Resumo: | The family Cucurbitaceae Juss. is include in Cucurbitales order in the clade Eurosids I, 2295 spp., included in 129 tropical and temperate genera distributed in seven families of different morphological and ecological characteristics. The family has 98 genera and 975 species. In Brazil is represented by about 30 genera and 157 species. This work deals with the taxonomic study of plants of the Cucurbitaceae family Juss. found in the State of Goias, Brazil to contribute information to update the Flora of Brazil. Exsiccatae analyzes were performed deposited in national and international herbaria and conducting expeditions in the study area. 19 genera and 40 species in the area were located, so 09 genera and 28 species of native plants. Relative to native plants, Cayaponia Silva Manso gender had a greater number of species (8 spp.), followed by Melothria L. (6 spp.), Gurania (Schltdl.) Cogn. (4 spp.), Ceratosanthes Adans. (3 spp.) Psiguria Neck ex. Arn.and Sicyos L. (2 spp.), and the genres Melothrianthus Mart. Crov., Siolmatra Baill, Wilbrandia Silva Manso, are represented by only one species each. Pollen morphology of six native and two sub-spontaneous species of Cucurbitaceae occurring in the state of Goias, Midwest Region of Brazil, were analyzed with the goal of understanding the palynology and taxonomy of selected species. Pollen grains were acetolyzed, measured, described, photographed and electromicrographed. Analysis under the SEM was used to elucidate questions about the ornamentation of the exine. Pollen grains are in monads in Cayaponia podantha Cogn., Ceratosanthes tomentosa Cogn., Luffa operculata (L.) Cogn., Melothria campestris (Naudin) H. Schaefer & S. S. Renner, Momordica charantia L., Wilbrandia hibiscoides Silva Manso or tetrads in Gurania lobata (L.) Pruski and Psiguria umbrosa (Kunth) C. Jeffrey; average size, large or very large in monads and very large in tetrads. The openings ranged from pores in Cayaponia podantha, colpores in other monads and pores in tetrads. Regarding ornamentation, spiny sexine were registered in Cayaponia podantha, perforated sexine in Melothria campestris, micro-reticulated sexine in Gurania lobata and Psiguria umbrosa and reticulated sexine in other taxa. Results allowed the distinction between genera, indicating that the pollen morphology contributes to the taxonomic studies and the family is considered eurypalynous. These data emphasize the importance of pollen morphology for the diagnosis of genera into Cucurbitaceae. |

A família Cucurbitaceae possui 98 gêneros e 975 espécies. No Brasil é representada por cerca de 30 gêneros e 157 espécies. O presente trabalho trata do estudo taxonômico e morfopolínico das espécies nativas da família Cucurbitaceae Juss. encontradas no Estado de Goiás, Brasil a fim de contribuir com informações para atualização da Flora do Centro Oeste e do Brasil e com novos dados para a palinotaxonomia. Para o estudo taxonômico foram realizadas análises de exsicatas depositadas em herbários nacionais e internacionais e realização de expedições na área de estudo. Foram localizados 19 gêneros e 40 espécies para a área, sendo até o momento, compreendendo 09 gêneros e 28 espécies de plantas nativas, 10 gêneros em 13 espécies consideradas cultivadas ou subespontâneas. Em relação às plantas nativas, o gênero Cayaponia Silva Manso apresentou um número maior de espécies (9 spp.), seguido de Melothria L. (6 spp.), Gurania (Schltdl.) Cogn. (4 spp.), Ceratosanthes Adams (3 spp.), Psiguria Neck ex. Arn. e Sicyos L. (2 spp.), e os gêneros Melothrianthus Mart. Crov., Siolmatra Baill. e Wilbrandia Silva Manso são representados por apenas 1 espécie cada um deles. Analisou-se a morfologia polínica de seis espécies nativas e duas subespontâneas de Cucurbitaceae ocorrentes no estado de Goiás, região Centro-Oeste do Brasil; com o objetivo de entender a palinologia e taxonomia de espécies selecionadas de Cucurbitaceae. Os grãos de pólen foram acetolizados, mensurados, descritos, foto e eletromicrografados. A análise sob o MEV foi utilizada visando a elucidação de dúvidas sobre a ornamentação da exina. Constatouse que os grãos de pólen são em mônades em Cayaponia podantha Cogn., Ceratosanthes tomentosa Cogn., Luffa operculata (L.) Cogn., Melothria campestris (Naudin) H. Schaefer & S. S. Renner, Momordica charantia L., Wilbrandia hibiscoides Silva Manso ou tétrades em Gurania lobata (L.) Pruski e Psiguria umbrosa (Kunth) C. Jeffrey; tamanho médio, grande ou muito grande nas mônades e muito grande nas tétrades. As aberturas variaram de poro em Cayaponia podantha, cólporo nas demais mônades e poro nas tétrades. Em relação à ornamentação, foram registradas sexina espinhosa em Cayaponia podantha, perfurada em Melothria campestris, microrreticulada em Gurania lobata e Psiguria umbrosa e reticulada nos demais táxons. Os resultados permitiram a distinção entre os gêneros, indicando que a morfologia polínica contribui para os estudos taxonômicos e a família pode ser considerada euripolínica. Esses dados enfatizam a importância da morfologia polínica para o diagnóstico de gêneros em Cucurbitaceae.Submitted by JÚLIO HEBER SILVA (julioheber@yahoo.com.br) on 2017-05-09T20:03:31Z No. of bitstreams: 2 Dissertação - Beryl Eirene Lutz de Moura - 2017.pdf: 12051632 bytes, checksum: 125bb88e7ee0e8eabcbbaf1161a7c516 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Luciana Ferreira (lucgeral@gmail.com) on 2017-05-10T13:25:01Z (GMT) No. of bitstreams: 2 Dissertação - Beryl Eirene Lutz de Moura - 2017.pdf: 12051632 bytes, checksum: 125bb88e7ee0e8eabcbbaf1161a7c516 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2017-05-10T13:25:01Z (GMT).

description |
The family Cucurbitaceae Juss. is include in Cucurbitales order in the clade Eurosids I, 2295 spp., included in 129 tropical and temperate genera distributed in seven families of different morphological and ecological characteristics. The family has 98 genera and 975 species. In Brazil is represented by about 30 genera and 157 species. This work deals with the taxonomic study of plants of the Cucurbitaceae family Juss. found in the State of Goias, Brazil to contribute information to update the Flora of Brazil. Exsiccatae analyzes were performed deposited in national and international herbaria and conducting expeditions in the study area. 19 genera and 40 species in the area were located, so 09 genera and 28 species of native plants. Relative to native plants, Cayaponia Silva Manso gender had a greater number of species (8 spp.), followed by Melothria L. (6 spp.), Gurania (Schltdl.) Cogn. (4 spp.), Ceratosanthes Adans. (3 spp.) Psiguria Neck ex. Arn.and Sicyos L. (2 spp.), and the genres Melothrianthus Mart. Crov., Siolmatra Baill, Wilbrandia Silva Manso, are represented by only one species each. Pollen morphology of six native and two sub-spontaneous species of Cucurbitaceae occurring in the state of Goias, Midwest Region of Brazil, were analyzed with the goal of understanding the palynology and taxonomy of selected species. Pollen grains were acetolyzed, measured, described, photographed and electromicrographed. Analysis under the SEM was used to elucidate questions about the ornamentation of the exine. Pollen grains are in monads in Cayaponia podantha Cogn., Ceratosanthes tomentosa Cogn., Luffa operculata (L.) Cogn., Melothria campestris (Naudin) H. Schaefer & S. S. Renner, Momordica charantia L., Wilbrandia hibiscoides Silva Manso or tetrads in Gurania lobata (L.) Pruski and Psiguria umbrosa (Kunth) C. Jeffrey; average size, large or very large in monads and very large in tetrads. The openings ranged from pores in Cayaponia podantha, colpores in other monads and pores in tetrads. Regarding ornamentation, spiny sexine were registered in Cayaponia podantha, perforated sexine in Melothria campestris, micro-reticulated sexine in Gurania lobata and Psiguria umbrosa and reticulated sexine in other taxa. Results allowed the distinction between genera, indicating that the pollen morphology contributes to the taxonomic studies and the family is considered eurypalynous. These data emphasize the importance of pollen morphology for the diagnosis of genera into Cucurbitaceae. |
