“…O presente trabalho faz parte do projeto elaborado por Melhem et al (1984), que visa caracterizar morfologicamente os grãos de pólen das famílias ocorrentes na Reserva do Parque Estadual das Fontes do Ipiranga (PEFI), com o objetivo de complementar os levantamentos taxonômicos realizados na mesma área segundo planejamento apresentado por Melhem et al (1981) e finalizado em Nakajima et al (2001). O formato atual segue Cruz- Barros & Souza (2005). Devido à sinonimização do gênero Chamaesyce em Euphorbia, as espécies tratadas em Chamaesyce na monografia da família Euphorbiaceae para o Parque Estadual das Fontes do Ipiranga (Cordeiro 1989), aparecem no presente trabalho em Euphorbia.…”

Pollen morphology inAthenaeaSendtn. andAurelianaSendtn. (Solanaceae)

et al. 2015

View full text Add to dashboard Cite

Aureliana and Athenaea (Withaniinae, Solanaceae) are two genera of shrubs or small trees with centres of diversity in the Brazilian Atlantic Rain Forest. They are difficult to distinguish using gross morphology, and are traditionally segregated based on differences in fruiting calyx size. Pollen grains of all taxa were acetolysed, treated and examined with light and scanning electron microscopy, with the aim of identifying diagnostic characters. Microphotographs and illustrations of pollen grains are presented. The species analysed present small-to medium-sized monad pollen grains of varying morphology with long to extremely long colpi, and lalongate endoapertures. The analysis showed that the pollen grains of both genera are very similar, differing in size-related characters. These data contributed to the synonymisation of Athenaea within Aureliana.

“…The pollen morphology of various genera and species of Solanaceae has been described by different types of studies: Pollen morphology of the family in general (Guang-Fang et al 1985;Bernadello & Luján 1997;Khatamsaz & Zangirian 1998;Batista-Franklim & Gonçalves-Esteves 2002;Rojas & Laportte 2004;Rodrigues et al 2016;Dhanya & Devipriya 2016); Pollen morphology of Cestrum or Solanum (Murry & Eshbaugh 1971;Silva et al 2003;Al-Quran 2004;Perveen & Qaiser 2007;Batista-Franklim & Gonçalves-Esteves 2008;Lashin 2011;Kumar et al 2015;Vignoli-Silva et al 2015;Song et al 2018) and Pollen flora of some species (Erdtman 1952;Chung & Huang 1972;Salgado-Labouriau 1973;Rao & Ling 1974;Punt & Monna-Brands 1977;Roubik & Moreno 1991;Velásquez & Rangel 1995;Melhem et al 2003;Barth & Duarte 2008;Cruz-Barros et al 2011;Mercado-Gómez et al 2013;Silva et al 2014Silva et al , 2016Lorente et al 2017).

Solanaceae is represented by herbs, shrubs, trees and climbing plants and has cosmopolitan distribution, with a large number of native species in the Neotropical region. This study aimed to characterize the pollen morphology of ten species of Solanaceae (especially species of Cestrum and Solanum) from Cerrado forest fragments in Brazil, in order to contribute to the palynology, taxonomy and conservation of degraded areas. Pollen grains were acetolysed, measured and photographed using light and scanning electron microscopy. Qualitative data were described, and quantitative data were analyzed statistically according to sample size. Morphologically, the studied pollen grains vary in size (small to medium), amb (subcircular to subtriangular), shape (oblate spheroidal to subprolate), aperture details (very long, long or narrow colpi, rounded or tapered at the polar ends, colpi with margo, sometimes with a fastigium, endoapertures can present costa and median constriction) and ornamentation (psilate, rugulate, striate or microreticulate). We observed rugulate or striate pollen grains without fastigium for Cestrum species, whereas psilate or microreticulate pollen grains with fastigium were observed for Solanum species. Qualitative data on diameters and aperture measurements were also found to be important in characterizing the two genera. The results obtained here confirm Solanaceae as an eurypalynous family.
