Germination of the polymorphic fruits of Bidens bipinnata

Year: 1984

Type: article

Abstract: The germination of three morphologically distinct categories of achenes of Bidens bipinnata was investigated. The long and medium length achenes germinated readily over a wide range of germination conditions. The short achenes showed relatively exacting germination requirements. Germination of the short achenes was enhanced by white light, red light, scarification, leaching and applied gibberellic acid and kinetin. The implications of the differences in germination behaviour are discussed. Die kieming van drie morfologies-verskillende tipes vrugte van Bidens bipinnata is ondersoek. Die lang en medium lengte vrugte het geredelik onder ’n wye reeks toestande gekiem. Die kort vrugte het egter meer spesifieke kiemingstoestande benodig. Kieming van hierdie vrugte is deur witlig, rooilig, skarifisering, uitloging, gibberellien- en kinetientoedienings bevorder. Die implikasies van hierdie kiemingsverskille word bespreek.
