“…The data presented here for seed dimensions are close to those of Machado, et al (2016), in a study with matrices from the Goiás state region, and of Pimenta, et al (2013) in headquarters located in Mato Grosso. The variation in seed size of A. crassifl ora is normal for polyspermic fruits where there is competition for nutrients, which aff ects the fi nal size.…”

With the existing reduction of the vegetation cover of the Cerrado, several tree species have their areas of occurrence diminished, and as a consequence, they lose part of their genetic diversity. To counter this scenario it is necessary to know the genetic diversity in order to base projects and practical conservation measures. Thus, the objective of this work was to investigate the genetic variability of Annona crassiflora by means of morphometric data of fruits and seeds in four populations in central Brazil. In total, 152 fruits were obtained from 73 matrices, of which the height, diameter, fruit mass, mass of 100 seeds and number of seeds per fruit were measured. The fruits were stripped and the seed removed to measure their height, width and thickness. The hierarchical cluster study showed the grouping of 11 small groups and two large groups, and in these two large groups there are representatives of the four populations sampled. This shows that there is no specific division of populations, indicating high genetic variability. The fruits of the Buritis population were, as a rule, significantly larger than those of other populations, which may indicate genetic distancing or different environmental conditions of pollination and dispersion. This pattern was not observed in the seed size analysis, although there was a statistical difference between the populations. In general, the largest dimensions were found in the populations of Planaltina and Buritis. Therefore, the analyzes indicate high genetic diversity and fruits/seeds with larger dimensions in the best-preserved state.

“…O caráter epígeo e a fanerocotiledonia em P. rufum também foram constatados por Gogosz et al (2010), Pimenta et al (2013), Haliski et al (2013), Bassaco et al (2014) e Gomes et al (2015) onde averiguaram que a germinação é epígea e fanerocotiledonar em Campomanesia xanthocarpa., Annona crassiflora Mart., Casearia decandra Jacq., Sebastiania brasiliensis Spreng., P. cattleyanum e A. sellowiana. Na maioria dos casos, o caráter epígeo está associado a fanerocotiledonia e o hipógeo, à criptocotiledonia (Beltrati & Paoli 2006).…”

RESUMO -O objetivo desse estudo foi descrever e ilustrar a morfologia de frutos, sementes e plântulas de Psidium rufum DC. com o propósito de auxiliar nas mais diversas áreas, como a taxonomia e a silvicultura. A espécie é uma frutífera não cultivada, mas com grande potencial ecológico. Para a caracterização das estruturas e descrição das fases de germinação foram utilizadas 100 unidades aleatórias de frutos e sementes provenientes de Curitiba e Ponta Grossa, Paraná. P. rufum apresenta frutos lisos, brilhosos, glabros, de cor vermelho-arroxeado quando maduros, de forma globosa, carnosos e indeiscentes tipo bacoide. As sementes são campilótropas, reniformes, com tegumento liso, opaco e pétreo, apresentam um possível tecido endospermático oleaginoso de coloração creme. O embrião é do tipo pimentoide e a germinação é epígea fanerocotiledonar, iniciando no 15º dia e estendendo-se até o 37º dia. As características morfológicas apresentadas são informações úteis para auxiliar no reconhecimento de P. rufum.

(Myrtaceae).The objective of this study was to describe and illustrate the morphology of fruits, seeds and seedlings of Psidium rufum DC. in order to assist diff erent disciplines, such as taxonomy and forestry. The species is a fruit that is not cultivated, but has great ecological potential. For structure characterization and germination stage descriptions, 100 units of random fruits and seeds of Curitiba and Ponta Grossa, Paraná were used. P. rufum fruit is smooth, shiny, hairless, with a red-purple color when ripe, so globosa, fl eshy and indehiscent type bacoide. The seeds are campylotropous, reniform, with smooth, opaque and stony seed coat, and presented a possible endospermatic tissue and linseed in cream coloring. The embryo is of the pimentoide type and germination is epigeous phanerocotyledonal, starting on day 15 and extending to day 37. The morphological characteristics presented are useful in helping identify P. rufum.

“…The seeds were used in water for 12 h and sectioned crosswise and longitudinally with steel blade for observation of the embryo, as well as its position inside the seed. The user characteristics were analyzed for identification (Brito et al, 2014;Castenllani et al, 2008;Groth, 1989;Pimenta et al, 2013;Trindade et al, 2021) For the analysis of the ornamentation of the seed cout, a repetition with three seeds for each species, extracted from ripe fruits, after moisture removal was fixed in stubs and metallized with pale gold and examined under scanning electron microscopy (SEM).…”

This study aimed to describe and characterize the biometry of the fruits, and seeds of three species of Solanum (Solanaceae) from the Amazonia. Biometry can help the development of efficient techniques for the management and understanding of the species. The morphometric characterization of the structures was performed from 100 fruits and 100 seeds, collected in the Metropolitan Region of Belém from the Amazonia. And analysis of the ornamentation of the seed scanning electron microscopy (SEM). The fruits are polyspermic, fleshy, berry-type, dehiscent, consisting of one or two locules with the seeds attached to the axial placenta, with five lobes on the end, glabrous, green when immature, purple and red in S. americanum and S. stramoniifolium and pulbescent greens in S. crinitum, when ripe. The seeds are obovoid to subdiscoid, little to very compressed. The forehead ornamentation is reticulated with straight to sinuous walls and the presence of filiform projections. Internally, the seeds are albuminous with a gelatinous endosperm surrounding the entire embryo of the axial type, continuous linear circined to imbricate. The weight of 1,000 seeds was higher for those in S. crinitum 2.36 g, followed by S. stramoniifolium with 1.67 g and S. americanum with 0.4 g.
