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...

It was previously demonstrated that, when solutions of hexose sugars such as glucose, fructose, or mannose are introduced into green leaves under aerobic conditions, an increase in sucrose is observed (l-3). The sucrose appears to be synthesized at the expense of the monosaccharides. Excised barley leaves infiltrated with 5 per cent glucose or fructose accumulated sucrose to a level of about 6 ...

Tiwul is a traditional Indonesian food with good functional properties regarding low glycemic index. However, like other tuber-based products, tiwul also faced nutritional deficiency issues. Therefore, this study aims to optimize the quality of by modifying formulation using different tuber flours and adding soybean flour as fortificant. Three kinds (cassava, sweet potato, canna) were used raw ...

A microcosm study was conducted in Okeechobee, County, Florida, to evaluate the P removal potential of several aquatic macrophytes and "unconventional" terrestrial crops cultured on dairy lagoon wastewaters. Existing conventional spray field crops in this region that are irrigated with dairy wastewaters are estimated to remove 23 mgP/m-'-day. Effects of season and hydraulic retention time (HRT)...

Plant biominerals are not always well characterized, although this information is important for plant physiology and can be useful for taxonomic purposes. In this work, fresh plant material of seven wild neotropical species of genus Canna, C. ascendens, C. coccinea, C. indica, C. glauca, C. plurituberosa, C. variegatifolia and C. fuchsina sp. ined., taken from different habitats, were studied t...
