Trematolobelia: Seed Dispersal; Anatomy of Fruit and Seeds
THE ENDEMIC HAWAIIAN GENUS Trematolobelia (Lobeliaceae, or Campanulaceae, subfamily Lobelioideae) was erected on the basis of its distinctive fruit. This fruit has a seed-dispersal mechanism unique in the family. Assertions have been made by some workers that holes in the fruit wall are the work of insects, and are not related to the dispersal mechanism. This contention has been adequately disp...
متن کاملSeed abscission and fruit dehiscence required for seed dispersal rely on similar genetic networks.
Seed dispersal is an essential trait that enables colonization of new favorable habitats, ensuring species survival. In plants with dehiscent fruits, such as Arabidopsis, seed dispersal depends on two processes: the separation of the fruit valves that protect the seeds (fruit dehiscence) and the detachment of the seeds from the funiculus connecting them to the mother plant (seed abscission). Th...
متن کاملFruit size in wild olives: implications for avian seed dispersal
Frugivorous birds in the Mediterranean basin may disperse seeds using two different feeding behaviours: swallowing the fruit whole or pecking pieces of pulp. Swallowing is the common behaviour of frugivorous seed dispersers in the Mediterranean basin (Herrera 1984a) and most of the fleshy-fruited plants in the region rely on this bird feeding behaviour to disperse their seeds (Herrera 1984b, 19...
متن کاملn-Alkylresorcinol occurrence in Mercurialis perennis L. (Euphorbiaceae).
Investigation of the dichloromethane extracts from herbal and root parts of Mercurialis perennis L. afforded a mixture of 11 homologous n-alkylresorcinols (ARs) with saturated odd-numbered alkyl side chains (C15:0-C27:0). In addition to three predominant ARs (C19:0, C21:0 and C23:0), a number of minor ARs were identified by use of LC-MS/MS and GC-MS techniques. Among the compounds detected, fou...
متن کاملOil content, fruit and seed characteristics Ethiopian Jatropha (Jatropha curacas L.) provenances
For determining the oil content, seed and fruit characteristics of Ethiopian Jatropha provenances, the study was conducted in five regions of Ethiopia namely Southern Nation Nationalities Peoples Regional state, Amhara region, Tigria region, Oromia region and Benishangul Gumuz Regions, where Jatropha is found abundantly. A total of 23 Zones, 36 Weredas and 40 sampling sites were considered from...
