease of the epithelial heights from puberal age (70 days), until adult age (90 to 100 days). In addition, this segment showed epithelial waviness that disappeared after 70 days of age, when the lumen fills it with sperm and cellular exfoliation. The cell types of the epididymal tubular epithelium, principal cells, basal cells and apical cells, were observed in all ages. In the epididymis of very young animals, there was a predominance of undifferentiated columnar cells. After 20 days of age, there was natural prevalence of the principal cells on other cell types, what is a feature similar to other mammals.

Morfologia, ultraestrutura e morfometria do tegumento da paca (Cuniculus paca Linnaeus, 1766) criada em cativeiro

Considering the lack of detailed information about the morphology of paca, which is the second largest rodent of Brazilian's fauna, with excellent meat quality and, due to the importance of the common integument, we described the morphology, ultrastructure and morphometry of the skin of eight pacas (Cuniculus paca), males and females, through comparative analysis of skin's segments of the cervical, dorsal and medial carpal portions. Macroscopic characteristics of the coat were studied. Part of the segments of cutaneous regions was analyzed by light microscopy, and the other part by scanning electron microscopy. We measured the thickness of dermis, epidermis, stratum corneum, the profiles of the collagen fibers of reticular dermis and the area of filled sebaceous gland cells. The results were analyzed by descriptive statistics and T test (p<0.001). The color of the coat is reddish brown with bristles arranged in groups. The architecture of the skin and skin appendages resembles those of mammals in general, although there are no sweat glands. According to the morphometric analysis, this study shows differences of the skin architecture between male and female pacas and also between various body regions in the same animal.
