Tuber ontogeny, morphology and vegetative reproduction of Gloriosa superba L

The ontogeny and morphology of the tuber of Gloriosa superba are investigated. This perennial organ (tuber) was previously classified as a rhizome, root stock or tuber. We consider this organ to be a hypopodial tuber mostly consisting of two metamorphous hypopodia with an apical bud enveloped by a prophyll, all covered by the remains of leaf bases. Separation of the mostly bilobed hypopodial tubers produced a higher percentage of flowering plants than undivided tubers. Die ontogenie en morfologie van die knolle van Gloriosa superba word in die artikel ondersoek. Hierdie meerjarige orgaan (knol) is voorheen as 'n risoom, wortelstok of knol geklassifiseer. Die skrywers beskou die knol as 'n hipopodiale knol wat meestal uit twee metamorfiese hipopodia met 'n apikale knop omring deur a profil bestaan. Die knolle word verder deur die reste van blaarbasisse omring. Verdeling van die meestal tweelobbige hipopodiale knolle het 'n hoër blomproduksie as onverdeelde knolle tot gevolg gehad.
