Tracking the development of the petaloid fertile stamen in Canna indica: insights into the origin of androecial petaloidy in the Zingiberales
Flowers of the order Zingiberales demonstrate a remarkable trend of reduction in the number of fertile stamens; from five or six fertile, filamentous stamens bearing two thecae each in Musaceae and Strelitziaceae to just a single petaloid stamen bearing a single theca in Cannaceae and Marantaceae. As one progresses from ancestral to derived floral forms, 5-6 fertile stamens are replaced by 4-5 ...
متن کاملPollination and breeding system of Canna paniculata (Cannaceae) in a montane Atlantic Rainforest: asymmetric dependence on a hermit hummingbird
We studied the pollination biology of Canna paniculata (Cannaceae), a plant species common in the Atlantic Rainforest of southeastern Brazil. The species presents specialized ornithophilous flowers, which in our study area are solely pollinated by the hermit hummingbird Phaethornis eurynome. Although C. paniculata is capable of bearing fruit after self-pollination, it requires pollinators for r...
متن کاملFoliar Application of Anti-frost Solution Influences Physiological and Biochemical Parameters in Bougainvillea, Canna and Petunia
Frost is the coating or deposit of ice that may form in cold conditions, usually overnight. If the temperature drops far enough for the plant cells to freeze, non hardy plants will die. Therefore, a research was laid out to study the influence of an anti-frost solution on growth, flowers quality and biochemical parameters of ornamental plants. The anti-frost solution was applied as foliar spray...
متن کاملBetween Cancer and Capricorn: Phylogeny, evolution and ecology of the primarily tropical Zingiberales
The Zingiberales are a group of primarily tropical monocots that includes eight families, ca. 96 genera, and about 2,000 species. Phylogenetic results based on sequence data and morphology show that the four “banana-families” (Musaceae, Lowiaceae, Strelitziaceae, and Heliconiaceae) share the plesiomorphic state of five or six fertile stamens and comprise a basal paraphyletic assemblage. The fou...

Population growth (length-weight relationship), and reproductive potential (e.g. fecundity, and sex-ratio) of five important fish species (‘mola’: Amblypharyngodon mola, ‘puti’: Puntius sophore, ‘tengra’: Mystus vittatus, ‘shing’: Heteropneustes fossilis and ‘taki’: Channa punctatus) collected from two important fresh water bodies (nam...
