ABSTRACT The seeds and seedlings morphological differentiation is a challenge in the early stages of plant growth. This study aims to describe the physical and morphological characteristics of seeds and seedlings of Jatropha mollissima to delimit differences between other species from the same genus. The seeds were placed to germinate for morphological description and their physical characteristics were measured. The J. mollissima presented a 1000-seed weight of 332 g, 3,008 seeds per kilogram, 6.7% of moisture, 1.29 cm length, 0.84 cm width, and 0.66 cm thickness. We verified that the seeds are oval in shape; their colour is dark brown, greyish or mixed colour; they have visible raphe and hilum, and caruncle with beige coloration. The endosperm is oleaginous and involves the embryo with foliaceous and spatulate cotyledons. The embryo is axial, and the hypocotyl-radicle axis has a short cylindrical shape. Germination is epigeal and phanerocotyledonary; leaves have dimorphism and serrated margins with simple trichomes; and their apex is cuspidate or attenuated. Our research demonstrates that it is possible to differentiate J. mollissima from other species of the same genus through morphological characteristics. Therefore, this work contributes to the correct identification of the species, laboratory analysis, and field recognition. growth measured J 1000seed seed 1000 33 g 3008 3 008 3,00 kilogram 67 6 7 6.7 moisture 129 1 29 1.2 length 084 0 84 0.8 width 066 66 0.6 thickness shape brown hilum coloration cotyledons axial hypocotylradicle hypocotyl radicle phanerocotyledonary trichomes attenuated Therefore analysis recognition 100 300 00 3,0 6. 12 2 1. 08 8 0. 06 10 30 3,

Resumo Vários trabalhos qualitativos apontam para o modo limitado com que negros, mulheres e, sobretudo, mulheres negras, têm sido representados na publicidade brasileira. Entretanto, ainda são poucos os estudos que buscam avaliar quantitativamente o tratamento dispensado a personagens brancas na publicidade mainstream das últimas décadas em comparação àquele dado a negros e mulheres. Para ajudar a preencher essa lacuna, este artigo examina o espaço de modelos brancos e negros na publicidade brasileira ao longo de cinco décadas. A partir de uma amostra temporalmente estratificada de anúncios estampados em edições do semanário noticioso brasileiro de maior circulação, codificamos as imagens dos anúncios, focando os personagens humanos retratados. Os resultados apontam para uma manutenção das desigualdades raciais na publicidade e para mecanismos específicos de representação que naturalizam o predomínio sistemático de brancos nas peças publicitárias. sobretudo negras Entretanto lacuna circulação retratados publicitárias

Abstract Several qualitative works point to the limited way in which black people, women and, above all, black women, have been represented in Brazilian advertising. However, only a few studies seek to assess the treatment given to white characters in mainstream advertising compared to that given to blacks and women in a quantitative approach. To help fill that gap, this article examines the representation of white and black models in Brazilian advertising over five decades. From a temporally stratified sample of advertisements published in the Veja magazine, the Brazilian news weekly with the greatest circulation, we coded the images of the advertisements, focusing on the human characters portrayed. The results point to the maintenance of racial inequalities in advertising throughout the period and to specific mechanisms of representation that naturalize the systematic predominance of whites in advertising. people all However approach gap decades magazine circulation portrayed
