Cytological Studies On Banisteriopsis C.b. Robinson Ex Small And Heteropterys Kunth (malpighiaceae)

Cytological studies were carried out on 6 species of Banisteriopsis and 4 species of Heteropterys (Malpighiaceae, Malpighioideae), collected in forest and cerrado areas of southeastern Brazil, and a cultivated one. No previous chromosome counts are known for 3 species of Banisteriopsis and 3 species of Heteroprerys. Chromosome numbers were obtained through mitotic (7 counts) and meiotic (5 counts) analysis. No meiotic abnormalities were encountered in the species studied, which presented high viable pollen rates. For the first time, karyomorphological characters were found for both genera, with a predominance of metacentric chromosomes. The chromosome number variation, based on x=5 and 10, with cases of polyploidy, and the similarity between the 2 related genera are discussed.663253259Anderson, W.R., Byrsonimoideae, a new sub-family of Malpighiaceae (1977) Biotropica, 7, pp. 5-18Floral conservatism in neotropical Malpighiaceae (1979) Biotropica, 11, pp. 219-223Chromosome numbers of neotropical Malpighiaceae (1993) Contr.

Cytological Studies In Climbers Of A Brazilian Forest Reserve

Cytological studies were carried out based on eleven species in seven families of climbers from the Santa Genebra Forest Reserve: Canavalia parviflora, Canavalia picta, Centrosema sagitattum, Phaseolus lunatus (Fabaceae), Dalechampia pentaphylla (Euphorbiaceae), Mascagnia anisopetala, Stigmaphyllon lalandianum (Malpighiaceae), Merremia macrocalyx (Convolvulaceae), Momordica charantia (Cucurbitaceae), Passiflora miersii (Passifloraceae). Their chromosome numbers and its distribution inside their genera were analyzed. In eight species the chromosomes were measured and for three of these species it was possible to construct the chromosomal ideograms based on karyological data. Five of these chromosome counts were made for the first time.634415420Agarwal, P.K., Roy, P., Natural polyploids in cucurbitaceae I.

Chromosome Studies In Gomidesia, Marlierea, Myrceugenia And Myrcia (myrtaceae, Subtribe Myrciinae)

In this paper we describe the chromosome numbers of several species of Myrtaceae (subtribe Myrciinae) from south-eastern Brazil, in order to help determine the circumscription and limits of this group. The chromosomal counts of 20 species were obtained, 17 of which are new. The number 2n = 22 occurs in almost all of species and genera analysed except for the polyploid species Gomidesia gaudichaudiana and two species of Myrcia, with 2n = 44. With these results, our knowledge of the chromosome number in the subtribe Myrciinae increased from 12 (2.2%) to 29 species (5.4%). The occurrence of 2n = 22 in species of the four genera analysed did not help resolve taxonomic questions relating to the distinction between Myrcia, Marlierea and Gomidesia. Although less frequent in Myrciinae, polyploidy appears to have had an important role in the evolution of this family, with high frequency in Eugeniinae (22.5% of Eugenia species) and Myrtinae (50% of the species, 75% in Psidium). © The Board of Trustees of the Royal Botanic Gardens, 2007.621113118Andrade, F.G., Forni-Martins, E.R., Estudos cromossômicos em espécies de Myrtaceae (1998) Genet.
